I believe this is probably the issue:
for (int i = 0; i <= dt_C_Code.Rows.Count; ; i++) {...}
Please consider substituting foreach (DataRow row in dt_C_Code.Rows) { ...}
If it's important which row should logically come "first", then please consider using an order by clause in your SQL statement.

Now problem is solve the problem is that break key word.

Insert / Send RefNbr to another database in Acumatica ERP System

I have created a payment in Checks and Payments screen of Acumatica screen and released it. Please refer to the following screenshot.
I've already create the following code to provide it.
protected virtual void APPayment_RowPersisted(PXCache sender, PXRowPersistedEventArgs e)
{
string serverJade, dbJade, userJade, passJade;
serverJade = Properties.Settings.Default.serverJade;
dbJade = Properties.Settings.Default.dbJade;
userJade = Properties.Settings.Default.userJade;
passJade = Properties.Settings.Default.passJade;
APPayment app = (APPayment)e.Row;
if (e.Operation == PXDBOperation.Update && e.TranStatus == PXTranStatus.Completed)
{
if (app.DocType == APPaymentType.Check || app.DocType == APPaymentType.Prepayment)
{
if (app.RefNbr != null)
{
using (SqlConnection con = new SqlConnection("server = " + serverJade + "; database = " + dbJade + "; user = " + userJade + "; password = " + passJade + ""))
{
con.Open();
//---- query to update a field in the table of another database -------//
string query = "Update EVMaster set AcuRefNo = '" + app.RefNbr + "' where VchNo = 'DD02/16-VIII/12206-VCH-01'";
using (SqlCommand com = new SqlCommand(query, con))
{
SqlDataReader sdr = com.ExecuteReader();
sdr.Close();
}
con.Close();
}
}
}
}
}
I already tried to debug this code, but didn't work. And then I try to use this follwing code.
protected virtual void APPayment_RowPersisted(PXCache sender, PXRowPersistedEventArgs e)
{
string serverJade, dbJade, userJade, passJade;
serverJade = Properties.Settings.Default.serverJade;
dbJade = Properties.Settings.Default.dbJade;
userJade = Properties.Settings.Default.userJade;
passJade = Properties.Settings.Default.passJade;
APPayment app = (APPayment)e.Row;
if (app.DocType == APPaymentType.Check || app.DocType == APPaymentType.Prepayment)
{
if (app.RefNbr != null)
{
using (SqlConnection con = new SqlConnection("server = " + serverJade + "; database = " + dbJade + "; user = " + userJade + "; password = " + passJade + ""))
{
con.Open();
//---- query to update a field in the table of another database -------//
string query = "Update EVMaster set AcuRefNo = '" + app.RefNbr + "' where VchNo = 'DD02/16-VIII/12206-VCH-01'";
using (SqlCommand com = new SqlCommand(query, con))
{
SqlDataReader sdr = com.ExecuteReader();
sdr.Close();
}
con.Close();
}
}
}
}
The codes above is worked, I just remove the if condition (if (e.Operation == PXDBOperation.Update && e.TranStatus == PXTranStatus.Completed)
{}).
But it's not my goal, I have to filter document only for Doc Status = 'printed' from the document, and this process will be executed when 'Release' button was clicked.
And also any idea how to get all records in APAdjust of the current document ? because I need to comparing adjgrefnbr in apadjust with refnbr in APInvoice based on adjgrefnbr (apadjust) = refnbr (apinvoice). So I can get also all records of APinvoice based on refnbr (APinvoice) = ajgrefnbr (current apadjust). This condition is used to make 'where' condition of query not have to be hardcoded, I will used variable to provide it.
any suggestions to sove this problem ?

Below is an example showing how to extend Release process for checks and subscribe to RowPersisted handler for the APRegister DAC to save released document RefNbr to another database:
public class APPaymentEntryExt : PXGraphExtension<APPaymentEntry>
{
public PXAction<APPayment> release;
[PXUIField(DisplayName = "Release", MapEnableRights = PXCacheRights.Update, MapViewRights = PXCacheRights.Update)]
[PXProcessButton]
public IEnumerable Release(PXAdapter adapter)
{
PXGraph.InstanceCreated.AddHandler<APReleaseProcess>((graph) =>
{
graph.RowPersisted.AddHandler<APRegister>(APReleaseCheckProcess.APPaymentRowPersisted);
});
return Base.release.Press(adapter);
}
}
public class APReleaseChecksExt : PXGraphExtension<APReleaseChecks>
{
protected virtual void ReleaseChecksFilter_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
{
var row = e.Row as ReleaseChecksFilter;
if (row == null) return;
Base.APPaymentList.SetProcessDelegate(list =>
{
PXGraph.InstanceCreated.AddHandler<APReleaseProcess>((graph) =>
{
graph.RowPersisted.AddHandler<APRegister>(APReleaseCheckProcess.APPaymentRowPersisted);
});
APReleaseChecks.ReleasePayments(list, row.Action);
});
}
}
By executing quite simple BQL query you can access APAdjust records associated with released check within handler for the RowPersisted event:
public static class APReleaseCheckProcess
{
public static void APPaymentRowPersisted(PXCache sender, PXRowPersistedEventArgs e)
{
if (e.TranStatus == PXTranStatus.Completed && e.Operation == PXDBOperation.Update)
{
var doc = e.Row as APPayment;
if (doc != null && doc.Released == true)
{
// save RefNbr to another database
foreach (APAdjust oldadj in PXSelect<APAdjust,
Where<
APAdjust.adjgDocType, Equal<Required<APPayment.docType>>,
And<APAdjust.adjgRefNbr, Equal<Required<APPayment.refNbr>>,
And<APAdjust.adjNbr, Less<Required<APPayment.lineCntr>>>>>>
.Select(sender.Graph, doc.DocType, doc.RefNbr, doc.LineCntr))
{
}
}
}
}
}

How can I declare cookie

I am trying to make this code work fine as i can but i couldnt,i am using cookie and i want to rebind my ListView depending on cookie Location but i am getting error message: "Must declare the scalar variable "#Location"."
protected void Sortcarbtn_Click(object sender, EventArgs e)
{
HttpCookie cookie = Request.Cookies.Get("Location");
using (SqlConnection carcon = new SqlConnection(ConfigurationManager.ConnectionStrings["BeravaConnectionString"].ConnectionString))
if (cookie != null)
{
string CarSqlST = #"SELECT DISTINCT AdsID, Section, Category, Country, Maker, Gear, Condition, Status, State, City, AdsTit,
SUBSTRING(AdsDesc,1,155) as AdsDesc, Year, AdsPrice, Img1 From ads Where 1=1 AND Category=#CATE AND Country = #Location ";
var Location = Convert.ToString(cookie["Location"]);
var cat = Convert.ToString(Request.QueryString["cat"]);
string condition = "";
if (barndcardrlst.SelectedValue != "")
{
condition += " and Maker='" + barndcardrlst.SelectedValue + "'";
}
if (GearDrDw.SelectedValue != "")
{
condition += " and Gear='" + GearDrDw.SelectedValue + "'";
}
if (carstatedrdolst.SelectedValue != "")
{
condition += " and State='" + carstatedrdolst.SelectedValue + "'";
}
if (citiesdrdolst.SelectedValue != "")
{
condition += " and City='" + citiesdrdolst.SelectedValue + "'";
}
if (CarCondDrDw.SelectedValue != "")
{
condition += " and Condition='" + CarCondDrDw.SelectedValue + "'";
}
if (CarstusDRDL.SelectedValue != "")
{
condition += " and Status='" + CarstusDRDL.SelectedValue + "'";
}
if ((CarPriceFrmDrDw.SelectedValue != "") && (CarPriceToDrDw.SelectedValue != ""))
{
condition += " and AdsPrice BETWEEN " + CarPriceFrmDrDw.SelectedValue + " AND " + CarPriceToDrDw.SelectedValue;
}
if ((CarYearfrmDrDw.SelectedValue != "") && (CarYeartoDrDw.SelectedValue != ""))
{
condition += " and Year BETWEEN " + CarYearfrmDrDw.SelectedValue + " AND " + CarYeartoDrDw.SelectedValue;
}
DataTable cdt = new DataTable();
carcon.Open();
SqlCommand ccmd = new SqlCommand();
ccmd.Connection = carcon;
ccmd.CommandType = CommandType.Text;
ccmd.Parameters.AddWithValue("#Country", Location);
ccmd.Parameters.AddWithValue("#CATE", cat);
ccmd.CommandText = CarSqlST + condition;
SqlDataAdapter ad = new SqlDataAdapter();
ad.SelectCommand = ccmd;
ad.Fill(cdt);
cateshowlistview.DataSource = cdt;
cateshowlistview.DataBind();
}
}

Change "#Country" in
ccmd.Parameters.AddWithValue("#Country", Location);
to be "#Location"
ccmd.Parameters.AddWithValue("#Location", Location);
you defined the Country in the SQL Statement to be #Location
string CarSqlST = #"SELECT ... AND Category=#CATE AND Country = #Location ";
Update
To prevent SQL Injection hacks and to allow for SQL to reuse the query options all the fileters where you are concat the string together you should just use SQL Parameters. To make it easy I create a parameters dictionary to add to. Then at the end loop through the dictionary to fill in the SQL Parameters. I also switched it to string builder since could be doing a lot of string concats. I didn't test this code because I don't have your objects or tables or connections.
using (var carcon = new SqlConnection(ConfigurationManager.ConnectionStrings["BeravaConnectionString"].ConnectionString)))
{
if (cookie != null)
{
// Parameters for SQL
var parameters = new Dictionary<string, object>();
// string builder to build up SQL Statement
var CarSqlST = new StringBuilder(
"SELECT DISTINCT AdsID, Section, Category, Country, Maker, Gear, Condition, Status, State, City, AdsTit, " +
"SUBSTRING(AdsDesc,1,155) as AdsDesc, Year, AdsPrice, Img1 From ads " +
"Where Category = #pCATE AND Country = #pLocation ");
parameters.Add("#pCATE", Request.QueryString["cat"].ToString());
parameters.Add("#pLocation", cookie["Location"]);
if (barndcardrlst.SelectedValue != "")
{
CarSqlST.Append(" and Maker= #pMaker");
parameters.Add("#pMaker", barndcardrlst.SelectedValue);
}
if (GearDrDw.SelectedValue != "")
{
CarSqlST.Append(" and Gear= #pGear");
parameters.Add("#pGear", GearDrDw.SelectedValue);
}
if (carstatedrdolst.SelectedValue != "")
{
CarSqlST.Append(" and State= #pState");
parameters.Add("#pState", carstatedrdolst.SelectedValue);
}
if (citiesdrdolst.SelectedValue != "")
{
CarSqlST.Append(" and State= #pCity");
parameters.Add("#pCity", citiesdrdolst.SelectedValue);
}
if (CarCondDrDw.SelectedValue != "")
{
CarSqlST.Append(" and Condition= #pCondition");
parameters.Add("#pCondition", CarCondDrDw.SelectedValue);
}
if (CarstusDRDL.SelectedValue != "")
{
CarSqlST.Append(" and Status= #pStatus");
parameters.Add("#pStatus", CarstusDRDL.SelectedValue);
}
if ((CarPriceFrmDrDw.SelectedValue != "") && (CarPriceToDrDw.SelectedValue != ""))
{
CarSqlST.Append(" and AdsPrice BETWEEN #pLowPrice AND #pHighPrice");
parameters.Add("#pLowPrice", CarPriceFrmDrDw.SelectedValue);
parameters.Add("#pHighPrice", CarPriceToDrDw.SelectedValue);
}
if ((CarYearfrmDrDw.SelectedValue != "") && (CarYeartoDrDw.SelectedValue != ""))
{
CarSqlST.Append(" and Year BETWEEN #pLowYear AND #pHighYear");
parameters.Add("#pLowYear", CarYearfrmDrDw.SelectedValue);
parameters.Add("#pHighYear", CarYeartoDrDw.SelectedValue);
}
DataTable cdt = new DataTable();
SqlCommand ccmd = carcon.CreateCommand();;
ccmd.CommandType = CommandType.Text;
// Add all the parameters into this command
foreach (var parameter in parameters)
{
ccmd.Parameters.Add(parameter.Key, parameter.Value);
}
// set the command text from string builder
ccmd.CommandText = CarSqlST.ToString();
SqlDataAdapter ad = new SqlDataAdapter();
ad.SelectCommand = ccmd;
}
}
You could have created the command at the top and filled in the sql parameters right away instead of the dictionary but I like the dictionary approach better in case something happens - exception or we need to bail we never created the SQL Command.

ASP.NET Repeater and CollectionPager [duplicate]

I have a problem with the collectionpager and repeater. When I load the page, collectionpager is working fine.. But when I click the search button and bind new data, clicking the page 2 link, it is firing the page_load event handler and bring all the data back again... Notice: All controls are in an UpdatePanel.
protected void Page_Load(object sender, EventArgs e){
if (!IsPostBack)
{
kayit_getir("SELECT Tbl_Icerikler.ID,Tbl_Icerikler.url,Tbl_Icerikler.durum,Tbl_Icerikler.baslik,Tbl_Icerikler.gunc_tarihi,Tbl_Icerikler.kayit_tarihi,Tbl_Icerikler.sira,Tbl_Kategoriler.kategori_adi FROM Tbl_Icerikler,Tbl_Kategoriler where Tbl_Kategoriler.ID=Tbl_Icerikler.kategori_id ORDER BY Tbl_Icerikler.ID DESC,Tbl_Icerikler.sira ASC");
}}
public void kayit_getir(string SQL){
SqlConnection baglanti = new SqlConnection(f.baglan());
baglanti.Open();

da.Fill(dt);
if (dt.Rows.Count > 0)
{

}
else

}

the code is very bad and you should completely review all of it.
the issue is every time the page load is executed it initializes again you query to the default one (the one with not filter) you should find a way to store somewhere the last query has been execute when you order/filtering your data.
Anyway the are lot of example on the web showing what you are trying to achieve
the below is just one of them
http://www.codeproject.com/KB/webforms/ExtendedRepeater.aspx

try this EnableViewState="false"

You have to bind the CollectionPager again on your search.

Sending changes from multiple tables in disconnected dataset to SQLServer

We have a third party application that accept calls using an XML RPC mechanism for calling stored procs.
We send a ZIP-compressed dataset containing multiple tables with a bunch of update/delete/insert using this mechanism. On the other end, a CLR sproc decompress the data and gets the dataset.
Then, the following code gets executed:
using (var conn = new SqlConnection("context connection=true"))
{
if (conn.State == ConnectionState.Closed)
conn.Open();
try
{
foreach (DataTable table in ds.Tables)
{
string columnList = "";
for (int i = 0; i < table.Columns.Count; i++)
{
if (i == 0)
columnList = table.Columns[0].ColumnName;
else
columnList += "," + table.Columns[i].ColumnName;
}
var da = new SqlDataAdapter("SELECT " + columnList + " FROM " + table.TableName, conn);
var builder = new SqlCommandBuilder(da);
builder.ConflictOption = ConflictOption.OverwriteChanges;
da.RowUpdating += onUpdatingRow;
da.Update(ds, table.TableName);
}
}
catch (....)
{
.....
}
}
Here's the event handler for the RowUpdating event:
public static void onUpdatingRow(object sender, SqlRowUpdatingEventArgs e)
{
if ((e.StatementType == StatementType.Update) && (e.Command == null))
{
e.Command = CreateUpdateCommand(e.Row, sender as SqlDataAdapter);
e.Status = UpdateStatus.Continue;
}
}
and the CreateUpdateCommand method:
private static SqlCommand CreateUpdateCommand(DataRow row, SqlDataAdapter da)
{
string whereClause = "";
string setClause = "";
SqlConnection conn = da.SelectCommand.Connection;
for (int i = 0; i < row.Table.Columns.Count; i++)
{
char quoted;
if ((row.Table.Columns[i].DataType == Type.GetType("System.String")) ||
(row.Table.Columns[i].DataType == Type.GetType("System.DateTime")))
quoted = '\'';
else
quoted = ' ';
string val = row[i].ToString();
if (row.Table.Columns[i].DataType == Type.GetType("System.Boolean"))
val = (bool)row[i] ? "1" : "0";
bool isPrimaryKey = false;
for (int j = 0; j < row.Table.PrimaryKey.Length; j++)
{
if (row.Table.PrimaryKey[j].ColumnName == row.Table.Columns[i].ColumnName)
{
if (whereClause != "")
whereClause += " AND ";
if (row[i] == DBNull.Value)
whereClause += row.Table.Columns[i].ColumnName + "=NULL";
else
whereClause += row.Table.Columns[i].ColumnName + "=" + quoted +
val + quoted;
isPrimaryKey = true;
break;
}
}
/* Only values for column that is not a primary key can be modified */
if (!isPrimaryKey)
{
if (setClause != "")
setClause += ", ";
if (row[i] == DBNull.Value)
setClause += row.Table.Columns[i].ColumnName + "=NULL";
else
setClause += row.Table.Columns[i].ColumnName + "=" + quoted +
val + quoted;
}
}
return new SqlCommand("UPDATE " + row.Table.TableName + " SET " + setClause + " WHERE " + whereClause, conn);
}
However, this is really slow when we have a lot of records.
Is there a way to optimize this or an entirely different way to send lots of udpate/delete on several tables? I would really much like to use TSQL for this but can't figure a way to send a dataset to a regular sproc.
Additional notes:
We cannot directly access the SQLServer database.
We tried without compression and it was slower.

If you're using SQL Server 2008, you should look into MERGE
Look here for more info on MERGE
