How to hide duplicate data from Gridview? - c#

how am i be able to hide those duplicate columns using gridview command?
im using
nested gridview and left Outer Join on sqlcommand i joined two database.. so yeah this is my next problem
this is my code
protected void NewConnection()
{
SqlCommand cmd = new SqlCommand("SELECT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
conn.Close();
GridView1.DataSource = ds;
GridView1.DataBind();
GroupGridView(GridView1.Rows, 0,0);
GridView1.Columns[3].Visible = false;
GridView1.Columns[4].Visible = false;
GridView1.Columns[7].Visible = false;
GridView1.Columns[8].Visible = false;
GridView1.Columns[9].Visible = false;
GridView1.Columns[10].Visible = false;
GridView1.Columns[11].Visible = false;
foreach (GridViewRow Separate in GridView1.Rows)
{
GridView gv2 = ((GridView)Separate.FindControl("GridView2"));
gv2.DataSource = ds;
gv2.DataBind();
string strfirstname = ((Label)Separate.FindControl("lblfirstname")).Text;
string strmiddlename=((Label)Separate.FindControl("lblmiddlename")).Text;
string strlastname = ((Label)Separate.FindControl("lbllastname")).Text;
string strage = ((Label)Separate.FindControl("lblage")).Text;
string strsex = ((Label)Separate.FindControl("lblsex")).Text;
string stramount = ((Label)Separate.FindControl("lblamount")).Text;
string strID1 = ((Label)Separate.FindControl("lblid")).Text;
foreach (GridViewRow grouplist in gv2.Rows)
{
string strID2 = ((Label)grouplist.FindControl("lblfriendswith2")).Text;
if (strID1 == strID2)
{
grouplist.Visible = true;
}
else
{
grouplist.Visible = false;
}
}
}
}
and this is my asp for gridview1 and gridview2

If you don't need the duplicate data Use distinct in query.
So your SqlCommand should look like,
SqlCommand cmd = new SqlCommand("SELECT DISTINCT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);


The problem is not your GridView control, the data binded to the GridView is the real issue, since the task of the GridView is just to show data. Performing a LEFT OUTER JOIN you're getting a lot of duplicates. Use the DISTINCT statement to remove duplicates:
SqlCommand cmd = new SqlCommand("SELECT DISTINCT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);

In code behind I have:
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
string purchaseRequisitionID = gvRequisitions.DataKeys[e.Row.RowIndex].Value.ToString();
GridView gvItems = (GridView)e.Row.FindControl("gvItems");
// new code to send reference to gvItems_RowDataBound
gvItems.RowDataBound += new GridViewRowEventHandler(gvItems_RowDataBound);
int id = Convert.ToInt32(purchaseRequisitionID);
using (SqlConnection conn = new SqlConnection(constr))
{
using(SqlCommand comm = new SqlCommand("procItems_CRUD"))
{
comm.Parameters.AddWithValue("#Action", "SELECT");
comm.Parameters.AddWithValue("#ID", id);
using(SqlDataAdapter sda = new SqlDataAdapter())
{
comm.CommandType = CommandType.StoredProcedure;
comm.Connection = conn;
sda.SelectCommand = comm;
using(DataTable dt = new DataTable())
{
sda.Fill(dt);
gvItems.DataSource = dt;
gvItems.DataBind();
}
}
}
}
}
}
And:
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if(ddlMeasure == null)
{
}
}
}
But I cannot see the drop down list as it returns a null value (as I know it is not a DataRow) but how can I see the footer row and the elements in footer row so that I can add another Item to the order/populate DropDownList etc.
Have been trying to sort this for some time and cannot find a working solution so any pointer(s) will be very much appreciated.

You need to use DataControlRowType.Footer.
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
//check if the row is a footer row
if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if (ddlMeasure != null)
{
ddlMeasure.Items.Insert(0, new ListItem("DLL Found!", "-1"));
}
}
}

using checkbox to select and delete row from gridiew datasource = session C# .net

I have been searching on here and other sites for three days for a solution. I need to select one or more rows (using checkbox) and delete selected row(s) from a gridview who's datasource is a session datatable as you will see. Not interested in SQLConnections or LINQ Entities. As a result I am not sure if I need to use e.commandarguments, or how to go about it, but I have tried them with no luck.
Error is visible and clearly commented on CART.ASPX.CS page inside the following method
if (chkRemCart != null && chkRemCart.Checked)
Any assistance would be greatly appreciated and if you require any further coding or explanations to help with a solution, just ask.
Thank you in advance.

When the add button is clicked btnAdd_click inserts data twice. Also I am not getting any exception errors in btnadd_click code.

When I click on add button, footer item data will insert into my database but is insert twice. It is in debug mode and jumping around everywhere.
it show "The process or thread has changed since last step."

You are sending the insert command again by calling gvEmpList.DataSource = GetData(cmd); inside btnAdd_Click. Please check it. The cmd object inside btnAdd_Click is an insert command.

Remove following code from btnAdd_Click
gvEmpList.DataSource = GetData(cmd);
gvEmpList.DataBind();
And call following method
BindData();

foreach loop for gridview.row[e.rowindex]

I have wired a gridSearchResults_RowUpdating event for everytime an update link button is clicked. What I want to do is loop through the row at the event rowindex and add the textbox value in the row cell to a string collection. I am having troubh accessing the textbox in the cell. If this doesn't make sense my code should help make things clearer.

C#
protected void gridSearchResults_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = gridSearchResults.Rows[e.RowIndex];
foreach (gridviewrow c in gridSearchResults.Rows[e.RowIndex])
{
}
}
So does anyone know a good way of looping through the cells of a gridview row and grabbing the textbox value in the gridview row cell. Thanks

Try this:
foreach (TableCell cell in gv.Rows(e.RowIndex).Cells)
{
TextBox txt1 = (TextBox)cell.FindControl("txtControlName");
// or if you don't want to hard code the control name and assuming that there is only 1 control in the cell then use this:
TextBox txt2 = (TextBox)cell.Controls(0);
}

Gridview edit mode for more that one row

I have a Gridview that allows user to edit and delete the records. I am using .net 3.5 using C#.
When I have just one record my edit command is working fine but problem comes when there are more that 1 record in my gridview.
In this case while binding the controls it it is unable to find the controls the second time and thus throws the error.
Here is my code:
protected void gdScheduleNew_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (ViewState["Updating"].Equals(true))
{
TextBox txtactsta = (TextBox)e.Row.FindControl("txtactualstartDate");
TextBox txtactend = (TextBox)e.Row.FindControl("txtactualendDate");
LinkButton lnkUpdate = (LinkButton)e.Row.FindControl("lnkUpdate");
txtactsta.Attributes.Add("ReadOnly", "true");
txtactend.Attributes.Add("ReadOnly", "true");
}
}
}
markup code is:

The error is on this line: txtactsta.Attributes.Add("ReadOnly", "true");:
object reference no set to an instance of object
How can I fix this?

Doesn't gdScheduleNew_RowDataBound get called for every row in your gridview? txtactualstartDate and txtactualendDate only exist on edit rows, they do not exist on non editing rows.
Try this:
if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Edit)
