Setting textbox text in an update panel from a gridview rowcommand

Setting textbox text in an update panel from a gridview rowcommand - c#

I am trying to update the values of textboxes within an update panel from the rowcommand of a gridview, also within the update panel. The rowcommand is firing the update panel and running through the OnRowCommand code, however the values of the textboxes simply aren't being updated.
I am not getting any errors, and I have checked that I am not simply entering blank strings by tracing the value of the class I am supplying the values from.
Here is my code:
ASPX
<asp:Panel ID="pnlInspectorExpenses" CssClass="expenses" runat="server" Visible="false">

<asp:UpdatePanel ID="uPnlInspectorExpenses" runat="server">

ASPX.CS
protected void grdInspectorExpenses_RowCommand(object sender, GridViewCommandEventArgs e)
{
Trace.Warn("0");
if (e.CommandName == "Edit")
{
Trace.Warn("1");
int rowIndex = int.Parse(e.CommandArgument.ToString());
int ExpID = int.Parse(grdInspectorExpenses.DataKeys[rowIndex].Values[0].ToString());
hdnInsExpID.Value = ExpID.ToString();
List<ExpenseInfo> Expenses = IC.ExpenseSelect(ExpID);
ExpenseInfo Expense = Expenses[0];
txtInsExpDate.Text = Expense.ExpDate.ToString();
txtInsExpDesc.Text = Expense.ExpDescription;
ddlExpenseType.Items.FindByValue(Expense.ExpType).Selected = true;
txtInsExpCurrency.Text = Expense.ExpCurrency;
txtInsExpForVal.Text = Expense.ExpForeignCost.ToString();
txtInsExpExcRate.Text = Expense.ExpExchangeRate.ToString();
txtInsExpLocVal.Text = Expense.ExpLocalCost.ToString();
txtInsExpRecNo.Text = Expense.ExpReceiptNo;
Trace.Warn(Expense.ExpReceiptNo);
}
else if (e.CommandName == "Delete")
{
}
}

I figured this out in the end. It seems that if you name the CommandName "Edit", it calls the 'OnRowEditing' function, which was undefined. Therefore I just renamed the CommandName to "EditExpenses" instead. I did the same for the Delete command as well.

Please set the UpdatePanel's UpdateMode to Always to see if this makes a difference. For rules and conditions when an UpdatePanel content is updated, see here under Remarks: http://msdn.microsoft.com/en-us/library/system.web.ui.updatepanel.updatemode(v=vs.110).aspx

c# code:-
private void ProcessFile(string filename, string filePath)
{
try
{
DataRow dr;
string line;
string content = "";
dr = tblFileContent.NewRow();
// Read the file and display it line by line.
//using (StreamReader file = new StreamReader(#"C:\Upload.txt"))
using (StreamReader file = new StreamReader(filePath))
{
/*while ((line = file.ReadLine()) != null)
{
content = line + "\n";
}*/
txtContents.Text += filename+"\n";
file.Close();
}
}
}

From your current snippets you can open file like this:-
string strfullPath = System.IO.Path.Combine(filepath, filename);
using (StreamReader steamReader = new StreamReader(strfullPath))
{
string content = steamReader.ReadToEnd();
}
Update1
If you want to open it with Notepad you need
System.Diagnostics.Process.Start()
Like:
Process.Start("notepad.exe", strfullPath);
If you want to open with its own editor than:
Process.Start(strfullPath);
Some how like this:-
//Process.Start(#"c:\myfile.txt");
Update2
If files are located at remote server then You would need to be authenticated on the share folder before you can access the files. For remote server this Link is worthy.

lblamount.Text = total.ToString();
}
Here i had given "Showfooter"=true property but still it's not displaying
But while debug value(sumofamount) is assign to label.text

this line apply css for the gridview infooter:
<FooterStyle CssClass="hide" />
i think that this can hide the footr of gridview pls check this css...

Displaying data from two database tables on one page using Dynamic Data

Hi can anyone help me with this. I am using dynamic data and have created a custom page which displays all orders within a database table. Once someone selects an order I would like it display all the individual items for that order. This data is stored in another table but within the same database. I found a very useful article on here Asp.net Dynamic data multiple relational entities on single page which I think gives me pretty much my answer but I am stuck where it comes to the part about implementing IEnumerable (I am trying to implement version 2 on the page). I have done some reading on IEnumerable but I am really lost. I'm not sure if I'm supposed to create a new class. Can anyone help?

Any help would be greatly appreciated.

My approach is as follows
First I display list of all orders selected in a grid view.
When user selects to see detail of any order i fire grid view row command event and pass order id as command argument.
Then in code behind i get order entity with the help of order id passed in step 2 and along with order entity i get order details and display it in second grid view.

Thank you Nimit for your response. It was very useful. If it helps anyone else I found exactly what I was looking for at http://www.asp.net/web-forms/tutorials/getting-started-with-ef/the-entity-framework-and-aspnet-getting-started-part-4.

My Client side code for button
protected void btnInsert_Click(object sender, EventArgs e)
{
try
{
int productID, quantity;
string stockType;
DateTime stockDate;
productID = int.Parse(ddlprdctname.SelectedValue);
quantity = int.Parse(txtquantity.Text.Trim());
stockType = ddlstocktype.SelectedValue.ToString().Trim();
stockDate = DateTime.Parse(txtstockdate.Text.Trim());
ProductStock prdctstock = new ProductStock();
prdctstock.ProductID = productID;
prdctstock.Quantity = quantity;
prdctstock.StockType = stockType;
prdctstock.StockDate = stockDate;
if (new InsertAction().InsertData(prdctstock))
{
lblmsg.Text = "Inserted Sucessfully";
ViewPanel.Visible = true;
}
else
{
lblmsg.Text = "Please Check all the fields";
}
BindGridView();
ProductInfo prdctinfo = new ProductInfo();
if (stockType == "In")
{
prdctinfo.Quantity += quantity;
}
if (stockType == "Out")
{
prdctinfo.Quantity -= quantity;
}
}
catch (Exception ex)
{
if (ex is FormatException)
{
lblmsg.Text = "Character value are not allowed";
}
else
{
lblmsg.Text = ex.Message;
}
}
}

Put the breakpoint somewhere where it hits. Look at the call stack and step over to the point when you find why it is not going to the method you want to trigger.
Can't do much without more information.
Hope this helps

I saw few unwanted code's
1) please remove the ValidationGroup="vg1" in your all asp.net controls except button .
2) Don't use panel , some time the button click not working on using panel control, so please use table instead of panel .(or remove the asp:panel control )
3) and must check the button click event same as server side .
4) If you give me our server side code then i will response you !!

Setting textbox text in an update panel from a gridview rowcommand - c#

I figured this out in the end. It seems that if you name the CommandName "Edit", it calls the 'OnRowEditing' function, which was undefined. Therefore I just renamed the CommandName to "EditExpenses" instead. I did the same for the Delete command as well.

Please set the UpdatePanel's UpdateMode to Always to see if this makes a difference. For rules and conditions when an UpdatePanel content is updated, see here under Remarks: http://msdn.microsoft.com/en-us/library/system.web.ui.updatepanel.updatemode(v=vs.110).aspx
