get label control value from radgrid

[Ron]

Hi,

Can someone help me figure out how to get a label control text value from grid item template column?

<telerik:GridTemplateColumn DataField="Amount" HeaderText="Amount" UniqueName="Amount">
                   <ItemStyle BorderStyle="NotSet" CssClass="test" HorizontalAlign="Right" Width="75px" />
                   <HeaderStyle HorizontalAlign="Center" Width="85px" />
                   <ItemTemplate>
                       <asp:Label ID="lblAmount" runat="server" Text='<%# Eval("Amount") %>'
                           Width="75"></asp:Label>
                   </ItemTemplate>
                   <EditItemTemplate>
                       <asp:Label ID="lblAmount" runat="server" Text='<%# Eval("Amount") %>'
                           Width="75"></asp:Label>
                   </EditItemTemplate>
               </telerik:GridTemplateColumn>

Label amount = (Label)item.FindControl("lblAmount");
double? amount= (item["Amount"].FindControl("lblAmount") as Label).Text;

I've tried both ways and neither seems to work. Thanks in advance.

Hello Ron,

I tried the same scenario and it is working as expected in my end. Make sure that it is getting inside the loop when you are accessing the Label in ItemDataBound event. Here is the sample code that I tried.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
   if(e.Item is GridDataItem)
   {
     GridDataItem item = (GridDataItem)e.Item;
     Label lbl = (Label)item.FindControl("lblAmount");
     string value=lbl.Text;
   }
}

Thanks,
Shinu.

Hi Shinu,

Does it have to be called from the item data bound event? because I have a method that gets text box values , combo box values and everything works fine except when I try to get the value of a label control which is not a rad control. Here is the complete method.

private void SaveInvoiceItems()
   {
       try
       {
           foreach (GridDataItem item in grdInvoiceItems.Items)
           {
               int id = (int)item.OwnerTableView.DataKeyValues[item.ItemIndex]["Id"];
               string lineItem = (item["Items"].FindControl("ddlItems") as RadComboBox).Text;
               string description = (item["Description"].FindControl("txtDescription") as RadTextBox).Text;
               double? price = (item["Price"].FindControl("txtPrice") as RadNumericTextBox).Value;
               double? qty = (item["Qty"].FindControl("txtQty") as RadNumericTextBox).Value;
               double? discount = (item["Discount"].FindControl("txtDiscount") as RadNumericTextBox).Value;
               double tax = double.Parse(lblTaxes.Text);

               Label amount = (Label)item.FindControl("lblAmount");

               InvoiceRecurring.UpdateRecurringInvoiceItems(id, lineItem, description, Convert.ToInt32(price),
                   Convert.ToInt32(qty), Convert.ToDouble(discount), tax, Convert.ToDouble(amount));
           }
       }
       catch (Exception ex)
       {
           Response.Write(ex.Message);
       }
   }

Thanks,
Ron.

Hello Ron,

I am attaching a sample where I have shown how to get the label control and have demonstrated a better way to extract the field values for a given grid row.
