How to retrieve text box value set from clientside at server postback in radgrid?

[Harshit]

I have standard asp textbox as template column in radgrid and I change value of that text box through client side. This textbox is disabled but I can see value getting updated in textbox on grid. When I  click save and loop through data items of grid, value for that textbox is empty.

 <Columns>     
               <telerik:GridTemplateColumn HeaderText="Amount" UniqueName="Amount">
                    <ItemTemplate>
                        <asp:textbox ID="txtamount" runat="server" enabled="false" >  </asp:textbox>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>

Is there any other alternative to this? I need to save this value for each row in grid.

Hi Harshit,

You faced the problem because the textbox is disabled. So one suggestion is just set the value of TextBox in a HiddenField and access the HiddenField value at server postback. Here is the code.

JavaScript:

<script type="text/javascript" language="javascript">
    function test(id)
{
    var grid = $find(id);
    var tableView = grid.get_masterTableView();
    var items = tableView.get_dataItems();
    for (var i = 0; i < items.length; i++)
    {
      var rowValues = items[i];
      var Textvalue = rowValues.findElement("TextBox1");
      var Hiddentext = rowValues.findElement("HiddenField1");
      Textvalue.value = "dfsd";
      Hiddentext .value = Textvalue.value;

    }
}
</script>

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       Button1.Attributes.Add("onclick", "test('" + RadGrid1.ClientID + "');return false");
   }
   protected void Button2_Click(object sender, EventArgs e)
   {
       foreach (GridDataItem item1 in RadGrid1.Items)
       {
           GridDataItem item = (GridDataItem)item1;
           HiddenField hidden1= (HiddenField)item.FindControl("HiddenField1");
           string hiddentext= hidden1.Value;
        }
   }

Thanks,
Princy.
