Get the RowData of the Selected Row

[Yash]

I have a RadGrid with a GridClientSelectColumn and a bunch of GridBoundColumn.
Databinding is going on fine.
But, when click on the checkbox of the GridClientSelectColumn, I want to get the data of that particular Row. How will I do it??

What I have attempted is using the OnSelectedIndexChanged event. But the problem I am facing is, when ever I do a radGrid1.SelectedItems[0], it gives me OutofBounds error. I did EnablePostBackOnRowClick=true, in clientsettings, allowrowselect=true . The event is also being hit successfully, but I am not able get the selectedrows this way. Is there any other way to accomplish what I want to do??

Once again, I want to get the data of a particular Row which is selected. How can I do it??

Thanks in advance.

Hello Yash,

Try the following code snippet in SelectedIndexChanged event to get the contents of selected row.

C#:

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
{
      foreach (GridDataItem item in RadGrid1.SelectedItems)
      {
            string txt1 = item["ColumnUniqueName"].Text;
      }
}

Thanks,
Princy.

Hi Princy, I see you giving this answer for lot of questions relating the Selected Row. Let me put my radgrid markup and the code behind that I am using to get row information.

<telerik:radgrid runat="server" ID="rgCOR"

            AutoGenerateColumns="False" CellSpacing="0" GridLines="None"

            AllowSorting="True"

            <HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

             

        </telerik:radgrid>

protected void rgCOR_SelectedIndexChanged(object sender, EventArgs e)

    {

    foreach (GridDataItem item in rgCOR.SelectedItems)

      {

            string ss = item["ID"].Text;//this is never hit. even if you have 100 rows selected


      }

    }

 

protected void rgCOR_ItemCommand(object sender, GridCommandEventArgs e)

    {

    if (e.CommandName == "RowClick")

        {

             

        GridDataItem temp = (GridDataItem)e.Item;

             

        if (e.Item.Selected == false)
             //this condition is always true even if you
             //select a row or un-select a  row

            {

            e.Item.Selected = true;


            }

        }

    }

Now, all I want is, data of the Row I select. I should not bother about any previously selected rows. I hope I am clear in this. The code snippet you gave is not working for me. I dont know why. Please see my mark up if I have messed up something. I have included some comments in the code behind which tells what problems I am facing.

regards
Yash

Hi Yash,

Do you attach the rgCOR_SelectedIndexChanged handler dynamically to the OnSelectedIndexChanged event of the grid. Because I don't see in the declaration of your grid. If you attach it dynamically make sure to do it on Page_Init event.
If you forgot to attach it, please add OnSelectedIndexChanged="rgCOR_SelectedIndexChanged" to the declaration of the grid and let me know if still not work properly.

Best wishes,
Vasil

Thanks for the help, but that was not the solution. The table was getting rebound after my logic is executed. Thanks for the help. and for my requirement, "ItemCommand" event works much better. SelectIndexChanged doesnt work for my kind of requirement.
