try to find out in the following way..

C#

protected void repOrder_OnItemCreated_drdFill(object sender, RepeaterItemEventArgs e)
{
  CheckBox chk = (CheckBox)e.Item.FindControl("chkbxOrder");
  chk.CheckedChanged += new EventHandler(CheckedChanged);
}

private void CheckedChanged(object sender, EventArgs e)
      {
        CheckBox cb = (CheckBox)sender;
        try
        {
            My Code
        }
        catch (Exception ex)
        {
        }
}

Hi

You may try like this

XML

<asp:CheckBox AutoPostBack="true" OnCheckedChanged="chkOpt_Changed" itemId='<%# Container.ItemIndex %>'  ID="chkOpt" runat="server" Text='<%# Eval("Name") %>'  />

.

If you want to access the row where the checkbox included then one way is using the custom attribute as I shown above the ItemId. Other option is through the Parent property.

For example in the check changed event

C#

protected void chkOpt_Changed(object sender, EventArgs e)
 {
     CheckBox chk = (CheckBox)sender;
     //get datalist row id from the custom attribute
     int rowId = Convert.ToInt32(chk.Attributes["itemId"]);

     //get the parent gridview row id through parent hierarchy (in your markup hierarchy)
     GridViewRow row = (GridViewRow)chk.Parent.Parent.Parent.Parent;

     int parentGridRowIndex = row.RowIndex;


 }

Good luck
