Here is how my grid layout looks like. I want to access grid rowindex of grid row when I click checkbox within dropdown in grid. How can I achieve this?
 
Thanks

Hello Harshit,

Try the following code snippet to access rowindex in Combobox ItemTemplate.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
   {
     GridDataItem item = (GridDataItem)e.Item;
     RadComboBox combob1 = (RadComboBox)item.FindControl("ddlSupportUsed");
     CheckBox chk1 = (CheckBox)combob1.Items[0].FindControl("chk1");
     chk1.Attributes.Add("onclick", "clickEvent(" + item.ItemIndex + ")");
   }
}

JS:

<script type="text/javascript">
function clickEvent(index)
{
  alert(index);
}
</script>

Thanks,
Princy.
