Question

How can i get row index of the grid view whose child control is doing post back. I know the way of getting control causing post back and finding its parent container which returns grid view row and then find its index. I want this in a RowDataBound event to check selectedrow index and formatting the same. Is there any other property or settings which directly emits selected index of the grid view on any child control post back

Edit:

For example if there is a dropdownlist in a row and there are certain rows in a gridview. Then i want gridview rowindex where postback happens due to that dropdowlist in the gridview row.

You can get the index of the row in RowDataBound via the RowIndex property:

protected void gridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int index = e.Row.RowIndex;
    }
}

You can get the index of any child control in a GridView via

• childControl.NamingContainer =>
• GridViewRow =>
• RowIndex

for example in a DropDownList.SelectedIndexChanged event:

protected void DropDownList1_SelectedIndexChanged(Object sender, EventArgs e)
{
    DropDownList ddl = (DropDownList) sender;
    GridViewRow row  = (GridViewRow)  ddl.NamingContainer;
    int index        = row.RowIndex;
}

Finally: since you’ve mentioned ” to check selectedrow index”, if you’re actually looking for the selected row index of the GridView itself, there’s a property just for this:

• GridView.SelectedIndex Property
