Get Checked Values from GridView Using Extension Methods
by azamsharp on 6/6/2008 8:17:02 PM
I was in a situation where I needed to get the checked rows out of the GridView control. So, this time I thought why not use extension methods to perform this task. So, I came up with the following methods.
public static class ExtensionMethods
{
public static GridViewRow[] GetCheckedRows(this GridView gv, string checkBoxId)
{
List<GridViewRow> checkedRows = new List<GridViewRow>();

foreach (GridViewRow row in gv.Rows)
{
CheckBox chk = row.FindControl(checkBoxId) as CheckBox;
if (chk == null) throw new Exception(String.Format("CheckBox ID {0} not found!",checkBoxId));

if (chk.Checked)
checkedRows.Add(row);
}

return checkedRows.ToArray<GridViewRow>();
}
Refactor it!
