I tried following code in cs file...not sure how to continue..
protected void DataGrid1_ItemC ommand(Object sender, DataGridCommand EventArgs
e)
{
CheckBox chkTrans = ((CheckBox)e.It em.FindControl( "chkTranslateEd it"));
if (chkTrans != null)
{
bool bChkTrans = chkTrans.Checke d;
if (bChkTrans == true)
{
TextBox txtExpire = ((TextBox)e.Ite m.FindControl(" txtDtExpire"));
if (txtExpire !=null)
{
if (txtExpire.Text .Trim() == "")
{
lblMessage.Text ="Textbox Empty";
e.Item.Attribut es.Add("onclick ","alert('p l enter dt expire');"); --
This doesnt seem to be right!!! because it doesnt fire at all...After
validation i need cursor to go to that textbox... PL HELP..

lblMessage.Text ="Textbox not avail";
}
}
}
}
