try
{
switch(e.CommandName)
{
case "GotoDistrict":
GoToDistrict(e.Item,e.Item.ItemIndex);
break;
case "AddNewRecords":

private void AddNewRecords(DataGridItem item, int rowIndex)
{
try
{
RequiredFieldValidator stateNoRequired
=(RequiredFieldValidator)item.FindControl("stateNo_Requiredfieldvalidator");
RequiredFieldValidator stateDescRequired
=(RequiredFieldValidator)item.FindControl("stateDesc_Requiredfieldvalidator");
RangeValidator stateNoRange =
(RangeValidator)item.FindControl("stateNo_RangeValidator");
stateNoRequired.Enabled = true;
stateDescRequired.Enabled = true;
stateNoRange.Enabled = true;

TextBox stateNo_TextBox =
(TextBox)item.FindControl("addStateNo_TextBox");
TextBox stateName_TextBox =
(TextBox)item.FindControl("addStateDesc_TextBox");

string recordFound =objStateMaster.FindRec(stateNo_TextBox.Text
,stateName_TextBox.Text);

if (recordFound!="")
{
string msg = " already exists" ;
string space = " and ";
string stateNo="StateNo: ";
string stateDesc= "StateName: ";

Why not just use the RequiredFieldValidator controls and let them do all the
