Any changes with my code will be great My Codes

Form_Load(){
DataGridViewComboBoxColumn^ ReligionClm = gcnew DataGridViewComboBoxColumn();
this->myDataGrid1->Columns->Remove("religion");
this->myDataGrid1->Columns->Insert(5, ReligionClm);
this->myDataGrid1->Columns[5]->Name = "religion";
}

System::Void MyDataGrid1_EditingControlShowing() {
ComboBox^ ComBox = dynamic_cast<ComboBox^>(e->Control);
ComBox->SelectedIndexChanged += gcnew EventHandler(this, &Form_Form1::EmpCmb_SelectedIndexChanged);
}

System::Void EmpCmb_SelectedIndexChanged() {
if (myDataGrid1->CurrentRow->Cells["religion"]->Value=="Add New Item"){
