}
if (string.IsNullOrEmpty(cbunit.Text))

}
hstbl.Add("@ReceivedQuantity", txtquantity.Text.Trim());
if (string.IsNullOrEmpty(cbcategory.Text))
{
errorProvider9.SetError(cbbrand, "Please enter Product Price");
hstbl.Add("@CategoryId", cbcategory.SelectedValue);
return;
}
else
{
errorProvider9.SetError(cbbrand, string.Empty);
}
if (string.IsNullOrEmpty(cblevel1.Text))
{
errorProvider10.SetError(cbbrand, "Please enter Product Price");
hstbl.Add("@SubCategoryId", cblevel1.SelectedValue);
return;
}
else
{
errorProvider10.SetError(cbbrand, string.Empty);
}
if (string.IsNullOrEmpty(cblevel2.Text))
{
errorProvider11.SetError(cbbrand, "Please enter Product Price");
hstbl.Add("@SubsSubCategoryId", cblevel2.SelectedValue);
return;
}

}
hstbl.Add("@WarehousePrice", txtwsprice.Text.Trim());
hstbl.Add("@ResalePrice", txtrsprice.Text.Trim());
hstbl.Add("@fprice", txtfsprice.Text.Trim());
hstbl.Add("@price", txtprice.Text.Trim());
hstbl.Add("@createdby", Global.UserID);
Int64 intidentity = DataAccessLayer.ExecuteCommand_RowsAffected("Product_Mst_sp", hstbl);
if (intidentity >= 0)

MessageBox.Show("Product Details Saved Sucessfully", "Product Alert");
