My page contains more than one dropdown list,in which some is mandatory fields,hence given required field validator.What i need is to include validation summarry,only if the datatable bound to DDL is empty,ie,only if the DDL contains no data to chose from.Ho to achieve this?
This is for your Knowledge:
<asp:panel ID="ErrorsPanel" runat="server" CssClass="ErrorSummary">
<asp:CustomValidator id="CustomValidator1" runat="server"
Display="None" EnableClientScript="False"></asp:CustomValidator>
<asp:ValidationSummary id="ErrorSummary" runat="server"
HeaderText="Errors occurred:"></asp:ValidationSummary>
</asp:panel>
Whenever you find the ddl is empty, you should execute this below code :
CustomValidator1.IsValid = False
CustomValidator1.ErrorMessage = "The DDL is Empty"
you can also use the Required field validator for the specific control.
Hope this helps...
