I want to validate a WebCombo on the client side using a custom validator. Validating that a dropdown selection has been made after the "Go" button is selected. Which means that I want to load/activate the javascript function at the end of the last page event and before selecting the "Go" button.
JavaScript function:
function ComboCheck(sender, args){ var combo = igcmbo_getComboById('<%=wcPortName.ClientID %>').selectedIndex; if(selectedIndex == -1){ args.IsValid = false; } return args.IsValid; }
Validator:
<asp:CustomValidator id="validCustCombo" runat="server" CssClass="Text" ErrorMessage="Please make a selection in the dropdown!" ClientValidationFunction="ComboCheck"></asp:CustomValidator></TD>
Hi mamia77,
the above posts are about WebCombo, which is a different control, but i see you are referring to WebDropDown. What does get_selectedItemIndex return in your case ? do you select anything before submitting the form, or it stays with the default control values?
Thanks,
Angel

Not using an html button, but asp:Button
Hmmm, I have't used 1.1 in a long time.
Are you using an asp button or HTML Input button?
Try this
<input type="button" runat=server onclick="CheckCombo()" OnServerClick="RunYourServerSideFunction" />
This is what I have:
function CheckCombo(){
var SelectedRow = igcmbo_getComboById(comboGD).selectedIndex;
if(SelectedRow == -1) {
alert("Please Select Gaming Device") ;
return false;
}
return True
BUT I am running .NET 1.1 Thus the OnClick="CheckCombo" will not run?
