I would suggest to use the approach shown below:

I tried OnClientClicking and OnClientClick...no luck.
Any ideas? Thanks!!!
function
ShowConfirm(clickedButton) {
var reqFiewldVal = document.getElementById("reqClubName");
ValidatorValidate(reqFiewldVal);
if (reqFiewldVal.isvalid) {
function callBackFn(arg) {
if (arg == true) {
__doPostBack(clickedButton.name,
"");
}
}
var text = "Are you sure you want to create this new Club?";
radconfirm(text, callBackFunction, 350, 100,
null, "Add New Club");
}
}
<
asp:RequiredFieldValidator ValidationGroup="grpClub" runat="server" ErrorMessage="Club/Activity Name is required" ID="reqClubName" ControlToValidate="txtClubName" Display="None"></asp:RequiredFieldValidator>
<
telerik:RadButton Font-Size="12" ID="btnUpload" runat="server" Text="Upload" Skin="Black" CausesValidation="true" ValidationGroup="grpClub" OnClientClicking="ShowConfirm(this); return false; ">
<Icon PrimaryIconCssClass="rbUpload" PrimaryIconLeft="4" PrimaryIconTop="4"/>
</telerik:RadButton>
There are several issue with the provided code:
1) the handler for the RadButton is attached by passing just the function name as an argument, not like for the regular asp button
2) to cancel the postback you need to call its args.set_cancel(true) command, not return false;
3) to perform the postback you could call a programmatic click on the RadButton via its click() method
4) the name of the callback function is not correct (it does not match the one declared in the radconfirm call)
Here follows the code that works correctly on my end:
function ShowConfirm(clickedButton, args) { args.set_cancel(true); var reqFiewldVal = document.getElementById("reqClubName"); ValidatorValidate(reqFiewldVal); if (reqFiewldVal.isvalid) { function callBackFunction(arg) { if (arg == true) { clickedButton.click(); } } var text = "Are you sure you want to create this new Club?"; radconfirm(text, callBackFunction, 350, 100, null, "Add New Club"); } }and the markup:
<asp:TextBox ID="txtClubName" runat="server" /> <asp:RequiredFieldValidator ValidationGroup="grpClub" runat="server" ErrorMessage="Club/Activity Name is required" ID="reqClubName" ControlToValidate="txtClubName" Display="None"></asp:RequiredFieldValidator> <telerik:RadButton Font-Size="12" ID="btnUpload" runat="server" Text="Upload" Skin="Black" CausesValidation="true" ValidationGroup="grpClub" OnClientClicking="ShowConfirm"> <Icon PrimaryIconCssClass="rbUpload" PrimaryIconLeft="4" PrimaryIconTop="4" /> </telerik:RadButton> <telerik:RadWindowManager runat="server" ID="RadWindowManager1"></telerik:RadWindowManager>An example of a confirmation used with a RadButton is available in the following online demo: http://demos.telerik.com/aspnet-ajax/button/examples/confirm/defaultcs.aspx.
I hope the information above will help you successfully implement the desired functionality.
On a side note - I would advise providing some information to the user why the validation failed and the button seems to be non-functional.

Shouldnt the validator show the err msg if it is not valid?
What I did was I put a radconfirm in the 'else' statement of IsValid().
Whats funny is that AFTER the radwindow shows, the validator says 'Club name required' as it should but when I remove the radconfirm from the else...it doesnt show.
What should I do in the else statement to make the validator show the error (i dont want to show a radconfirm in this case, it was just a test to see what happened)
Thanks so much for the help, greatly appreciated!!!!
if
(reqFiewldVal.isvalid) {
function callBackFunction(arg) {
if (arg == true) {
clickedButton.click();
}
}
var text = "Are you sure you want to create this new Club?";
radconfirm(text, callBackFunction, 350, 100,
null, "Add New Club");
}
else
{
var text = "Please enter Club name.";
radconfirm(text, callBackFunction, 350, 100,
null, "Add New Club");
}
I would recommend that you start by examining this help article: http://www.telerik.com/help/aspnet-ajax/radbutton-validation-with-postback-confirm.html.
Note the Display=None property of your RequiredFiedValidator - this is the main reason why you generally have no error message.
Also, if I have understood your scenario correctly the radconfirm should appear only if the validation is successful and it should confirm if the user really wants to submit the page. He/she would not be able to submit it if the validation did not pass, therefore the if() statement (where the confirm is called) should be entered only if the validation passed.
That being said I attached the modified page that exhibits the described behavior: http://screencast.com/t/RUAurZtRPrxf. I hope it helps you implement the desired functionality. Note that I have placed the RequiredFieldValidator after the RadButton, as otherwise the change of display of the error message will move the RadButton and will cause issues with the user clicking.
On a side note - the CausesValidation property of the RadButton is not necessary - it defaults to true and besides, the ValidationGroup is set.
