Radprompt - Get clicked button

[Laz]

Hi to all,

it is possible to get the clicked button of a radprompt?

I try to check if the OK Button is clicked and the Textbox left blank to call another Alert with an error message.

My problem is that when i clicked the CANCEL Button i get the NULL Value and when i left blank the textbox and click the OK Button then i also geht the NULL Value.

    <script type="text/javascript">

        function openPrompt(TitleText, Text, IText, IIndex) {
            document.getElementById("<%= hdnIIndex.ClientID %>").value = IIndex;
            radprompt(Text + '<br style="clear:both" /><strong>' + IText + '</strong>', promptCallBackFn, 330, 100, null, TitleText, null);
        }

        function promptCallBackFn(arg) {

            document.getElementById("<%= hdnText.ClientID %>").value = arg;
            if (arg != null && arg != '') {
                document.getElementById("Refresh").click();
            }
            else {
                radalert('You have clicked OK, but the text is blank', 330, 100, 'Error Msg'); return false;
            }
        }

    </script>

Hi Laz,

Please make sure that you are using a recent version of the control. RadWindow's radprompt dialog will return empty string if the textfield is left blank and the user hits the OK button.

function openPrompt()
{

    radprompt("Please provide value", callbackFn);
}

function callbackFn(arg)
{
    if(arg == "")
    {
        radalert("please provide valid value");
    }
}

I would like to know of how to get this  ("<%= hdnIIndex.ClientID %>")  ? I got error for that.

Hi Qing,

Try wrapping the client-script logic containing server tags into RadCodeBlock and see if this will resolve the problem:

https://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/radcodeblock-and-radscriptblock#radcodeblock

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        ...
    </script>
</telerik:RadCodeBlock>
