RegisterClientScriptBlock is not working in ASCX page

Question

Hi Team,

My script is not working which I have written on Radbutton click for a particular condition in ASCX code behind page.

My Script

  function confirmSubmit(confirmMsg) {
            debugger;
            function callbackFunctionPerformStartProcessValidation(arg) {
                if (arg) {
                    debugger;
                    var argument = "Start Process";
                    $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest(argument);
                }
            }
            radconfirm(confirmMsg, callbackFunctionPerformStartProcessValidation, 300, 100, null, "Start Process Warning");
        }

Rad Button click

  string Tag = string.Empty;
                            string confirmMsg = string.Empty;
                            List<string> factTag = presenter.GetFactTagAssociated(projectId, DsId);
                            if (factTag.Count > 0)
                            {
                                confirmMsg += "The listed facts will be impacted.\n";
                               confirmMsg += "\n Do you want to continue?";
                            }
                                                     ScriptManager.RegisterClientScriptBlock
                            (this.Page,  this.GetType(), "confirmSubmit", "<script type='text/javascript'>confirmSubmit('" + confirmMsg + "')</" + "script>", false);
                                                     return;
                        }

After hitting the rad button, nothing is happening. It is not hitting the script too. Please let me know how to progress. It's really blocking me to progress.

Thanks in advance.

Hi rosalini,

From your description, you think the RegisterClientScriptBlock method was not working.

Actually,after debuging I found that when Rad Button clicked, the script was transfered, but it didn't show anything.

So I suggest you could debug your script code to find problem.

1.A possible reason for the RadAjaxManager not to be initialized properly is if it is declared before the script manager on the page.

2.Add a setTimeout function into your script code.

You could refer to the following links:
