Hello Mohamed,

I am not quite sure about the way you have designed your aspx. The following KB article discusses calling radalert from code behind.
Calling radalert from codebehind (all versions of RadWindow)

C#:

RadWindowManager1.RadAlert("RadAlert is called from the server", "Server RadAlert", "alertCallBackFn");

Another approach is to implement RadAlert using direct method. The predefined dialogs (radalert, radconfirm and radprompt) can be now called by using the new server methods RadAlert, RadConfirm  and RadPrompt of the RadWindowManager.
Window / Alert, Prompt, Confirm.

Thanks,
Shinu.

Thanks For Ur replay,

RadWindowManager1

that don't have radalert or RadConfirm.
doesn't contain definition for RadConfirm and no extension method RadConfirm accepting first argument of type using Telerik.Web.UI.RadWindowManager1;  could be found (are you missing a using directer or an assembly reference)

Thanks ,
Mohamed .

Hello Mohamed,

Hi Mohamed,

I am not sure what your scenario is, but it looks like you want to show an alert from the server-side. As the previous post suggested you can:

• use the RadWindowManager's methods, but for that you would first need to have a RadWindowManager on the page (or on the master page if the scenario is more complex). These methods are available since Q1 2011
• If you are using an earlier version I would suggest that you upgrade to the latest release. If that is not possible please refer to the previously suggested blog post on executing a JavaScript function from the server-side.
• If you are using AJAX you can use the ScriptManager's RegisterStartupScript() method.

If you are still experiencing difficulties please open a support ticket and send us detailed information on the issue you are having along with detailed reproduction steps and we will do our best to help.

All the best,

Hello Mohamed,

You need to capture the Item Command event and use one of the approaches recommended below.

For your convenience I created and attached a simple page that uses an image button click and a regular button click to initiate the ItemCommand event, but you can use your own custom logic for that. In the code-behind I chose to inject a JavaScript function that calls the RadAlert, but you can use any other method, too. Please note that you need a RadWindowManager on the page to be able to call a RadAlert, RadConfirm or RadPrompt.

All the best,

how i get the value from radconfirm message yes or no

js:
function confirmCallBackFn(arg) {
                debugger;
                if (arg == true) {
                    alert("If True");
                                        return  true;

                    alert("Else");
                    return false;
                }
            }


Thanks,

Hi Mohamed,

Your code seems correct to me - the value returned from the confirm dialog box is contained in the argument you pass to the callback function.

I tested it in the previous page and it is working correctly on my end. You can find attached my test page with the new modification applied. Please note that you need to make sure that the controls are loaded before trying to use them, hence the usage of the Sys.Application.Load event.

If that does not help you please open a formal support ticket and send us a sample project that displays your issue along with detailed explanations of the desired effect and the difficulties you are having with our controls. At the current state of affairs I am mostly guessing what your scenario and needs are and in order to be able to provide a more to the point answer I will need your code and a more detailed explanation of your issues.

Hello Mohamed,

One suggestion is to use RadAjaxManager and make the ajaxRequest and pass the argument.
Javascript:

function confirmCallBackFn(arg)
        {
            if (arg == true)
            {
                alert("confirm returned the following value: " + arg);
                var ajxmgr = $find("<%=RadAjaxManager1.ClientID%>");//AjaxManager1 is the AjaxManager on page
                ajxmgr.ajaxRequest(arg);
            }
                 . . . . . . .
    }

C#:

private void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    //code to handle the generic AJAX request
}

Also take a look at the following help article.
client-side API

Thanks,

Hello Mohamed,

The RadConfirm is a client-side object and thus uses JavaScript. This means that you cannot block the execution thread on the server while waiting for the response from the client.

What I would suggest is to split this method in two

1. inject the client-side script and get the result from the RadConfirm on the client side
2. depending on that result call a hidden button's server-side click event where you update the database (the second part of the current method)

You can pass the necessary values in hidden fields on the page, in the viewstate or as global variables or properties in the code-behind's class, this decision is up to the developer and depends on your custom scenario.

Here is a small example how to execute a server-side function from JavaScript:

<input type="button" id="btnHidden" style="display:none" runat="server" onserverclick="serverside_handler" />
<asp:Button ID="Button1" Text="call method" runat="server" OnClientClick="callMethod(); return false;" />
<asp:Label ID="Label1" Text="" runat="server" />

function callMethod()
{
    document.getElementById("<%=btnHidden.ClientID %>").click();
}

protected void serverside_handler(object sender, EventArgs e)
    {
        Label1.Text = "from code-behind";
    }
