RadConfirm not Initializing on click of 'save' Button

[Usman]

I have two RadButtons on a page, 'save' and 'save and exit' (see attachment..). When I click on the 'save and exit' button,  I get the expected behavior however when I click on the 'save' button, the functionality dose not work. It is strange because although the buttons do the exact same thing except that 'save and exit' redirects the user to a different page. 

Why is the confirmation window not showing when I hit the save button?

Please advice

Thank you

JavaScript:

function ShowMessageAndRedirect() {
                var oWnd = radalert('<%= alertsave %>', 330, 150, '<%= alertHead %>');
                oWnd.add_close(OnSave);
            }
function ShowMessage() {
                var oWnd = radalert('<%= alertsave %>', 330, 150, '<%= alertHead %>');
                oWnd.add_close(OnSaveAndRedirectToSamePage);
            }

ASPX

<telerik:RadButton runat="server" ID="uxSaveExit"  ValidationGroup="AddProduct" OnClick="Save_Click" Text="Save and Exit" Width="90px" TabIndex="9">
        </telerik:RadButton>

        <telerik:RadButton runat="server" ID="uxSave" ValidationGroup="AddProduct" OnClick="Save_Click" Text="Save" Width="90px" TabIndex="10">
        </telerik:RadButton>



ASPX.CS

if (Model.IsSavedOrUpdatedSuccess)
            {
                if (((RadButton)(button)).Text == "Save and Exit")
                {
                    PersistSearch();
                    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "", "ShowMessageAndRedirect(); ", true);
                }
                else if (((RadButton)(button)).Text == "Save")
                {
                    PersistSearch();
                    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "", "ShowMessage(); ", true);
                    Response.Redirect("AddProduct.aspx?Mode=EDIT&Id=" + Model.Id);
                }
                else
                    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "", "ShowMessage();", true);
            }
            else
                RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "alert", "radalert('Product failed to add', 370, 150, '" + FortegraResource.MessageHead + "');", true);
        }

Hi Usman,

The Response.Redirect call changes the HTTP header so the script is not registered at all, you can easily confirm this by adding a blocking browser alert that you will never see:

else if (((RadButton)(button)).Text == "Save")
{
    //PersistSearch();
    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "", "alert();ShowMessage(); ", true);
    Response.Redirect("AddProduct.aspx?Mode=EDIT&Id="/* + Model.Id*/);
}

I am attaching a sample page with some more ideas and explanations in the comments so you can use it as base for implementing this in your project.

Perhaps the easiest approach is to redirect in the callback function of the RadAlert via JavaScript.
