Close and refresh without postback on the parent

[Deniz Torlak]

Hi there,

I have a situation and actually I can explain it using one of your examples. 
I am using a page like this;
http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultcs.aspx

My code uses the contenttemplate version and there is a small form with in the radwindow. Then the save button is clicked it does a postback from codebehind like in your example. What I want to do is when I click the save button I want to call a function in the parent page which runs some code and updates one of the 3 grids on the page and I want to do this using ajax without refreshing the whole parent page. 

However even if I use the ajaxmanager or the ajaxpanel I can open the radwindow via ajax but the save button always does a postback and make the whole parent page refresh (behaves like in your example code)

How can I do the postback via ajax from the radwindow (using contenttemplate) without refreshing the whole parent page?

thanks
Deniz

Hello,

Take a look into the following forum thread which discussed the same.

Thanks,

Ok I guess I am missing something here. I prepared a  very simple example that represents my core problem

OpenWindow button opens the rad window with ajax but when I click the update button in the radwindow it does a full postpack on the parent page instead just closing the radwindow doing an ajax update on the CurrentText textbox. 

so what am i doing wrong?

Here is aspx page code 

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPages/iMarina.master" AutoEventWireup="true" CodeFile="AjaxandWindow.aspx.cs" Inherits="Sayfalar_Test_AjaxandWindow" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

 

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

 

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

 

    <telerik:RadTextBox ID="CurrentText" runat="server"></telerik:RadTextBox>

    <telerik:RadButton ID="OpenWindow" runat="server" onclick="OpenWindow_Click" Text="Edit"></telerik:RadButton>

 

    <telerik:RadWindow ID="RadWindow1" runat="server">

        <ContentTemplate>

        <telerik:RadTextBox ID="UpdatedText" runat="server"></telerik:RadTextBox>

        <telerik:RadButton ID="Update" runat="server"  onclick="Update_Click" Text="Update"></telerik:RadButton>       

        </ContentTemplate>

    </telerik:RadWindow>

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

        <AjaxSettings>

            <telerik:AjaxSetting AjaxControlID="OpenWindow">

                <UpdatedControls>

                    <telerik:AjaxUpdatedControl ControlID="RadWindow1" LoadingPanelID="RadAjaxLoadingPanel1" />

                </UpdatedControls>

            </telerik:AjaxSetting>

            <telerik:AjaxSetting AjaxControlID="Update">

                <UpdatedControls>

                    <telerik:AjaxUpdatedControl ControlID="CurrentText" LoadingPanelID="RadAjaxLoadingPanel1" />

                </UpdatedControls>

            </telerik:AjaxSetting>

        </AjaxSettings>

    </telerik:RadAjaxManager>

    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" MinDisplayTime="5000">

    </telerik:RadAjaxLoadingPanel>

</asp:Content>


And here is the code behind:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Sayfalar_Test_AjaxandWindow : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void OpenWindow_Click(object sender, EventArgs e)
    {
        this.RadWindow1.VisibleOnPageLoad = true;
    }

    protected void Update_Click(object sender, EventArgs e)
    {
        this.RadWindow1.VisibleOnPageLoad = false;
        CurrentText.Text = UpdatedText.Text;
    }

}

Hello Deniz,

I am not sure exactly how you have set up your RadWIndows, but I advise you examine the following help article on properly using RadWindow with AJAX: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html. I also suggest you examine this one on the correct way to open it from the code-behind: http://www.telerik.com/help/aspnet-ajax/radwindow-troubleshooting-opening-from-server.html which, I believe, can reduce the number of the required AJAX settings. The same approach can be adopted for executing a script that will close the RadWindow. You may also find useful this article on calling functions from the RadWindow in case you are using the NavigateUrl: http://www.telerik.com/help/aspnet-ajax/window-programming-calling-functions.html. Similar approach is shown in this online demo as well.
