How to close the parent window from its child?

ajax, asp.net, c#, radwindow, telerik

Solution

protected void Button1_Click(object sender, EventArgs e)
{
    ((RadAjaxManager)this.Parent.FindControl("RadAjaxManager1")).ResponseScripts.Add("CloseModal();");

    RadAjaxManager1.ResponseScripts.Add("CloseModal();");
}

If the `CloseModal()` event is firing correctly, you should be able to call `window.close()` within it. The RadWindows only exist in the context of the parent window so you should still be able to call `window.close()` which will close each window that's open.

Edit: although a bit off-topic, this link from Telerik shows you how to get a handle on the parent window from a RadWindow. Then you can call the close method client side to close the browser window (page1.aspx) which will close all subsequent RadWindows.

From this link:

The main difference between RadWindow and browser's popup is that just like any other DHTML element, RadWindow exists only in the context of the page in which it is created. It cannot leave the boundaries of the browser window.

Problem

I have the following case: I have a gridview on my page : ``` page1.aspx ``` I open another page(`page2.aspx`) through that gridview in a rad window then after that,through some button on `page2.aspx` i open the last page (`page3.aspx`) in a `rad window` also. all these steps are performed through server side code : ``` protected void OpenNewWindow(string url, int width, int height, int mode) { RadWindow newWindow = new RadWindow(); newWindow.NavigateUrl = url; newWindow.VisibleOnPageLoad = true; newWindow.KeepInScreenBounds = true; newWindow.Skin = "Metro"; if (width > 0) { newWindow.Width = width; } if (height > 0) { newWindow.Height = height; } newWindow.VisibleStatusbar = false; if (mode == 0) { { } //newWindow.OnClientClose = "OnChildWindowClosed"; newWindow.DestroyOnClose = true; newWindow.InitialBehaviors = WindowBehaviors.Maximize; } RadWindowManager1.Windows.Add(newWindow); } ``` What i want to do is : when clicking on a specific button on my (`page3.aspx`) close it and its parent `page2.aspx`. How to do this (server side)? I try this :but it just closes the child `page3.aspx` i want to close the parent `page2.aspx` also ?! ``` protected void Button1_Click(object sender, EventArgs e) { ((RadAjaxManager)this.Parent.FindControl("RadAjaxManager1")).ResponseScripts.Add("CloseModal();"); RadAjaxManager1.ResponseScripts.Add("CloseModal();"); } ```
