Prevent autosize on post-back

[ToltingColtAcres]

I am using autosize on several of my radwindows successfully.

There are a few windows where I would like to have the window autosized when it loads, but after the initial load, disable autosize on further postbacks.

I am running into a situation where I load a radgrid in a radwindow to display some data with filtering and sorting enabled. If the user specifies a filter criteria which yields no records, the radwindow resizes so small that they cannot "unfilter" because clicking the filter button again opens a list which disappears off the top and bottom of the 'resized' radwindow.

By using autosize when the window first opens, I get a properly sized window. I'd like to be able to disable autosize after the window is opened so on future postbacks the window will not resize.

I attempted to add this code to client-size scripting, but it had no effect. Can someone suggest a method by which I can accomplish this? Thanks, Mike.

​       function pageLoad() {
var oWnd = null;
if (window.radWindow)
oWnd = window.radWindow;
else
if (window.frameElement.radWindow)
oWnd = window.frameElement.radWindow;
if (oWnd) {
window.setTimeout(function () { oWnd.autoSize(false); oWnd.set_autoSize(false); }, 500);
            }
}

Hi,

Since you want autosizing only for the initial load I can suggest using the OnClientPageLoad event. Here are two ways you can have this done:
- no automatic autosizing, manually autosize only when needed, e.g.:

<telerik:RadWindow ID="RadWindow1" runat="server" AutoSize="false" OnClientPageLoad="OnClientPageLoad">
</telerik:RadWindow>
<script type="text/javascript">
    function OnClientPageLoad(wnd) {
        //with animation
        wnd.autoSize();
        //without animation:
        //wnd.autoSize(false);
    }
</script>

- OR, use autmatic autosizing, but disable it after the first time it autosizes:

<telerik:RadWindow ID="RadWindow1" runat="server" AutoSize="true" OnClientAutoSizeEnd="OnClientAutoSizeEnd">
</telerik:RadWindow>
<script type="text/javascript">
    function OnClientAutoSizeEnd(wnd) {
        wnd.set_autoSize(false);
    }
</script>
