Failed to load viewstate in Rad window

This is how I load rad window

<script type="text/javascript">

function openRadWin(code, bookingdate, category) {

radopen("MyPage.aspx", "RadWindow1");

}

</script>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true"

VisibleStatusbar="false">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="400px"

Height="400px" Title="Telerik RadWindow" Behaviors="Default" >

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

The rad window pop-up and it show "MyPage.aspx" correctly . But , In "MyPage.aspx" , I have a RadGrid with "AllowFilteringByColumn="true" " . When I filter RadGrid , it shows me the error

Server Error in '/' Application.

Failed to load viewstate.  The control tree into which viewstate 

is being loaded must match the control tree that was used to save 

viewstate during the previous request.  For example, when adding 

controls dynamically, the controls added during a post-back must 

match the type and position of the controls added during the initial request.

How can I fix it ?

RadToolTip on a ModalPopup

Has anyone had any success with displaying a RadToolTip on the ModalPopupExtender of the AjaxControlToolkit?

In IE, it works as expected, but in Firefox the RadToolTip consistently displays undernead the modal popup.

I have tried to set the z-index on the RadToolTip explicitly to be higher than the modalpopup's script, but this doesn't do the job.

OnClick not firing in Firefox... under specific conditions

I have a page that runs in a RadWindow. There is a RadButton on this page, that has both an OnClientClicking event (which sets a Tab control index) and an OnClick event which fires logic on the server through the RadAjaxManager.

In Chrome and IE, the OnClientClicking fires, then the OnClick makes the postback.

On Firefox however, the OnClientClicking is the end of the line. OnClick does not get fired.

If I run this same page directly, instead of from the RadWindow - it works as expected in FireFox...

This is my OnClientClicking routine - pretty simple - I can't see why Firefox would stop. I get no errors in the Console, etc...

function setResultsTab(sender, args)
{
    var tabStrip = $find('<%=tabCriteria.ClientID%>');
    var tab = tabStrip.findTabByValue('1');
    tab.select();
}

<telerik:RadButton ID="bAdvancedSearch" runat="server" Text="Search" SkinID="defaultButtonLargeSearch"

OnClick="click_AdvancedSearch" meta:resourcekey="bAdvancedSearchResource2" OnClientClicking="setResultsTab"/>

Allow Keyboard navigation but execute postback in rowclick(mouse click) or Enter key

<ClientSettings AllowKeyboardNavigation="true" EnablePostBackOnRowClick="true" >

<ClientEvents />

<KeyboardNavigationSettings EnableKeyboardShortcuts="true" />

<Selecting AllowRowSelect="true" />

</ClientSettings>

Good day there seems to be a problem with my code, I know the keyboard navigation works(browsing through the grid list using up and down keys) but the mouseclick doesnt work(not executing the postback). I have a function that executes on postback. and also can I change the enter keys function by executing my function instead of editing the data.

[Solved] Full postback triggered on clicking command item buttons

Hi,

I have an issue related to the post back triggered by the command items of radgrid.

Scenario is I have a web page that contains two rad grids they both have their command item template inside the rad-toolbar.

both grids have Add, update, delete on their command item templates whose visibility are decided by the no of record chosen from the respective grid.

Problem -
When I click say one command item from radgrid1 than it forces the complete page post-back and due to this the command item visibility
on radgrid 2 gets reset .
So is there any way that both grids should not disturb the each other say command items visibility.

Please help

thanks
