Error executing Javacsript in another pane (Q3 2009)

Just upgraded from Q2 2009 to Q3 2009(.net35) and I get this error now when I try to execute a javascript in another pane. This works in Q2 2009.   In IE7, the error is Object doesn't support this property or function. Similar error in FF. I have two versions of the script should work. This script is called from the pane OnclientResized event like so(OnClientResized="LeftResize"). Here are the scripts:

function LeftResize()
        {

        var splitter = $find("<%= NestedSplitter.ClientID %>");
        var pane = splitter.getPaneById("<%= lframe.ClientID %>");
        var myiframe = pane.getExtContentElement();
        var mycontentWindow = myiframe.contentWindow;

        try {
           mycontentWindow.SizeMe();

           }
        catch (e) {
            alert('Error calling content resize. Please report this error to Network Automation. Error is: ' + e.message);
            }

            }

function LeftResizeV2() {
                var pane = $find("<%= lframe.ClientID %>");
                pane.getExtContentElement().contentWindow.SizeMe();
            }

they will call this js on the target page in Q2:

function SizeMe()
    {

    }

Drag/Drop with Tabs

I have the RadTabStrip control setup with 5 tabs and inside each tab is a RadGrid. The tabs indicate a status for the items in the grid and it's the same user control in all 5 places. I'm trying to find a way to use the grid's drag/drop feature to drag a row item to a tab which would allow me to capture it, change the status of the item and rebind the source grid where the item came from (effectively removing it from this list). The MultiPage and Tab controls are setup using a RadAjaxManager so it's 100% callbacks with no postbacks.

Is this possible with Q2 2009?

RadEditorNodeInspector hide classname

Hi,

I am using the latest version of the RadEditor for Ajax (0619), i want to use the RadEditorNodeInspector, but i dont want to expose the classname, tooltip, target, hyperlink manager etc. I just want to expose only the URL, so the user can change it; also i want to increase the size of the URL box. Is this possible, if yes, how.

Thanks,

Change Page Size

We're trying to keep track of a users preferred page size and set that at page load when they return to our site. This works fine when they set the page size to an amount less than the current number of records. But when a user has 25 records and sets the page size to 50, it sets it to 25. 50 doesn't get passed to the code behind PageSizeChanged method, instead 25 does. I've looked into the control and the JS on the change button is:
var cpsi = document.getElementById("grdResults__ChangePageSizeTextBox"); if ( cpsi.value > 12 || cpsi.value == 12){cpsi.value=Math.min(12,12);return false;};

Clearly this amount is being adjusted client side if it is greater than the current record count. The question is can I turn this off? It's a pain if the user tries to set the max to 50, it gets set to 25, then they add a new record and it's on the next page.

Thanks for your help.

Problem in using custom skin

Hi Telerik,

We are using ajax rad tree view in our project with the custom skin styles. We found that the background-position values in the styles classes: rtPlus, rtMinuns are replacing with different values. Due to that the expand and collapse images in the tree view nodes are disappearing on mouse over.

Note: But the same skin is working fine if we use it on another project.

Please suggest me to apply only skin styles.

Thanks in advance,
Balaji Velasiri
