Hello,

I am trying to build RadWindow functionality into a user control.

The user control contains the mark up for the radwindowmanager and everything is working in that I can get the window to open and apply all the properties (skin, size, position, behaviours etc) I need.

However also want to add an OnClientClose option to refresh the underlying page.

To do this I am envoking the following script from the page that opened the radwindow:

function GetRadWindow() {
var oWindow = null;

if (window.radWindow) oWindow = window.radWindow;

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;

return oWindow;

}

but this function always return a "null or not an object error".
Any advice would be much appreciated.

Listbox row number

Hi All,

I want to show row number for each item in rad listbox control.
After binding row number if user drag and drop any item it should rebind.

For example
Initially it should show row number as shown in below table.

Row Number	Image Id
1	111
2	222

When user change order of items using drag and drop, it should not change Row number value.

Row Number	Image Id
1	222
2	111

Is it possible to handle at client side, page should not get posted?

Thanks,
Dipal

RadEditor on IE text doesn't appear in design mode

Hello,
I have a problem with RadEditor. when I open it in FF, all is well. The problem starts when I open the web page using IE. All normal when I typed in the first line. But after I press enter to write in the second row, any text I type does not appear. This happen only in design and Preview Mode.

My further investigation, I found RadEditor runs fine if I remove the DocType from the master page: <! DOCTYPE html PUBLIC "- / / W3C / / DTD XHTML 1.0 Transitional / / EN" "http://www.w3.org / TR/xhtml1/DTD/xhtml1-transitional.dtd ">

But all other elements becoming a mess. Until now I can't find the same problem on this forums.
(I'm using FF 16.0.2, IE 9, Telerik.Web.UI version 2012.2.912.40)

Anyone know how to solve this?

Thanks,

RadSkinManager and RadToolTipManager

How do I apply a skin to tooltips produced using RadToolTipManager via the RadSkinManager?

It appears RadToolTipManager is not an option in the ControlsToApplySkin property (see snippet below).

<telerik:RadSkinManager ID="rsm" runat="server" ShowChooser="false">
   <TargetControls>
       <telerik:TargetControl ControlsToApplySkin="RadToolTip" Skin="Sunset" />
   </TargetControls>
</telerik:RadSkinManager>

I kinda have a problem because i would like to set the header data (titles) using the code behind.

AJAX Combobox Load-on-Demand with CustomText AND SelectedValue

We have been trying to use a combination of features of the RadComboBox. We want to use Load-on-Demand with CustomText AND also set/persist a SelectedValue, with a large number of records. We have encountered a couple issues that prevent us from accomplishing our goal.

The online demo ( http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx ) narrowly avoids one of the major issues we have encountered with the suggested implementation of load-on-demand. The online demo loads just enough records per request (10) that no matter what custom text is entered, there is never more than one request worth of filtered items to load. We often need multiple requests to load all of the matching/filtered items for the custom text, but the demonstrated method reverts to loading unfiltered items after the first request. We tried working around this issue ourselves, but then ran into another quirk of the load-on-demand mechanism.

The demonstrated method seems to only be feasible in the context of a single pass questionaire. Our application requires users be able to view and edit previous selections in fields with load-on-demand enabled. We are able to set a selected value, but then load-on-demand breaks. Every time the user clicks the load more results button, another duplicate of the selected value is added to the list. We tried various workarounds without success. We cannot distinguish between the first request (showing the selected value) and subsequent requests (showing filtered or unfiltered items based on the custom text).

We need to accomplish the following with the RadComboBox:

Load-on-demand (we have very large lists of items to select from in our application)
Custom text/filter (loading multiple pages of items isn't enough, we need to filter the list)
Selected value (on returning to the page, the user needs to be able to see what they selected previously as well as select a new value)

We are very close to having all three features working together, but are missing a piece. When the user opens the combobox, sees the selected value listed as the only item, and clicks the load more results button, we need to load unfiltered items instead of filtered items. We can always load the unfiltered items, but then we have the opposite problem: the custom text is never used to get a filtered list of items. This is the last obstacle to overcome in order to get load-on-demand working in our application the way it should (we think) by design.
