Load On Demand Webservice - Notify when complete

When the RadTreeView is set to ExpandMode.WebService, is there a mechanism to know when a node.expand() client javascript call is completed (jQuery promise, ect)? I want to defer the OnNodeDrop postback event until an expand is completed. Thanks!

Disabling of a control within a RadAjaxPanel

Is there anything wrong with this scenario? (For a change this only seems to happen in Chrome, both from the server and when run in Visual Studio. IE and Firefox don't have this problem.)

This is a Dot Net 4.0 C# web app. I have a Master page with a RadAjaxPanel. The panel contains an asp:Repeater which functions as a menu at the top of the page. The repeater contains and item template using an asp:LinkButton. The link buttons all fire a single event handler.

In the page using this master page I have another RadAjaxPanel. This contains an assortment of RadComboBoxes and one RadMenu, just added.

If I change the setting of any of the RadComboBoxes or the RadMenu (if any SelectedIndexChanged event fires) the repeater link buttons are disabled. The click event does not fire. (Sometimes. It seems to be intermittent.) If I refresh the page the links work again.

Suggestions?

Format Grid Export in Excel

Hello,

I am currently exporting my grid using the grid.MasterTableView.ExportToExcel() method. I am looking to format the outputted excel spreadsheet. I have read that this is possible using HTML/CSS-based formatting, but I would prefer not to change my current implementation of export. Would someone be able to provide an up-to-date example on how to format the excel export when using ExportToExcel()?

Thanks,
Matt

RadAsyncUpload is duplicated into 2 control when put into RadGrid

Dear Supporters !

Have a nice day.

Currently, I have using RadControl for ASP.NET to develop any systems.

I have used RadAsyncUpload control in RadGrid. No problems.

However, when RadAsyncUpload control in RadGrid, it it duplicated into 2 controls that the same in EditMode (Insert and Upload mode).

+ The first control: after select files, these files are not displayed. (I think this no right)

+ The second control: it is OK.

More defails about designer screen and actual problem screen is stored in attachment files.

Thanks in advanced !

Isolated Control for Html

HI Telerik

I have several large controls showing HTML data on a page. Problem is that html in one control is affecting other controls.

Is there any control that I can use to keep the HTML isolated for each control, so that it doesn't affect the other controls at all..

Thanks in advance.

DataBind not working

I have a control which is a grid, and has child controls of 2 tabs (which one control is a view, the other a grid).

If I change selected rows on the parent, the view refreshes fine by me calling child1.DataBind(). If I try child2.DataBind() the even isn't called. Why is that working for the view and not the grid?
