I have been working on this for two days and cannot get passed this error message when working with the RadFileExplorer.
I have read almost every post I can find on this topic.
The issue is after setting the viewpaths and uploadpaths, the RadFileExplorer displays the data just find. But when I click on the refresh button, I get the error "Invalid Characters in Folder Name". I also get this error If I try to programmatically set the path after a click event somewhere else on the page. 

Do I need to set the initial path attribute? Any value I set seems to result in the same error. Please help me find a fix for this. I am using version 2010.2.836.35, but also tried version 2010.3.1109.35

My code is very similar to the example posted at this link:

http://www.telerik.com/support/kb/aspnet-ajax/fileexplorer/physical-paths-and-different-content-types.aspx

Any help is appreciated.

I have also tried the fix recommend here: http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/change-initialpath-not-working.aspx

...but to no avail.....

Hi all,

I have a grid where I want to switch columns and rows, so the column header should be displayed lefthand:

Normal grid:

I want:


I've found some old postings from 2007 and 2009 recommending this demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/pivot/defaultvb.aspx but the postings are already 2 years old and I wonder whether this is now possible easier? I also need to have the filters but it seems with current demo it just creates one large table, removing all the advantages (filtering, sorting, etc.) which are offered by RadGrid normally.

Many thanks!

On my form all controls are in a asp panel. This panel is added to the RadAjaxManager in the UpdatedControls.  This panel contains a lot of textboxes that are validated with the jQuery validate plugin (bassistance.de). There is also a texbox that should be update form the server with a postback (the value comes from a webservice call). When the postback is done the whole main panel gets updated and my jQuery validation messages are gone. Is it possible just to update the one textbox and let the rest of the form as it is? The code sample is a test i can't get working like this.

Hi

I have one problem

In my grid I set pagesize =10

I added 11 records

It was showing in 2 pages.

When I removed 11th record from second page, It is not pointing to  first oage whihc has values.

It is showing 2nd page and saying that , there are no records to display.
Could you please help me to resolve this issue.

I really appreciate , if some one helps me regarding this.

Thanks
Usha

Could you please clarify us can we use aggregation for GridTemplateColumn in last Telerik version? Thanks.

We need some visual effects while dragging items from one grid to another. Specifically, we'd like the pointer to change to a plus sign when in a droppable area (but I've been told this isn't built in within a previous post), and we'd like to show a line before/after the grid items that we're dragging over to show where the record will be dropped to upon MouseUp. Is there any event to tap into that would allow this to happen? Or any other method to get this done?

I think what would be optimal is something like the OnClientDrag event that is part of the RadDock control. It doesn't look like the RadGrid has any similar events though.

Hi,

I have a problem with telerik control. If I use more different controls on page, last controls is not initialized. I try it with radwindow, radnotification, radgrid, radtoolbar, radtree, ...
See attachment.
If I reorder some control, is ok, but another is not initilized.
See last attachment

Thanks for answer.

With best regards
