The first time I load a usercontrol with a RadEditor in it, it looks like garbage.

I recently upgraded from 2009.2.713.35 to 2009.2.826.35 and now I am noticing extremely weird behavior with the RadEditor that wasn't present in the previous version.

Essentially I have a three panel layout on my page. The left panel contains a tree list and the middle panel dynamically loads a usercontrol when I click on a tree node. This works perfectly.

My problem is that the very first time I click on a node that loads a usercontrol containing a RadEditor, the editor is completely deformed - buttons are there, but not aligned correctly and missing labels. The editing surface panel is enormous and everything seems all over the place.

However, if I click on another node that uses the same usercontrol, then the editor appears exactly how I would assume it would. In fact, it appears to work perfectly from then on.

It seems that this is due to me using a relative width in the control (99%) because once I changed this setting to a flat pixel width, I haven't been able to reproduce the problem (Yet).

How did this happen between versions? Is this a known problem? Is there a way I can still have relative widths on this control?

Rename a Directory

Hi, I am getting an error when I try to rename a directory in the File Explorer. To reproduce this error I right-click the item in either the treeview or gridview, change the name, and either hit enter or click somewhere else on the screen to make the changes. When I hit enter the following error appears on my screen. This error only appears when I am renaming a directory, it doesn't happen when I am renaming a file.

System Error: System.ArgumentOutOfRangeException: Length cannot be less than zero.

Dynamically created RadDockZone layout

Hi

I need to be able to create a dynamic layout of RadDockZones and RadDocks.

In my attached pictures I have 2 examples of layouts I want to create where the different colors represent different DockZones.

They must be dynamic so I can load and save the layout on init. I also have to have the layout resizable to its container.

Is there a way to arrange RadDockZones to solve this problem.

I've tried many ways. For example to create a layout of tables created dynamic. Then attach a zone to each <td> using javascript. It work kind off but not really the way I want it to work.

Does anyone have an idea or example that can fix this problem?

RadTreeview in radcombo box is causing three scrollbars

Hello,

I have an instance when I am using a treeview inside a combobox, and when I open up a number of nodes I get a vertical scrollbar which is fine, however, when I open up more and more nodes, i get a horizontal scrollbar and then when I scroll to the right there is an additional vertical scrollbar. So I have a horizontal scrollbar and two vertical scrollbars. Once I hover over the tree, the horizontal and one of the vertical bars does go away, but I would like it so that I do not get the extra scroll bars at all. I believe the first vertical scroll bar belongs to the combobox and the horizontal and extra vertical belong to the treeview. Does anyone have any suggestions on how to keep only the one vertical scrollbar.

Thank you

Grid ajax filter issue

Hi,

We are using rad grid within our project.we have implemented filters within this grid as specified by telerik.
These filters work perfectly when postback occurs on click of apply filter.
But we wanted this functionality to work on ajax basis.

So we added radAjaxpanel and radScript Manager within the user control.

But when we add these pannels error keeps coming up relating to radAjaxpanel.

Can anyone let me know how this can be achieved that full functionality starts working on ajax basis.As happens with adding update panel.

Do let me know what all changes are required?

Thanks.
Amit

Self Referencing Hierarchy On Demand Load

Telerik,

I tried your demo of the self referencing hierarchical grid and just changed removed both
HierarchyLoadMode="Client"
<ClientSettings AllowExpandCollapse="true" />

To be able to load the grid on demand server side (default mode).
This is breaking the grid (no expand buttons anymore).

Is it possible to expand a self referencing hierarchical grid on demand on the server side ?

Thanks,
Pavan.

Drag & Drop did not work in User Control

Hello,

I'm trying to do drag and drop with the RadGrid, it works find when I run the sample code in an .aspx page, but when I use the same code in the .ascx user control, it didn't work. I found out it's because the e.DestDataItem = nothing. Is there something else I need to do? Thanks.
