Hi,
I am adding treeview to a listboxItem. I create a treeview and add nodes dynamically. It works fine but when I want to transfer the nodes to another listbox, i can't find the treeview in the listboxItem.controls collection.
How can I find the treeview in OnTransferring event.
Thanks,
Monika

Is it possible to change the color of individual items in a RadComboBox on the client side? Something like the following is what I mean (obviously this doesn't work or I wouldn't have a problem).
myCombo.get_items().getItem(0).get_attributes().setAttribute("style", "font-color:red;");
Thank you.
myCombo.get_items().getItem(0).get_attributes().setAttribute("style", "font-color:red;");
Thank you.

Hi,
in the Master I have a Rad menu, which gets the items from a siteMap-File
In the method radMenu_ItemClick I tried to get a reference to the RadGrid in the current Page. (I assume here that the correct page is currently loaded)
The idea is then to call ExportToExcel as a method of the referenced object. But the object is null!
What's wrong? What must I do to get a working reference to the RadGrid?
Thank you very much in advance.
Regards
Bernhard

I just want to share my solution. In IIS7 if you are utilizing integrated mode, you might get an error that SpellCheckHandler is not registered in web.config.
If IIS is uzing integrated mode then the handlers have to be defined under
If IIS is uzing integrated mode then the handlers have to be defined under
<
system.webServer>
<
handlers>
<
add name="SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI" />

I have wasted over three days trying to get the controls installed and running like they should after an update..
After running into the assembly not found message I started reading all the blogs on this problem - and there are many. I have tried almost everything listed except loading into the GAC which I can not seem to do by copying the dll and I do not have gacutil.
I did a complete uninstall, a restart and a complete install that said it completed successfully. Yet I still get this message on old and even a new screen.
This problem has eaten up tons of time on the part of Telerik users and needs to be fixed by Telerik so that when you do an install or upgrade EVERYTHING that needs to happen to get the controls running happens. Up until this point I was a solid proponent of Telerik but after this, my first attempt to update to a new release, I have some reservations about the commitment on Telerik's part.
Can Telerik say why things that should happen with an install or upgrade are not taking place and what actions they are going to take to address this issue?

Hi,
I have been having a funny problem with one of my pages if I use the RadSessionPageStateCompression adaptor.
My page has a 2 grids and 3 combox boxes the user selects from the combo box and hits apply to get grid data, they can then click a grid row whcih calls a js function passing a value back through the xhttp panel to get data for a detail grid. the population method for the detail grid access the combo boxes as does the needdatasource for the primary grid. everything works as it should for about the first 10 items the user selects from the master grid but on the 11th (not exactly) click the server can no longer see the selected items collection of the combo 'null'.
If i then change to the RadHiddenFieldPageStateCompression adaptor everything works
any suggestions?

situation:
there are two buttons : btnA,btnB
btnB is in RadPanel in RadWindow.
i used radwindow as a container.
btnB is used for edit content.
btnA is used for show Add/Edit form.
flow:
after edit form appeared , and edited some thing ,then i clicked btnB. the data was updated and the RadWindow closed( close the radwindow on server side via RadWindow1.VisibleOnPageLoad = false; )
then i click "btnA" for show Add form again( display radwindow ,because the form is in radwindow ), and i got errors as above.
flow 2:
if i refresh page, then click "btnA" directly ,the radwindow can be shown.
but after edit something ,the radwindow cann't be shown.
please advise.
Thank you

Hi,
I am having this issue with Rad menu that comes with sitefinity. I was able to customize the css but the only issue that I still have is that i don't want this extra space after the text in the child menu items. I tried to change the rmRightArrow for items but didn't work. Please see image attached.
Thank you in advance.
Best Regards,
G
