Hi,
I'm trying to slow down the rotator, however Ive found this in the demo:
FrameDuration - specifies the time in milliseconds each frame will display in automatic scrolling scenarios. This property is ignored in the Buttons and SlideShowButtons modes.
In this case, how do I change the speed, or can't I?

Hello,
we are trying to set up programmatically a tooltip manager on a RadGrid defined programmatically in a class inheriting Control. We associate both the RadGrid and the RadTooltipManager with the RadAjaxManager, and the generic item of the RadGrid is associated with a RadContextMenu with RightClick. The ContextMenu works, but we can't access programmatically to the OnAjaxUpdate event of the ToolTipManager (and we can't define the tooltipmanager on a ascx control, due to architectural design) because the compiler response is that the OnAjaxUpdate in not accessibile:
Error 7 'Telerik.Web.UI.RadToolTipManager.OnAjaxUpdate(Telerik.Web.UI.ToolTipUpdateEventArgs)' is inaccessible due to its protection level)
Could anyone help us?
Thanks a lot for the attention.

Hi, All:
I have 18 columns in my RadGrid. One of the column is an <asp:CheckBox and another column is with an <asp:TextBox.
I would like to have validation: whenever the checkbox is checked, that textbox must have something inputed.
Please help.
If you suggest me to use GridChectBoxColumn instead of <asp:CheckBox, I can surely follow.
thanks.

Hi,
My tooltip displays my control, which contains radtextbox, checkbox and a radcombobox.
All are fine except the radcombobox is hidden behind the tooltip control when fired ?
Any ideas please ?
Thanks

Hello,
I can not find any solutions for the next problem.
In my datagrid i have a column with values like 001, 002, 003, etc..
The values must stay like they are, string values. (all the other data in the column is also string.)
When i export to excel the values become 1, 2, 3, etc..
My question is, how can i managed to let the values stay strings, when i export to excel.

My web part works as expected, but if I add a radTextbox after the tree instead of a standard web textbox control, AJAX no longer works, instead generating an "... Invalid Viewstate error"

I have a scenario in which a user may select from a number of predefined queries which loads a RadGrid. The grid is generated dynamically as the columns may vary from query to query. This is all working until I tried adding DetailTables for the MasterTableView. I tried to recreate my issue by following examples in documentation and it all worked, until I added a button that would simulate the selection of a query. If the grid is added to the control collection initially without any DetailTables it seems like it is impossible to add one later. Is this by design?
Here is the code for my sample application.
Any thoughts or advice would be very appreciated.
Thanks,
Adam

Hi all,
I'm evaluating the suite and I have a problem with the window component.
When I create 2 or more windows, when a move a window, the contents of ALL the other windows desappear and when I stop to move the window, all the contents re-appear.
It's normal?
I don't want this behaviour...
Many thanks.
Giorgio.
