Combobox with duplicate display member values.

Currently using a RadComboBox which is databound from a linq query.

The ValueMember is a unique ID and DisplayMember is a user entered field.

If the user enters duplicate values for the "name" field, both will display in the combo box, however SelectedValue will always return the first matching name in the list - even if the underlying ID's are different.

Is this by design or is it a bug?

Problem with tab key

Hi,

Normally when we press the tab key we can change the focus to the next control of the form in the order of the tabIndex property.

I have a RadForm with some controls inside but I don't know what I've done but the tab key does'nt work anymore. It just produces a sound "ding" but the focus does'nt change. It worked, but I cannot found the property wich could fix my problem.

Any Idea?

Thank you

Node label text disappears

Hi

I'm using version Q3 2007 SP1. I have a ContextMenuStrip linked to a RadTreeView. If I right-click on a node and select the "Rename" menu option, I call the BeginEdit() method of that node. If I then change the label text (but before pressing enter) and I right-click on the RadTreeView again to bring up the ContextMenuStrip, the text within the label disappears.

Any ideas?

Export to Excel

Q1 2008 SP1
Visual Studio 2008
I am unable to find "RadGridViewExcelExporter". There is no RadGridViewExcelExporter under "Telerik.WinControls.Data." I've got "Telerik.WinControls.Data." and "Telerik.WinControls.UI.", but no "Telerik.Data."

In C:\Program Files\Telerik\RadControls for WinForms Q1 2008 SP1\bin
there is a TelerikData.dll.

What am I missing?

Also, how far backward compatible with Microsoft Office/Excel is this feature?
All the way back to Office 97?

Html-like and symbols ">" or "<"

Hi everyone,

I face a problem in my project, I have a GridView with Html rendering. I use HTML-like tags in my cells. But the data between the tags is written by users. Sometimes, users wrote in the data symbols like ">" (greater than) and "<" (less than). When they do so, the data behind those symbols and the symbol itself are not displayed. Is there any workaround to display the all comment of the user in that case ?

Thanks,

[Nean]

I'm using the ExportToExcelML.Runexport with version 2009 Q2.

Thx

Selected index changing

Hi,

On our current project we are facing the same problem as nightcoder on stackoverflow: http://stackoverflow.com/questions/782313/how-can-i-handle-combobox-selected-index-changing

We would like to know if there is any way of retrieving the previously selected item of a RadComboBox, or if it is possible to subscribe to an event that contains this information.

Best Regards,
Diederik.

Combobox on mouse over, multiple rows getting highlighted

Hi there,

I am using RAD Combobox in my windows application. I am facing a small problem. Whenever i move the mouse over the combobox items, multiple rows are getting highlighted. Please let me know if there is any property which can restrict this functionality. I want that particular row to be highlighted upon mouse over and not multiple rows.

FYI: I have attached a screenshot which shows multiple rows highlighted.

Regards,
Prasad
