Text Binding

[MiddleTommy]

I am trying to bind to the Text of a RadCombobox. It works ok but when I change the binding source the combobox says that the value of Text can not be null.
I wish to use the RadComboBox to be a TextBox where the user can type any value and it will be saved into a list of items that is the items source of the RadComboBox for autocompletion of previously entered items. So the Text is separate from the Current SelectedItem.
Any thoughts on how to do this or should I use a different control?

Hi TWT,

We have received similar bug reports from other clients, but we weren't able to reproduce the problem with a simple application. Could you please, open a new support ticket and send us a simple application, that could be used to observe the exception?

Any solutions yet?

I am  trying to do what MiddleTommy is doing too. Say you have a entity and you display it's properties as a list of controls in a dataform. Some of these properties might be of a Type kind. Product.Category for example. When when you add a new product, the product's category has not been set yet which causes the Radcombobox to fail.

Therefore, binding the RadCombobox.TextProperty to a property on the VM that can sometimes return "" or null, causes Radcombobox to fail.

Should it not return to a state where it displays EmptyText?

Hi Werner,

I answered you in the other thread as well. Anyway, we will greatly appreciate a sample project of yours. It will definitely help us in further resolving the problem.
