Hi.
I am trying to do the following:
I want to create a ComboBox which can be used like an editable Combobox (i.e. type into the Textfield and select from the auto-complete..) but only entries currently in the combobox shuld be selectable.

The description for the 3rd Combobox on the Combobox/Fist Look Examples page reads somehat like this but typing ist not allowed in that Combobox. (What I expected by setting IsReadOnly, anyhow..)

So - Is it posiible to transform the DropDownCombobox into a keyboard-navigateable-but-non-entiable-Combobox ?

Yours,
Nils

Theming

I have an application that uses Telerik controls, standard WPF controls such as text boxes, and some third party controls from another vendor. I want to give my customers the ability to customize colors, brushes, etc. The problem is that the various toolkits are using different resource keys. If I want to tell the customer how to change the rollover background brush for buttons, I have to tell him about three different resource keys, one for System.Windows.Controls.Button buttons, one telerik buttons, and one for buttons in the other 3rd party toolset. I would rather document one resource key that the user sets in app.xaml and then have some startup code in my app that propagates the setting to the appropriate resource dictionaries for the various tookits.

How do I do that with Telerik controls? Can I just store a value for the telerik resource key in the application resource dictionary? Or do I have to store it somewhere else?

Validation for ComboBox

Hi
I've got a data bound Combox that displays the data from the DB just fine. As the list is a little large, we allow the user to enter in text and auto complete kicks in using telerikSearch:TextSearch.TextPath="..." (as from the sample).

If the user then deletes parts of the text to something that doesn't exist in the list, the resultant entry could be invalid. I've tried various combinations of IsEditable and IsReadOnly being set to true / false but haven't got the desired behaviour.

What I would like to do is either:
1. Wire this combobox up to standard WPF validation. How does this work for this control?
2. Only allow the user to enter text that matches the list and disable them from deleting text to invalidate the entry

Thanks in advance!

RadialGauge Curved Tick Label Text

Hi,

We are working with some large numbers on the Radial Gauge. Some of these numbers are overlapping on our custom gauge unless the font size is set unacceptably low with few labels on the gauge. Also, large numbers (in the 10s of billions range) look rather square in contrast to the curved radial scale.

Is there any way to have tick label text curve around with the radial scale? Do you have any suggestions on the best approach?

Cheers,
Wayne Reid

Toolbox icon still point to old Telerik dlls

Hello,

I recently installed TELERIK 2009Q2 for WPF and every thing went fine.

When I create a new project and add a gridview control using View -> Toolbox,
the control and all the other DLLs point to the library where the older Telerik version was installed (and still exist on my computer).

I did an automatic MSI install and not a manual one.

Your help will be most appreciated.

WPF Examples Demo Project

I have downloaded the trial and demo for the WPF. Could someone tell me how the left navigation bar is built? This is the panel with all the images for each control in the toolkit that you can select.

I open it in VS and HomePage.xaml does not seem to contain it. Examples.xml seems to contain declarations for the items in the list.

I am new to WPF and Telerik so thanks for bearing with me.

Binding to Collection

When I expand the column, to view the child table, I get the error: A TwoWay or OneWayToSource binding cannot work on the read-only property 'AddressFamily' of type 'System.Net.IPEndPoint'.

I had the same error on the parent table - but got around it by explicitly defining the columns and the column bindings as one-way. Not really sure why that was required either, but it worked. But, can't figure out how to do that for the child table. And, I'm not sure if this was the correct approach anyway.

I get this scenario to work correctly with DataSets - but don't want to have to create DataSets for the 50+ objects I need to do this for.

Any thoughts?

The datasource is a collection of custom objects.

XAML is...
