I am vs 2010 user and vb developer. I have seen Telerik Rad Controls and how they perform and can only say that this is an amazing developer's tool! My problem though, is the fact that I already have 90% of my vb application in vs2010 designed using winform controls and was wondering whether there was an easy way to convert the already existing controls and forms to telerik?

Thanks,
Fawzieh

Hello Fawzieh,

Thank you for writing.

The only tool that might help you convert standard WinForms application to RadControls for WinForms is the VSX package that comes with our suite. Please refer to the following help article, which describes how to take advantage of this functionality.

I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.

I would like to firstly thank you for your prompt reply which sets the bar very high for other forums!
I tried your suggest solution but am getting the following error message:
"Error executing custom action
Telerik.wincontrols.vsx.actions.UpdateReferencesAction:Object
reference not set to an instance of an object"

My other question is how can I programitically add a column to a RAD MultiColumnComboBox.?

Thank you again,
Fawzieh

Hi Fawzieh,

Thank you for writing.

Could you please try and update your VSExtensions for Win Forms (in the latest version there are fixes for the upgrade and convert options) and try again to convert your existing project to Telerik enabled one. Here are the steps to do that:
1. Go to the Extension Manager (Tools -> Extension Manager) in VS2010.
2. Uninstall Telerik WinForms VSExtensions.
3. Go to the Online Gallery section in the Extension Manager and search for Telerik WinForms VSExtensions. Download and install them and restart the VS2010.
4. Try again to convert the project (If this don't help could you please open a support ticket and send us your *.vbproj and *.sln files in order to try and identify the problem).

In regards to your question about RadMultiColumnComboBox, please note that internally its consists of RadGridView inside of a drop down. You can access the RadGridView instance via the EditorControl property. Here is an example of how to add a column to the underlying grid:

Hi, I have a visual studio 2013 application that has windows controls and windows forms, how do I convert all those controls (button, checkboxes , menubars, etc) into telerik controls?

I tried the wizard and it doesnt do anything, am i missing something?

Hi Jim,

We do not offer a tool that converts standard controls to our alternatives. What we do offer is a configuration wizard, which can add our assemblies to your project. More information is available here: Creation and configuration wizard. 

List with the controls and the assemblies they reside is available at the very end here: http://www.telerik.com/help/winforms/installation-deployment-and-distribution-redestributing-telerik-radcontrols-for-windows.html.

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
