Hello, recently we began to encounter exceptions using Telerik GridView. Exception message:

System.NullReferenceException: Object reference not set to an instance of an object.
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at Telerik.WinControls.Keyboard.ChordMessageFilter.CreateInstance()
   at Telerik.WinControls.Keyboard.Shortcuts.AddShortcutsSupport()
   at Telerik.WinControls.Keyboard.Shortcuts..ctor(Control owner)
   at Telerik.WinControls.RadControl.EndInit()
   at Telerik.WinControls.UI.RadGridView.EndInit()
   at CreditAdmin.CardAdmin.Controls.Notifications.InitializeComponent() in c:\_Projects\CreditAdminTeboil\EmsAdmin\CreditAdmin\CardAdmin\Controls\Notifications.Designer.cs:line 149
   at CreditAdmin.CardAdmin.Controls.Notifications..ctor() in c:\_Projects\CreditAdminTeboil\EmsAdmin\CreditAdmin\CardAdmin\Controls\Notifications.cs:line 17...

It seems like this happens only when we use ALT shortcuts (to navigate trough tabs ant some other functions). Does anyone knows what could be the cause of this problem ?

Hello Simonas,

Thank you for contacting us.

Before getting to your question, we would like to check something related to your license. Your account shows no purchases and it seems that you have not downloaded the WinForms suite from our site. Since it is our policy to support users in good account standing, I would kindly ask you to give us more details on the license you are using:

- In case you have downloaded it from another site/account, please let us know so that we can update your account and provide you with proper support services; 

- In case you have obtained a copy of our controls through the company you work for, please ask the purchase holder to add you as a License Developer to the purchase. This will give you full access to the products your company has purchased, to our downloads section, and to our support ticketing system. Additionally, all your questions will be reviewed according to the license you have. More information on License Developers you can find here: http://www.telerik.com/faq

I have moved your forum post to our support ticketing system (which is private communication channel) to avoid sharing confidential information in the public Forums. You can find the ticket in Your Telerik Account.

As to the question at hand, I am not sure how exactly to reproduce this exception. The grid does not have any functionality that includes Alt shortcuts (event if you are using tabbed views). This is why I want to kindly ask you to provide us with the exact steps for the issue reproducing. Perhaps it would be better if you can assemble a small sample project that shows the issue.
 
Thank you in advance for your patience and cooperation.

Regards,
Dimitar
