[Solved] Up/Down arrow keys don't work as expected

[Chris Ward]

When there is a multiline textbox in the RowDetails of a RadGridView and the up or down arrow key is pressed, while at the top or bottom of the textbox respectively, the RadGridView selection moves to the previous / next row.  Is this supposed to happen, and how can I prevent it from happening?

Edit: As a note, this appears to be happening with all unhandled events.  I understand the functionality of passing unhandled events up the tree, but I'd like to know how to prevent that from happening in certain cases.

Hello Chris Ward,

  This behavior is controlled by the TextBox itself since it decides whether some keyboard events are handled or not. For example, in the case where you use Down Arrow key in the middle of a text the grid will not execute its move/select logic since the keyboard events will be handled by the TextBox. Contrary, when you press Down Arrow key at the end of a text the grid will executed its keyboard handlers since the TextBox will not handle any events. 

In case you would like to have a TextBox that does not allow any navigation you will have to create a custom TextBox control that handles all KeyDown events. 

All the best,
