Maybe some of your conditions override the IsReadOnly
condition. This is possible when your conditions are not set to AutoUnapply
or you are using animations intensively. I am not sure which condition causes this problem. Please open a support ticket and share your theme with us. We will be glad to help you fix it.
I have attached a sample theme based on our Vista theme, which modifies cell color to Red when the cell is read only. Please note that simply setting the ReadOnly
property of GridViewColumn
does not update the visual state of the grid. You need also to call RadGridView.GridElement.Update(false)
