Prevent PropertyGrid item from being reset

[Paul]

I want to prevent a user from using the property grid context menu to reset a value that has changed. I tried setting the IsModified property to false, but it is read-only. Is there another way to make sure the "Reset" item in the context menu is always disabled for a specific property grid item?

Hello Paul,

Thank you for writing.

The easiest way to ensure that all elements values in the grid cannot be reset is this:

radPropertyGrid1.RadContextMenu.Items[0].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

If you want to disable the reset for a specific item you need two things:

• Handle the RadContextMenu DropDownOpened event
• Disable the menu reset option for the specific element

Here is the corresponding code for the steps: 

void RadContextMenu_DropDownOpened(object sender, EventArgs e)
{
    if (this.radPropertyGrid1.SelectedGridItem.Name == "BorderColor")
    {
        radPropertyGrid1.RadContextMenu.Items[0].Enabled = false;
    }
}

I hope this helps.

That is what I was looking for. Thanks.
