ReadOnly GridViewCheckBoxColumn

[Mel Grubb]

I have a check box column in a RadGridView, and I can't seem to make it read only.  I've searched through the forums, and only found people with the opposite problem.  I've seen posts about people with read only grids where they want one column editable.  What I want is a checkbox column that is NOT editable, but try as I might, you can edit the check boxes in this grid.

I set the grid's ReadOnly property to True.
I set the individual column's ReadOnly property to True.
I set the grid's AllowEditRow to False.
I even set the grid's BeginEditMode property to BeginEditProgrammatically.

Nothing has any effect.  What do I have to do to make a simple read-only grid?

I am having the same problem. If I set everything to readonly (like you mention) the CellBeginEdit event isn't fired, but you can still change the state of the checkbox by clicking on it.

Please help!

Hi Mel Grubb,

I confirm that this is an issue. We are aware of it and it will be addressed in our upcoming service pack. You can set the Enabled property to false when handling the CellFormatting event:

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridCheckBoxCellElement)
    {
        RadCheckBoxEditorElement checkboxElement = e.CellElement.Children[0] as RadCheckBoxEditorElement;
        checkboxElement.UseDefaultDisabledPaint = false;
        checkboxElement.Enabled = false;
    }
}

Remove the UseDefaultDisabledPaint line and the checkbox will appear as disabled.

If you need further assistance, please write us back.

Best wishes,

This has solved my problem - thanks. I look forward to a bug fix however. When is SP1 due out?

Hi Ben,

Currently we collect issues to address in the service pack. It will be released in 2-3 weeks from now. There is an internal build that addresses the checkbox issue. Please open a support ticket and I will send it to you. I am looking forward to your reply.

The work around is ok for now - I would rather stick to major releases as it means I don't have to update my repositories and release builds.

[Mel Grubb]

I will stick with the workaround as well for the moment.

I'm having the same problem as described above but I'm using version 2010.2.10.806 of the Telerik.WinControls assembly.

The grid has AllowEditRow set to true and BeginEditMode has been set to BeginEditProgrammaticaly.
The grid has a GridViewCheckBoxColumn and the ReadOnly property has been set to true.

With this configuration i can still change the checkbox even without calling grid.BeginEdit().

I've used the workaround as described in the thread and that does work but in my opinion changing the checkbox should only be possible after the BeginEdit method has been called.
With the workaround i have to build the logic that when in EditMode the checkbox may be changed and otherwise not.

Any advice or do i have to set some specific properties for the checkbox?

Kind regards.
