I seem to be having a problem with checkbox events...

I've got in my RadGridView a Column of checkboxes... What i want to do is determine if ANY of these check boxes has been ticked. if one or more have been ticked then it enables a "Next" button, if none are ticked the next button is disabled.

So we need to do this on an event level. However i cannot for the life of me find an event that fires AFTER the checkbox value has been changed! I realise this is not complicated logic, but i cannot find the correct Event handler!

Thanks in advance
Regards
Kevin.

Hi kevin,

You could use the ValueChanged event and check the ActiveEditor.Value property. Please consider the code snippet below:

void radGridView1_ValueChanged(object sender, EventArgs e) 
    GridCheckBoxCellElement checkBoxCell = (GridCheckBoxCellElement)sender; 
    if (checkBoxCell != null
    { 
        bool newValue = (bool)this.radGridView1.ActiveEditor.Value; 
        //... 
    } 

I will be glad to help you if you need further assistance.

Best wishes,
Jack
