Hi, 

I'm struggling for something that perhaps is very easy...

I have assigned a DataTable as Datasource for my GridView.

The data is correcly shown and the boolean values are mapped on checkboxes.

I save back the values to the database getting the new values from the DataTable.

However sometimes the user open the form, click on checkboxed value, and then click on the Save button.

It seems that if you don't deselect the modified Row, the new value of the checkbox is not stored into the DataTable, so I save the old value, while in the GridView you see the new value.

Is there a way to force the sync right after the click on the checkbox?

I've tried with something like this, but without success.

private void RadGridView1OnCellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
            e.ActiveEditor.EndEdit();
            e.ActiveEditor.Validate();
}

Great, the best way to find a solution is to write on the forum: in two minutes I found what I've been looking for hours.

I was forgetting to set:

GridViewCheckBoxColumn.EditMode = EditMode.OnValueChange

to the column. Now it works.
