DataGridView with CheckBox cell problem

Question

I have a DataGridView with a DataGridViewCheckBoxColumn column, which is databound to a list. The problem is that the databound boolean property for this checkbox is updated not when the check box is checked/unchecked, but after the CellLeave event in other words after the cell looses focus. I want this property to be updated right after the check/uncheck. There's an event CurrentCellDirtyStateChanged which is fired right after check/uncheck happens, so I can use it to update the propery manually. Is there a better way to do this?

Answer 1

You can listen for the CurrentCellDirtyStateChanged event and force Commit the change:

void dataGridView1_CurrentCellDirtyStateChanged(object sender,
    EventArgs e)
{
    if (dataGridView1.IsCurrentCellDirty)
    {
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}

take a look at Binding.UpdateSourceTrigger Property
