Question

I am working with a WinForms DataGridView control. I have put this control in a base form and subscribed it to the DoubleClick event. But on the inherited form I want to unsubscribe it from the parent event, and subscribe it to a new event. Is this possible ?

Answer 1

You need to set protected value to DataGridView1.Modifiers property and change the modifier of DoubleClick handler of DataGridView1_DoubleClick as protected.

Base form,

protected void DataGridView1_DoubleClick(object sender, EventArgs e)
{
}

In inherited from’s load handler,

//To unregister handler
DataGridView1.DoubleClick-=new EventHandler(DataGridView1_DoubleClick); 
//Register new handler
DataGridView1.DoubleClick+=new EventHandler(NewDataGridView1_DoubleClick);
