C# – How to Disable Double Click on the Header of a DataGridView

cdatagridviewwinforms

I want to do some stuff while double click on a Gridview (Row) not single cell. Means on a double click event handler not on MouseDoubleClick event. But i am not able to disable the header column and row double click event..and also want to load data to combobox(ComboBox is on the same form) when i double click on the GridView Row. Help me Please..!!!

private void gvLoadAllData_DoubleClick(object sender, EventArgs e)
{
    if()
    {
        //Do Something
    }
}

I already had CellDoubleClick event defined and doing stuff, my issue was that a double click on the header was firing that event and therefore crashing the app.

Taking Disaster's idea, I just added the following to get around that event.

if (e.RowIndex == -1) 
    return;

The simplest way is an anonymous method passed into Label.Invoke:

// Running on the worker thread
string newText = "abc";
form.Label.Invoke((MethodInvoker)delegate {
    // Running on the UI thread
    form.Label.Text = newText;
});
// Back on the worker thread

Notice that Invoke blocks execution until it completes--this is synchronous code. The question doesn't ask about asynchronous code, but there is lots of content on Stack Overflow about writing asynchronous code when you want to learn about it.

You should check the RowIndex and ColumnIndex property of the event arguments. If one of them is negative, it means that either a row header or a column header is clicked, you should ignore that event.
