Hi,

How can I tell on the double click event of the datagrid whether or not a
row was double clicked or a column header was double clicked?

My problem is I open a new form on the double click event of the datagrid
based on the selected row. Users however are used to doubleclicking the
column headers to have them automatically resize the column width to see all
of its contents. Unfortunately when they double click the columns headers,
the event is still fired which opens up the form for the selected row.

So, basically if the double click is on the column header and not a row, I
don't want to open my form...but I don't know how to tell if it is the
column header that is double clicked.

Thanks!
 
John,

I would capture the mouse up and mouse down events as well. Every time
the mouse down event or mouse up event occurs, store the coordinates
somewhere. Then, when the double click event fires, pass those coordinates
to the HitTest info. Then, you will know if you are on a row, or a column
or row header.

Granted, there is a slight margin of error here if the user is moving
their mouse erratically while double clicking, but it should work for almost
all cases.

Hope this helps.
 
Thanks alot. Good idea. I'll give it a shot.
