Hi,
I'm writing a winform app (as practice) that has as one of its features a button that reads an xml file to a datagridview.
No matter what I do I get two columns instead of one.
The "first column", I retrieve and place the text "Holy Cat" in its header text. This column contains no data from the xml file.
The second column contains the correct data from the xml file.
When clicked the "first column" is not shown as a column by the event delegate; but the "second column" reports that it is column 1.
Can anybody spot the bug in my code?
TIA
Regards
Mark
