Question

I have a DataGridView that’s bound to a DataSet. It has columns DateCreated, Weight, DateUsed. Those three columns do not take up much horizontal space on DataGridView that is nearly full screen. Is it possible to have those columns wrap back to the top if the view is wide enough to support a second group of those colums. So across the header it would read DateCreated, Weight, DateUsed, DateCreated, Weight, DateUsed. Then when a row is clicked, only 3 cells would be highlighted, not all six. Is there something that can provide this functionality?

Answer 1

I don’t know of anything like that out of the box.

You could create that effect yourself. You would need to decouple the actual data from the presentation of the data. Instead of a single DataRow per grid row, you’ll need to merge them together to show multiple rows on a single row.

So your helper method might do the following:

• Compare the width of the DataGridView to the number of rows
• Determine how many DataRows columns would be visible
• Build a new DataTable with extra column sets to represent each column
  • Example: DateCreated1, Weight1, DateUsed1, DateCreated2, Weight2, DateUsed2, etc.
• Populate the DataTable with the original DataSet
• Bind the DataGridView to the new table

Some considerations: can users sort the data? If so, you’ll have to write that yourself.

Do you need to be able to add new rows using this view? That sounds very difficult with this kind of view.
