#30 Columns Down, Rows Across (Transpose View)

[Petar Tasev]

First of all, I want to say this control is absolutely amazing, thanks for you hard work!

Is there any way to make the columns display on the left side of the control, so that they are much like rows, and the rows are displayed across as if they were columns. This would essentaily be a transpose of the data in the objectlistview.

I have attached an image where I had to use a row in a DataGridView control as the column names, before loading the data as another column. Each file opened would create a new column with its data.

Would love if you can provide this feature, or at least tell me how I can go about doing it myself.

Thank you!

It's possible, but difficult.

I did try this a while ago, and there were a couple of blockers in my code that made it problematic. From memory, some properties (like renderer and cell editors) are currently decided by OLVColumn, and without some serious refactoring cannot be calculate per cell. But this sort of pivoting requires those properties to be calculate by cell and NOT by column.

I'd still like the columns to decide the renderer and cell editors, just that they should now be drawn as row headers, rather than the typical column headers. Is there no way to simply draw the columns on the side?

No, there is no way to "simply" draw columns on the side. "You know not
what you ask" :)

Underlying ObjectListView is a normal MS-written ListView control. It has
some very strong assumptions about how it will work, and it is very
difficult to work against those fundamental assumptions.

With some clever coding, you can get around some of those assumptions (and
I think this is one that could be circumvented), but many are just
unchangeable.

Regards,
Phillip
