DataGrid rows question

[bigfoot]

I'm using M$ DataGrid and this is a Windows desktop application.
I have some records (1000 or so) that I have sorted into categories, and I want the DataGrid to be able to collapse and expand the rows to show only the records of one type or another.

I added buttons to the DG, for collapsing the rows, but I can't get to the rows property to set them to 0.

And I'm not sure that's the way to go anyhow.

If anyone can please get me close on this, please let me know.

I only know the basics of the M$ Datagrid, but from what you are saying would ideally suit a Treeview and Grid together. The Tree would contain the summary, and clicking on the nodes would then display the contents of that node in the grid. It also helps to minimise how much data you ever need to display in the grid.


Sweep
...if it works dont mess with it

Thanks Sweep, but I thought of that too.
They want something like Outlook has with the plus and minus buttons.
I can use a 3rd party control, but I'd rather stay away from them and build it inhouse so I don't have to dist. another dll.

I wanted it to look something like this, but I don't want a grid within a grid because then every sub category will have it's own horz. scroll bar.

Is no good for what I am looking for.

This is the look I am after:

Why don't you use a Master-Detail Dataview ?

 

[bigfoot]

Because what I have seen of master-detail, when you open the sub records, they look like individual grids and we want to have one grid.

Thanks for the replies. Please keep them coming.

Has no one done this?

I haven't looked at the code for this but from the description it looks as though you may be able to make a few modifications so that each "group" has an expand/collapse button:

The datagrid is a Windows application and not an asp.net.

But thanks anyway.

Apologies...I keep forgetting which forum I'm in!

Don't know if I get your comment right, but Master-Detail is also possible in one single datagrid.

The master records will have a plus sign in fornt.
