controls question

[szabelin]

Hi Marina, I have tried DataGrid. I need to
hide/expand/show subrows, so I thought I had more control
drawing the Table myself.

Do you have any suggestions for my questions?

Thanks!

You want dynamic controls? then you have to live with this. I have to do
the same
I don't like it but that's the way it is for now
The framework can be smarter and recreate the previously created dynamic
controls on postback or something
It does not today and you have to do it yourself
Good luck and I hope you find a better solution and share it with us

I am talking about the DataList, not the DataGrid.

The DataList, as part of its template, might need another DataList, to
render the subrows.

You could write custom javascript to do this if necessary.

You might want to consider looking into a 3rd party grid that supports
hierarchical data.
