Expandable columns in DataGridView

Hi,

I have to create a customized datagridview to enable the expandable columns. If anyone already worked out this, please help me on this.

Thanks in advance,

Natraj

What do you mean by expandable columns ones that the user can resize if that is what you are looking for. in the designer add a DataGridView to you form and AllowUserToResizeColumns is true by default.

Be aware that a DataGridView does not show relations unlike the DataGrid control...

If you decide to use a DGV you could play with the Visible property of the DGVColumns... which results in a hide/show effect...

Thanks for your reply !

Expandable column in the sense drilling down the columns....

One column can hide multiple columns. The user can see the child columns by clicking the + button before the column name

Something like this..

Stage 1 : (Before clicking the + button )

Products + Categories Release Date

Product1 ... 11/07/2006

Stage 2 : After clicking the + button

Products - Categories Release Date

Category 1 Category 2 Category 3

Product1 1 2 3 11/07/2006

Note : Bold letters are column names..Unbold letters are values

Ouput should be something like this.

Thanks,

Natraj.

Guys, you can use a dataset designer (includen in VS) and create the xml squema for your dataset's tables, in there, you can define datarelations between the tables which will therefore make your datagrid show the expandable + signs when you bind that dataset to it.
