I need to implement the parent child relation into the single datagirdview row.
This row contains the "+" sign if it contains the child data, when user will click on this "+" sign it will expand the another child grid from that selected datagridview row.

I am using vs 2008.

Thanks in advance.

Hi Ashlesh Patel,

The new DataGridView control doesn't support this. You may need to use the Old DataGrid control. You canfind the code in the FAQ here.
If you have any doubts, please feel free to let me know.

Hi Bruce,

Your post is very helpful to me to understand the grid.
But my issues is to open the child grid into the parent gird row. This parent grid row (if contains the child data then and only then) display with the "+" sign.

Any help will be appreciable.

You can add a DataGridView to the Control collection of the parent DataGridView, and show or hide it when you click "+" sign. Also need to adjust the location of the childDataGridView according to the row in the parent DataGridView.

Hi Bruce,

I have already tried it with your suggestion, but I think vs2008 is only providing textbox column, combobox column, link column, image column and button column for the gridview's particular control container collection.

Hi Ashlesh Patel,

Maybe I'm not clear enough. I didn't mean that we need to add the DataGridView as a column to the column collection of the DataGridView. But just add the DataGridView to the control collection of the DataGridView. Like the following:

this.dataGridView1.controls.add(this.dataGridView2);
