Need DataGrid Help

[gggram2000]

I have a form with a comboBox and a datagrid. When I select an ID from the comboBox it will display a particular item with that ID on the datagrid. I would like know how I can create a new row everytime I select an ID from the comboBox. For example, right now when I select an ID it just replaces the row I already have instead of creating a new one...I know it has to be somewhere in the line of:

 if (this.comboBox1.SelectedIndexChanged = true)
then Create New Row...

Can anyone help me? I'd really appreciate the help, maybe someone has tried this already.

Assign a DataTable as your DataSource for the DataGrid.
Then when you select an item in the combobox, add a new row to that datatable. It will then appear in the DataGrid.

For solving this problem you can use binding list.
ComboBox_SelectedIndexChanged event use this binding list with data grid binder to bind the data at runtime to the datagrid. This will add the new row in the data grid, without disturbing the previous rows. But do not clear the binding list.

Hey, thanks for the input. What I did instead was create a table with an invoice number that i generate and add 1 in a function. What i do is save the invoice number on the table with all the data and then at the end display all the data for that particular Invoice number on the datagrid. It isn't very simple but it works great since i don't display anything on the datagrid until the different items have been saved in the database then just simply display all the data with that number.

The code for adding a row to a datagrid at runtime:

datagridName.rows.add(new object[] {ColumnValue1, ColumnValue2, ... });

this will add a single row to the datagrid at the bottom of all the rows
