DataGridView and DataSets

[Illegal Operation]

I have a dataset that contains a query stateing the following: select * from table where id = @id. This query works fine. The problem I am having is that I have 2 Windows forms, Form1 contains a datagrid and Form2 contains the textboxes, comboboxes etc. How can I double click on a record in the datagrid and then that record should populate form2? I know it should be handled in the datagrid_doubleclick method but How can I let Form2 know that I have double clicked on id 1?

you'll setting dataSet public,when form2 load and for form2 data

Can you possibly give me an example of what you are saying?

use MouseDoubleClick instead...

Point p = dataGridView1.PointToClient(new Point(e.X, e.Y));
DataGridView.HitTestInfo tmp_hinfo = dataGridView1.HitTest(p.X, p.Y);
if (tmp_hinfo.RowIndex == -1 || tmp_hinfo.ColumnIndex == -1)
return;
// Now you have row index and column index

what you can do is provide an overload constructor for the second form that takes a datarow as a parameter public Form2(DataRow drow):this() { //fill the data by indexing through all the values this.text1.text=drow["Name"].ToString(); } and as to figuring out which data that has been selected just handle "CellDoubleClick" and/or "RowHeaderMouseDoubleClick" events and then send the datarow selected by using the selected row from the event handler argument. like in this code: private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e) { new Form2(dataGridView1.Rows[e.RowIndex].DataBoundItem).Show(); } hope this does the trick for you
