right-click event handling

sachi vasishta

In a form I dropped a datagridview and a contextmenustrip. When I run the form it displays some info from the db to the dgv. The contextmenustrip has a item called open which opens a new form and also carries some variables to that form. My question is when I right click on a particular row then that row's 1st,2nd,and 3rd cell values should be copied to 3 string vars and are passed to the new form

Accepted answer

Sachi,I think you want to send values without left click on that row,but by directly right click on row and select open and send values.am i correct?.

This can be done in two steps add code in cell mouse down event
like

String s1,s2,s3;

 private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)

            if(e.Button==MouseButtons.Right)

                 s1 = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();

                 s2 = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();

                 s3 = dataGridView1.Rows[e.RowIndex].Cells[2].Value.ToString();

        }


then in open menu item event

send those values s1,s2,s3 to another form.

Sachi ,I also did not think about this ,till you question me.I thought context menu is designed for whole dgv.we cant use it for single row. after that i think about Mouse down event& mouse right button.Now it works well. Sachi ,after post a question try to select accept answer if you got answer & satisfied.Have a nice week end.

no vimal it is not correctly working. I mean I have to first left-click to select a particular row then if I right-click on that row then that row's cell values are copied and passed.When I ran the program and right-clicked on row three the first-row's cell values are passed to new form. What I want is when I debug the prog and when I right click on a particular row then that row's cell values are to be passed.(by default it is selecting the first row so if I right-click on any other row then that row's cell values are not being passed)

Sachi,
in open menu add code like below

private void openToolStripMenuItem_Click(object sender, EventArgs e)

           String s1=dataGridView1.CurrentRow.Cells[0].Value.ToString();
           String s2=dataGridView1.CurrentRow.Cells[1].Value.ToString();
           String s3=dataGridView1.CurrentRow.Cells[2].Value.ToString();
           //add code to pass these s1,s2,s3 to another form via overloaded constructor.and show that form
