What have you tried so far, this could be a fairly simple process.

i have created the datagridview in one form and textboxes in another form. and i wrote code for add one value from DGV to textbox. but my problem is i don't know how to get more than one value to the same textbox from the DGV column..

That should have been the easiest part?

string myval="";
myval+=dataGridViewRow.Cells["SomeColumn"].Value.ToString();
myval+=dataGridViewRow.Cells["SomeOtherColumn"].Value.ToString();
//now send string over to textbox
