Adding line to datagridveiw from textbox

Question

hi there your all ok i hope. Gat stuck been trying to add lines to my datagridview from various textboxes. just like you add an item to a shoping basket but every time i click my button i only replace what i had already entered with what is in my textboxes. any help below is the code i am using } DataTable dt = new DataTable(); dt.Columns.Add = (DAYtypeof(string)); DataRow DR = dt.NewRow(); DR[Day] = textbox1.Text.Tostring(); dt.Rows.Add(DR); dataGridView1.Datasource=dt; } thanks

Sure the code will become: DataTable dt = (DataTable)dataGridView1.Datasource; if (!dt.Columns.Contains(Day)) { dt.Columns.Add(Daytypeof(string)); // only add if not already created } DataRow DR = dt.NewRow(); DR[Day] = textBox1.Text.Tostring(); dt.Rows.Add(DR); dataGridView1.Datasource = dt; It may rebind automatically without the need for the last line - comment it out and see.

If you want to add lines to the DataGridView when you will need to add rows to the existing DataTable and rebind. What you're doing at the moment is creating a new DataTable and then binding to that so it will replace all the lines you previously had with the new ones.
