DataGridView Hide/Unhide Columns

Question

If I have a column with lets say 10 columns.

Out of the 10, 5 are visible by default.

Is there a simple way of making some type of context menu to allow a user to select out of the 10 columns which one's are visible and which one's aren't?

It shouldn't be too difficult to do that. Try something like this: private void Form1_Load(object sender EventArgs e) { ContextMenuStrip strip = new ContextMenuStrip(); strip.Items.Add(-- Visible if checked --); for (int i = 0; i { ToolStripMenuItem tsmi = new ToolStripMenuItem(); tsmi.Tag = i; tsmi.Text = dataGridView1.Columns[i].HeaderText; tsmi.Checked = true; // add code to set this to false if not visible by default tsmi.Click += toolStripMenuItem_Click; strip.Items.Add(tsmi); } dataGridView1.ContextMenuStrip = strip; } // add this handler manually rather than via designer private void toolStripMenuItem_Click(object sender EventArgs e) { ToolStripMenuItem tsmi = (ToolStripMenuItem)sender; tsmi.Checked = !tsmi.Checked; int colNumber = (int)tsmi.Tag; DataGridViewColumn col = dataGridView1.Columns[colNumber]; col.Visible = !col.Visible; }
