Right click to select row in DataGridView

Right click to select row in DataGridView

To allow users to select a row in a DataGridView by right-clicking on it, you can handle the CellMouseDown event of the DataGridView control and set the Selected property of the clicked row to true. Here's an example:

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e) { if (e.Button == MouseButtons.Right) { dataGridView1.ClearSelection(); dataGridView1.Rows[e.RowIndex].Selected = true; } }

In this example, we handle the CellMouseDown event of the DataGridView control. We check whether the right mouse button was clicked (e.Button == MouseButtons.Right). If it was, we clear the current selection (dataGridView1.ClearSelection()) and set the Selected property of the clicked row to true (dataGridView1.Rows[e.RowIndex].Selected = true).

By handling the CellMouseDown event in this way, you can allow users to select a row in a DataGridView by right-clicking on it. Note that if you also want to display a context menu when the user right-clicks on a row, you can use the same event handler and show a context menu using the ContextMenuStrip class.
