Right click to select a row in a Datagridview and show a menu to delete it

I have few columns in my DataGridView, and there is data in my rows. I saw few solutions in here, but I can not combine them!

Simply a way to right-click on a row, it will select the whole row and show a menu with an option to delete the row and when the option selected it will delete the row.

I made few attempts but none is working and it looks messy. What should I do?

I finally solved it:

  • In Visual Studio, create a ContextMenuStrip with an item called "DeleteRow"

  • Then at the DataGridView link the ContextMenuStrip

Using the code below helped me getting it work.

this.MyDataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MyDataGridView_MouseDown);
this.DeleteRow.Click += new System.EventHandler(this.DeleteRow_Click);

Here is the cool part

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
    if(e.Button == MouseButtons.Right)
        var hti = MyDataGridView.HitTest(e.X, e.Y);
        MyDataGridView.Rows[hti.RowIndex].Selected = true;

private void DeleteRow_Click(object sender, EventArgs e)
    Int32 rowToDelete = MyDataGridView.Rows.GetFirstRow(DataGridViewElementStates.Selected);

I hope the code will help others :-)

I welcome any correction if there is an error.
