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.ClearSelection();
        MyDataGridView.Rows[hti.RowIndex].Selected = true;
    }
}

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

For completness of this question, better to use a Grid event rather than mouse.

First Set your datagrid properties:

SelectionMode to FullRowSelect and RowTemplate / ContextMenuStrip to a context menu.

Create the CellMouseDown event:-

private void myDatagridView_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        int rowSelected = e.RowIndex;
        if (e.RowIndex != -1)
        {
            this.myDatagridView.ClearSelection();
            this.myDatagridView.Rows[rowSelected].Selected = true;
        }
        // you now have the selected row with the context menu showing for the user to delete etc.
    }
}

private void dgvOferty_CellContextMenuStripNeeded(object sender, DataGridViewCellContextMenuStripNeededEventArgs e)
    {
        dgvOferty.ClearSelection();
        int rowSelected = e.RowIndex;
        if (e.RowIndex != -1)
        {
            this.dgvOferty.Rows[rowSelected].Selected = true;
        }
        e.ContextMenuStrip = cmstrip;
    }

TADA :D. The easiest way period. For custom cells just modify a little.
