C# - DatagridView and ContextMenu
I have a datagridview where I show infomation about products. I want to bind a contextmenu when the user selects a cell and then right clicks on that cell. I have another contextmenu and that one is bound to the columns of the datagridview. If a user right clicks on a column the contextmenu shows.
I have tried like this but it does not work. The context开发者_如何学JAVA menu shows when the user right clicks on a cell, but the contextmenu that is bound to the column header does not work.
private void GridView1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
productContextMenu.Show(GridView1, e.Location);
}
}
How do I make it so that when the user right clicks on a datagridview shows up?
Many thanx in advance.
EDIT
Thnx for the answers. I solved the problem like this:
private void GridView1_MouseUp(object sender, MouseEventArgs e)
{
DataGridView.HitTestInfo hitTestInfo;
if (e.Button == MouseButtons.Right)
{
hitTestInfo = GridView1.HitTest(e.X, e.Y);
if (hitTestInfo.Type == DataGridViewHitTestType.Cell)
{
productContextMenu.Show(GridView1, e.Location);
}
}
}
Both the contextmenus shows. When I click on the column that context menu shows, and when I click on a cell that contextmenu shows.
Try this
private void dataGridView1_CellMouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
contextMenu.Show(datagridview, e.Location);
}
}
or
private void dataGridView_MouseUp(object sender, MouseEventArgs e)
{
// Load context menu on right mouse click
DataGridView.HitTestInfo hitTestInfo;
if (e.Button == MouseButtons.Right)
{
hitTestInfo = dataGridView.HitTest(e.X, e.Y);
// If column is first column
if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 0)
contextMenuForColumn1.Show(dataGridView, new Point(e.X, e.Y));
// If column is second column
if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 1)
contextMenuForColumn2.Show(dataGridView, new Point(e.X, e.Y));
}
}
For the problem with the relative position, you can also use this aproach:
DataGridViewColumn dgvC = new DataGridViewColumn();
DataGridViewRow dgvR = new DataGridViewRow();
dgvC = dgv.Columns[e.ColumnIndex];
dgvR = dgv.Rows[e.RowIndex];
Point p = new Point();
p.X = (dgvC.Width * e.ColumnIndex) + e.X;
p.Y = (dgvR.Height * e.RowIndex) + e.Y;
dgv.ContextMenu.Show(dgv, p);
