display a form at selected mouse coordinates

Objective: (This is not an MDI application) Display a child form containing a datagridview that contains the child records of the selected row in a datagridview. Have this display on a parent form right below the selected row in the datagridview.

Problem: I am unable to get the correct location of the cursor on the parent datagridview control passed to the child form so the child form displays correctly.

I am passing the location to the constructor of the child form so that I can call this child form as you would call ContextMenu.Show(DataGridView, e.X, e.Y) but I am not sure how the Point gets set to the Control and not the parent form. When I use e.X and e.Y. I am successful in displaying the child form related to the parent form coordinates but not the control

Any help would be greatly appreciated.

Thanks
Tim

    I made a couple of additional changes and it works fine now. I created an overloaded show method with the x and y coordinates of the mouse and now it works fine. Thanks Mamta.

    Hi Mamta,
    I thought of that last night as well but when I tried it this morning I still don't get the desired results.
    Here is the snipits I am using for testing.

    MAIN FORM:
    private void dgvPreAuditData_MouseUp(object sender, MouseEventArgs e)
    {
    LaunchChildGrid(e.X, e.Y);
    }

    private void LaunchChildGrid(int xPoint, int yPoint)
    {
    ChildGrid myChild = new ChildGrid(dgvPreAuditData, xPoint, yPoint);
    myChild.ShowDialog(this);

    }

    CHILD FORM:

    public ChildGrid(Control parent, int xPosition, int yPosition)
    {
    _xPosition = xPosition;
    _yPosition = yPosition;
    _parent = parent;
    InitializeComponent();
    PositionMe();
    }

    private void PositionMe()
    {
    Point ParentPoint = new System.Drawing.Point(_xPosition, _yPosition);
    this.Location = ParentPoint;
    }

    Hi,

    Have you changed the StartPosition property of the child form to 'Manual' This is essential to make it appear at selected position on the parent form. Let me know if the problem persists even after you have done this.
