Context Menu strip - Top left

[gborges]

Hi all!

I am in trouble trying to positioning a context menu strip.

I will explain my application, here.

There is a usercontrol, which the user can right click using mouse and so, I would like that a customized menu appers, just after this action.

I create a context menu, using this code:

            private void InitializeContextMenu() {
            this.components             = new System.ComponentModel.Container();
            this.ticksMenuStrip         = new System.Windows.Forms.ContextMenuStrip(this.components);
            this.ticksToolStripMenuItem = new System.Windows.Forms.ToolStripMenuItem();
            this.tenthMenuItem          = new System.Windows.Forms.ToolStripMenuItem();
            this.seventhMenuItem        = new System.Windows.Forms.ToolStripMenuItem();
            this.ticksMenuStrip.SuspendLayout();
            this.SuspendLayout();
           
            // 
            // ticksMenuStrip
            // 
            this.ticksMenuStrip.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
            this.ticksToolStripMenuItem});
            this.ticksMenuStrip.Name = "ticksMenuStrip";
            this.ticksMenuStrip.Size = new System.Drawing.Size(153, 48);
            // 
            // ticksToolStripMenuItem
            // 
            this.ticksToolStripMenuItem.DropDownItems.AddRange(new System.Windows.Forms.ToolStripItem[] {
            this.tenthMenuItem,
            this.seventhMenuItem});
            this.ticksToolStripMenuItem.Name = "ticksToolStripMenuItem";
            this.ticksToolStripMenuItem.Size = new System.Drawing.Size(152, 22);
            this.ticksToolStripMenuItem.Text = "Ticks";
            // 
            // tenthMenuItem
            // 
            this.tenthMenuItem.Name = "tenthMenuItem";
            this.tenthMenuItem.Size = new System.Drawing.Size(152, 22);
            this.tenthMenuItem.Text = "1/10 of scale";
            this.tenthMenuItem.Click += new System.EventHandler(this.tenthMenuItem_Click);
            // 
            // seventhMenuItem
            // 
            this.seventhMenuItem.Name = "seventhMenuItem";
            this.seventhMenuItem.Size = new System.Drawing.Size(152, 22);
            this.seventhMenuItem.Text = "1/7 of scale";
            this.seventhMenuItem.Click += new System.EventHandler(this.seventhMenuItem_Click);
            //
            //
            //
            this.ticksMenuStrip.ResumeLayout(false);
            this.ResumeLayout(false);

        }

I get the mouse right click using this code:

        protected override void controlEx_MouseDown(Object sender, MouseEventArgs e) {

            switch (e.Button) {
                case MouseButtons.Right:
                    this.ticksMenuStrip.Show();
                    break;
            }
            return;
        }

The problem is that when I right-click over the user control the context menu appears on top left position of the screen, but I would like that it appears just where I click using the mouse.

I read that I would add a notifyIcon in order to do it, but it also does no works.

Could someone help me?

Thank you in advance!

The Show method of a context menu is overloaded and optionally takes a point as an argument. Set this to the mouse coordinates.

 
protected override void OnMouseDown(MouseEventArgs e) 
{
           base.OnMouseDown(e);
           if (e.button ==  MouseButtons.Right)
           {
                    this.ticksMenuStrip.Show(e.Location);
           }
}

This "looks" better because the ContextMenuStrip displays where the persons mouse event was captured, NOT the location of a control, which in some cases, could be very large. Example: Form1.

Your statement of:

"but I would like that it appears just where I click using the mouse." means that this is your best choice.

protected override void controlEx_MouseDown(Object sender, MouseEventArgs e) {

            switch (e.Button) {
                case MouseButtons.Right:
                    this.ticksMenuStrip.Show(Control.MousePosition);
                    break;
            }
            return;
        }

This is the line vs what you had of: this.ticksMenuStrip.Show();

protected override void controlEx_MouseDown(Object sender, MouseEventArgs e) {

            switch (e.Button) {
                case MouseButtons.Right:
                    this.ticksMenuStrip.Show();
                    break;
            }
            return;
        }
