NT 7.0

How can I show a context menu in the chart [for example when a user double clicks in the chart]:

 

Code

MenuItem [] menuManualButton = new MenuItem [] { new MenuItem( "Text 1", eventHandler1), new MenuItem( "Text 2", eventHandler2), }; ContextMenu contextManualButton = new ContextMenu( menuManualButton ); contextManualButton.Show( (ChartControl) sender, Cursor.Position );

My question is what I have to provide in the show function as the first parameter? This should be a control object.

This works like a charm and the context menu is shown exactly on the mouse position where the double click occurred:

 

Code

//--------------------------------------------------------------------------------------- private void ChartPanel_MouseDoubleClick( object sender , MouseEventArgs eventArguments ) //--------------------------------------------------------------------------------------- { MenuItem [] contextMenuItems = new MenuItem [] { new MenuItem( "Menu 1", eventMenu1 ), new MenuItem( "Menu 2", eventMenu2 ), }; ContextMenu contextMenuObject = new ContextMenu( contextMenuItems ); contextMenuObject.Show( (Control) sender, eventArguments.Location, LeftRightAlignment.Right ); }

Don't forget to add the handler to the chart:

 

Code

ChartControl.ChartPanel.MouseDoubleClick += ChartPanel_MouseDoubleClick;

and unload it with:

 

Code

ChartControl.ChartPanel.MouseDoubleClick -= ChartPanel_MouseDoubleClick;

Unfortunately, so far have not been able to compile in NT8.

Problem with this line:

 

Code

private void ChartPanel_MouseDoubleClick( object sender ,MouseEventArgs eventArguments )

MouseEventArgs is an ambiguous reference between System.Windows.Input.MouseEventArgs and System.Windows.Forms.MouseEventArgs.

Unfortunately, so far have not been able to compile in NT8. Problem with this line:   Code private void ChartPanel_MouseDoubleClick( object sender ,MouseEventArgs eventArguments ) MouseEventArgs is an ambiguous reference between System.Windows.Input.MouseEventArgs and System.Windows.Forms.MouseEventArgs.

Under NT8 these areas are a mixture of WPF and Forms so you have to specify whichever one you want to use in full:

 

Code

// we're in WPF space private void ChartPanel_MouseDoubleClick( object sender , System.Windows.Input.MouseEventArgs eventArguments ) { } // we're in Forms space private void ChartPanel_MouseDoubleClick( object sender , System.Windows.Forms.MouseEventArgs eventArguments ) { }

@ratfink, that's a step in the right direction, but there still seems to be a long way to go to get it to work in NT8.

Thanks for your help, will continue to play around with this.

In NT8 you can also add items to the right-click context menu when you've selected an indicator on the chart, which avoids having to mess around with the mouse controls.

The idea is to not use the NT8 context menu but to have my own.

I do NOT want to reload the chart after the user inputs are made to my menu.
