How to replace zooming with Custom Zooming in ToolBar

[hasanma]

I've a function to perform Custom Zooming In & Out.

How can I hook up this in the Zoom button(command) in the toolbar?

You can override any command functionality by capturing the InternalCommand event.

I'm using the folloing code to create a command & then the handler. By doing this I get a new Tool bar button.

That not exactly what I want to do. I want my "Zoom Off" command to replace the ChartFX "Zoom" toolBar command.

How can I do that. Also, I couldn't fire InternalCommand event as you suggested. 

chart2.Commands.AddCommand(4);

chart2.Commands[4].Enabled = true;chart2.Commands[4].Text = "Zoom Off";

chart2.ToolBarObj[15] = 4;  // I'm just using 15 because I don't know what to use

chart2.UserCommand +=

new CommandUIEventHandler(chart2_UserCommand);

The InternalCommand event is there with all the other events. I don't know why you don't see it.

You can also replace the Zoom button in the toolbar with any command, either pre-defined or custom. In the default toolbar, the Zoom button is index 18 (separators count as items too).

Note: Because of the location of this posting I am assuming you are using Chart FX for VS 2005 Windows Form control.

Is there any way to get the value of Zoom tolbar button using code

rather than hardcoding the value to 18.

Yes. You can loop through the Items and find the one that has CommandId.Zoom as the command Id.
