I need to know is there is a way to zoom in and zoom out with using the built in control. What I need to be able to do is set a button to zoom in and a button to zoom out. When that button is clicked it automatically zooms in a certain amount and visa versa. Is this possible? I do not want the user to have to click on a button then click the document to zoom. Then click back on the pointer button.
Thanks in advance
Chris

Check the following article: Enchancing Interactivity with Client-Side ScriptingIn short you can use following JavaScript code to zoom in and zoom out 1.5 times: Code:
var bitmapViewer1=document.getElementById("<%=BitmapViewer1.ClientID%>");
bitmapViewer1.setZoom(bitmapViewer1.getZoom()*1.5);
Code:
var bitmapViewer1=document.getElementById("<%=BitmapViewer1.ClientID%>");
bitmapViewer1.setZoom(bitmapViewer1.getZoom()*0.66);
