Toolbar and zooming

[martyphee]

When I click on zoom it shows a dropdown with 100%-400%.  How do I get it to allow me to select a region?

 I've tried this in both IE and FF.

When generating an image this is the only supported way of zooming.

For more interactivity you have to select .NET as the Rendering Format.

I have it selected, but it's not doing it.  I'm running the app through VS is that makes a different.  Even running it from out dev environment I get the same results. 

<chartfx7:Chart ID="CumTransVolume"   EnableViewState="true"   RenderFormat=".NET"   runat="server"   Width="800px"   Height="600px"   AllSeries-Gallery="lines"   Visible="false">   </chartfx7:Chart>

I figured it out I think.  At least in my test page it's working.

 I'm setting the chart through code and calling CumTransVolume.Reset();

 Once I reset the Renderformat it worked.

chart.Reset();

 Does reset every property, including RenderFormat to the default values ("image" in this case).

I was going through the postings and the zooming feature seemed like a nice touch.  However, I hit a snag.  It seems that my series links no longer work nor my drop down menus.  The menus are displayed, but no postback occurs.

1) Try with a simple form. One in which you drop the chart and that's it.

2) If this works and yours doesn't then please provide us with details of what you are doing in your form. A recent post:

Explains how adding the chart to the control tree at the wrong time can cause this problem. If you are creating your chart dynamically (as opposed to at design-time) this may be the problem you are experiencing.
