Thanks Randy! that solved the issue

Hi Randy, I appreciate your timely response. The solution you have posted just about perfectly solves my problem. The code you have posted allows me to do my way of handling the chart once user selects the area to zoom in. That's great! But there is one major issue I have run into now. Firefox is not rendering the chart as .NET client control. I completely understand that firefox does not support ActiveX control and that is what is causing the issue. But is there any other way to handle this. We dont want to lose our firefox users (who constitute about 50% of our users) and we dont want to force them to use IE instead. I want the charts to be interactive in both the browsers. We also have Mac users and am currently not sure what issues we'll run into there. Please let me know if you have any resolution for firefox. Thanks Much! Maz.

Hi, I have already posted couple of queries on this. Can somebody please help me resolve this issue ASAP. I have the zooming functionality enabled on my chart. I have also disabled scrolling on the chart. I dont want any scrolling on the chart. Now, when the user drags the mouse and selects an area on the chart to zoom in - I would like to capture the range (new x and y co-ordinates) being displayed on the screen. I dont mind capturing the event either before or after the zoom actually occurs. I just want the new set of x1,y1,x2,y2 co-ordinates (range) plotted on the zoomed in chart. I have tried capturing the x co-ordinates using chx.AxisX.Labels.Item(0) , chx.AxisX.Labels.Item(1), chx.AxisX.GetScrollView etc and likewise someother properties but none returned the zoomed-In co-ordinates. Thanks, Maz.

Hi Frank, Thanks for your response. The events are working fine if the renderformat is anything other than .NET. My purpose: I would like to capture the new (zoomed in) X and Y (x1,y1,x2,y2) co-ordinates when the user zooms into the chart. By capturing the co-ordinates I can display a custom datagrid with additional information about the data points present in that selected co-ordinates. For the zoom to work - selecting a quadrant by dragging the mouse with left click, the render format has to be .NET. I want to capture the events server side. As I said the events are generating fine if the renderformat is image, i guess the issue is not with granting full trust or not. I think the reason why the event is not getting triggered server side is because the .NET client control is more like an ActiveX control. But if I am not able to capture the UserZooming event then I think it defies the purpose of having it in the first place. Can you Please post a sample that can serve my purpose. Is there a way I can capture the UserZooming event in javascript and do an ajax call to the server? Thanks, Maz.

The method you are talking about works fine. The problem here is what if you want to do some work when the user zooms into the chart. I am talking about UserZoom and UserZooming events that are not triggered when renderformat=.NET If we have a client conrol (html - javascript) button that triggers a call back, it would not carry along the event arguments for the event (userzooming) that needs to be accessed. When the user zooms into a particular quadrant I would like to know how we can access the X and Y coordinates being viewed by the user at runtime. Hope I was clear.

Hi, Events on the chart like 'UserCommand', 'UserZoom' and 'UserZooming' are not trigerred if the RENDERFORMAT=".NET"... I use the feature Renderformat=".net" so that the zoom functionality works (zooming into the quadrants of the chart unlike having zoom percentages ranging from 100 to 400). Can somebody please help me avoid this trade-off. How can I trigger the zoom events with renderformat=".NET"? Thanks, Mazhar.
