Deep,

Thanks for your post.

Which version are you using now? Could you send me your sample application to recreate this problem, which would be very helpful for us to fix this problem.

Thanks.

Deep,

It seems the exception is not caused by our MapSuite Wpf component, becuase from your stack trace of exception, I can not find any method of MapSuite. Or you might provide the wrong stack trace or stack trace is not entire one just part of them.

Hope you could provide more information to us that can help us solve your problem.

Thanks
James

Hai Yale and James,

Thanks for your reply, the code is working good, but when i convert it into user control it arises some exception, as u said i here attached the two samples, one is normal one which working good without user control

normal sample with out usercontrol.

cid-08ec3041618e8ee4.skydrive.live.com/self.aspx/.SharedFavorites/Normal%20sample.rar

the problem one is user control one. plz take a look into this. i jus migrated the normal sample to usercontorl one. after that it throws exception in map layer and finding the feature layer. U can see the output and workable model in normal sample, so i attached that too ain above link.

Hi yale,

plz check this sample

Deep,

I can recreate your problem, I compare two samples and I found the reason that you get the exception.

In the second sample, you put MapSuite Wpf control to the MapUserControl, and add MapUserControl to the main Window, I think it's fine. The problem is that you create another member variable MapUserControl in UserControl1, it's the same as you create a new WpfMap and call Refresh(). I am afraid it's not working if you choose this way, the right way is that drag the WpfMap control to a container and after InitializeComponent then the Refresh method that can work.

The correct way is using the MapUserControl which is already in main Window, I name it mapUserControl, and call mapUserControl.getFileandLoad("Default"); I have modied a little with your second sample and add another button to make it works.

Please let me know If you have more questions.

Thanks
James

Yes james. its working,you placed the new button in the main window, but i want that button("Use This one") to be placed inside the usercontrol.
map Viewer is one user control, map file selector is another user control, am using this two user control in one main form, if we select any file in selector control that should be viewable in map viewer control, is it possible to place that button inside the user control, coz i have tried lot and hanging with diff diff exceptions. so can u see how it will be possible???

ThinkGeo · March 22, 2016, 8:39am

Deep.

There are many ways to match your requirements, I have an idea that you can define a static delegate and then you can access the private method in another UserControl. Please look at my updated code for detail.

Thanks

Hai

This is first time am using your component, i not yet read the documentation of this map suite also,coz am in rush to do this. i searched many components and finally choose yours and directly started my development, so i thought some layer concepts of your suite throwng error., so i pinged u, but it seems my mistake,

Thanks James
