Have a pretty difficult question for my first post on here. Just to warn you, I am new to Nevron so it may be that the answer to this is actually quite simple. Basically, what I am trying to do is use an NDrawingView interactive map (which I already have) to modify other parts of the page. The problem I am running into is that the eventhandler for mouse clicks on NDrawingView is "OnAsyncClick", which does a callback only on the map. Anything else on the page that gets modified is not posted back and therefor isn't reflected on the screen.

For simplicity's sake, I'm just looking for an example that modifies a label based on the NDrawingView being clicked. The example below will run the code to modify the label, but will not reflect that change. It will only reflect changes to the map (for instance, if I say to change the NDrawingView image based on a click position, it will do that just fine. It just won't change anything that isn't in the NDrawingView control).

NOTE: Had to remove brackets on my asp controls since the forum here seems to use them. Just know that they exist =D

ASP Controls:

asp:Content ID="Content1" ContentPlaceHolderID="MainContentHolder" runat="server"
ndwc:NDrawingView ID="NDrawingView1" runat="server"
Height="350px" AjaxEnabled="True"
AsyncCallbackTimeout="10000" AsyncRequestWaitCursorEnabled="False"
OnQueryAjaxTools="NDrawingView1_QueryAjaxTools"
OnAsyncClick="NDrawingView1_AsyncClick"
AsyncAutoRefreshEnabled="True">
/ndwc:NDrawingView


asp:Label ID="Label1" runat="server" Text="" ForeColor="Red"> /asp:Label



C# codebehind:

protected void NDrawingView1_AsyncClick(object sender, EventArgs e)
{
//Do Some Stuff
Label1.text = "IT WORKED!";
}



Any help would be greatly appreciated!

Hello Christopher,

You can take a look at the following example in the Diagram: http://examplesaspnetdiagram.nevron.com/Frames/NExampleFrame.aspx?ExampleUrl=Examples/DemoDiagrams/NOrgChartUC.ascx

Awesome, that is almost exactly what I needed. One question though: is there a way to do this exact thing using codebehind? Either C# or VB. I'm trying to access the currently selected shape file on a Nevron map in this fashion. Right now they click a shape and that shape is highlighted. I'd also like to pull the name of that ship into a table, text box or something else.

Nvm, found the solution! Thanks for the example!
