Dynamic Layer question..

JoshV — Tue, 27 Jul 2010 13:24:31 GMT

I have a dynamic layer and I know I can't put Maptips on it but I would like to do something similar so a user could see some attributes when they click a feature or better yet, hover over it. I took some code from the samples and have shown it below but it gives me a "BAD_PARSER_VALUE" error at the OutFields line. I'm not sure this is the sample I need based on what I'm asking for above. Can someone reply and let me know what I need to change? The first layer in my mapservice is an SDE point featureclass that I want to show at least 2 attributes on mouse hover.

Thanks,

<TextBlock Text="{Binding [API]}" FontWeight="Bold" />
<StackPanel Orientation="Horizontal">
<TextBlock Text="Web site: " />
<TextBlock Text="{Binding [Operator]}" />
</StackPanel>

These Binding causes the BAD_PARSER_VALUE. I think you meant to put {Binding Attributes[API]} and {Binding Attributes[Operator]}.

Both on the same line where TextBlock=? Can you show me what you mean based on my code? Thanks

I suggested replacing your binding statements with those on separate lines, since each target a different property. Using your code then, I just replaced those two lines.

Also, you mentioned in your title and question that you are working with DynamicLayer. I do not see that in your code. You are using ArcGISTiledMapServiceLayer.

If you intend to use a dynamic layer instead, you will need to set MapTip in code-behind after the dynamic layer has initialized.

Do you get this error in Design or in run-time?

I know this kind of error can happen during the design but it should work at run-time.
