I want to symbolize nodes (e.g. using IFeatureLayer.Symbology and the FeatureScheme) by representing color of the node with one column from the data table and size of the node by another column in the...

Can anyone confirm if this feature still works in DotSpatial release 1.8 ? In our project the labeling of point feature works just fine, but for linestring features nothing seems to be rendered ?...

Yes this works in release 1.8. Did you label all parts of your LineString or only the largest? Try the largest part to reduce collisions. Have you tried zooming in to a single LineString to check...

I'm not sure how you queried your polygon shapefile. But if you could use FeatureLayers Selection you can simply convert this to FeatureSet by using IFeatureLayer.Selection.ToFeatureSet(). Then you can...

Thanks for the quick response, i tried all the settings you mentioned. A complication may be that the lines (loaded from memory) contain a LOT of vertices following a river, but even after simplifying...

Yes this is possible using a FeatureScheme with unique values.PointScheme myScheme = new PointScheme(); myScheme.EditorSettings.ClassificationType = ClassificationType.UniqueValues; You have to add one...

I updated the plugin. On my machine serialization to a map document now works, Could you please verify?

I can see how that would work for small value sets. I have thousands of features though and want to use color ranges since there would be too many unique values. I was thinking about something like...
View ArticleNew Post: LayerSelected behavior is not what I expect
In DotSpatial.Symbology.Layer, in the IsSelected property, the following code exists: if (base.IsSelected != value) { OnLayerSelected(this, value); base.IsSelected = value; } This appears to call the...

There doesn't appear to be any way to do this short of modifying the source code. In particular, the TableEditorControl in DotSpatial.Symbology.Forms could be trivially modified to add a new...

I am trying to add circle symbols to the vertices of a selected polygon feature in C# but I don't know how to go about it. I would be glad if some one can help me out.

I found the problem as I debugged down into MapLabelLayer.cs, the PlaceLineLabel method expects a basic geometry of type LineString but this particular layer i am feeding it consists of MultiLineString...

OK, finally i found the solution, which is a bit confusing to me ;-) The problem was that we created our LineString features from code like this: featureSet.AddFeature(new Feature(FeatureType.Line,...

I found that using AddFeature with a new feature is never a good idea. I think creating a feature without a featureSet seems to be a bad idea too. That seems to cause more problems than it helps. I...

What for do you need those circles? Maybe you could have a look at the MoveVertex feature of the Editor Plugin.

As long as your code is working for you I don't see a reason to change it. The problems were just something I ran into when I started using DotSpatial and have seen in some discussion posts. At this...
