Hi,
when i add labels for MapPolygonLayer, the labels is not showed. please help me check.

private void SetLayerLabel(IFeatureLayer layerObj, string strExpression)
{
        var sbLable = new StringBuilder();
        sbLable.Append("[");
        sbLable.Append(strExpression);
        sbLable.Append("]");
        layerObj.ShowLabels = true;
        LabelSymbolizer labelObj =  new LabelSymbolizer()
            {
                FontFamily = "Arial",
                FontSize = 12,
                FontStyle = FontStyle.Regular,
                Orientation = ContentAlignment.MiddleCenter,
                PartsLabelingMethod = PartLabelingMethod.LabelAllParts
            };
            layerObj.AddLabels(sbLable.ToString(), "", labelObj, "Label");
            layerObj.LabelLayer.Symbolizer.PreventCollisions = true;
}

thanks.

Hi,
I want to add a feature set to specified point in map layers.I used this code to add it 
IFeatureSet iFeatureSet = FeatureSet.Open(Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), @"OfflineLayers\Soils.shp"));
                    
IMapLayer lay1 =(IMapLayer) iFeatureSet;
                     map.Layers.Insert(2, lay1);
                     IMapFeatureLayer lay = map.Layers[2];
But I can not cast 'DotSpatial.Data.PolygonShapefile' to type 'DotSpatial.Controls.IMapLayer' is there any way to fix this problem?
Thank you

Hi CodePlex1987,

Unicode font is not a problem any more with Dotspatial Version 1.6 and 1.7.

To pass my problem, I add an additional file with same name as Shp file with extention = *.cgp. I use Unicode font (UTF-8). Therefore, In the content of the file, I enter UTF-8.

For example, my shp file is Dancu.shp; I create a new file with name: Dancu.cpg. In the content of the file, I enter UTF-8. (see the image below)

Hope this helpful.

Created Unassigned: Export Feature and FeatureLayerActions [25949]

Hi,
I am translating DotSpatial.Symbology.Forms and I made changes in the FeatureLayerActions.cs and the SymbologyFormsMessageStrings.resx

Here my changes to localize the message box output

```
public void ExportData(IFeatureLayer e)
{
using (var frmExport = new ExportFeature())
{
frmExport.Filename = e.DataSet.Filename;
if (ShowDialog(frmExport) != DialogResult.OK) return;

// Create a FeatureSet of features that the client wants exported
FeatureSet fs = null;
switch (frmExport.FeaturesIndex)
{
case 0:
fs = (FeatureSet) e.DataSet;
break;
case 1:
fs = e.Selection.ToFeatureSet();
break;
case 2:
var features = e.DataSet.Select(e.MapFrame.ViewExtents);
fs = new FeatureSet(features) {Projection = e.Projection};
break;
}

if (fs.Features.Count == 0)
{
fs.CopyTableSchema(e.DataSet);
fs.FeatureType = e.DataSet.FeatureType;
}

fs.SaveAs(frmExport.Filename, true);

if (MessageBox.Show(Owner, SymbologyFormsMessageStrings.ExportFeature_Features_Load,
SymbologyFormsMessageStrings.ExportFeature_Features_Exported,
MessageBoxButtons.YesNo) == DialogResult.Yes)
{
LoadFeatureSetAsLayer(e, fs, Path.GetFileNameWithoutExtension(frmExport.Filename));
}
}
}
```
And this 2 strings in the .resx file

ExportFeature_Features_Exported The layer was exported.
ExportFeature_Features_Load Do you want to load the shapefile?

I have a Problem if I need to use a Code page file .cpg thogether with my .shp file.
In this case the .cpg file is not exported too and the data in the exported file are shown with wrong coding.

Any idea how to change the Code to Export the cpg file too?

Hi dear gis4sd agian!
Thanks for answering to me!
I am working with Geoserver 2.6, PostgreSQL 9.2, PostGIS2.1.2 and my Shapefile are in Farsi language.
I already convert my Shpfile to UTF-8 Unicode and my spatial databases are built in same Unicode, also my Geoserver is adjusted to Unicode UTF-8.
But when I download a WFS from Geoserver as a zip file it don't have a ".CPG" file! Just a ".CST" file by ISO-8859-1 Unicode.
And then when I opened this shapefile in ArcCatalog and etc my data are illegible!
I changed this ".CST" to UTF-8 and after created a ".CPG" file with UTF-8 Unicode but nothing is changed!
I attached pictures!
Thanks again!

Hi friend,

sorry for my misunderstood.
As I understand now, your source file has no problem with font. The problem happen after you upload the file on to WebGIS and download it back.

In my opinion, strings of the downloaded file is destroyed and we can not correct it. You should find solusion in Geoserver services.

Best regard.
