In my sample XML the object is "ZB". That "ZB" has two points, "AAD" and "AAG". Both points have coördinates, devided by the "|" character. This is a fixed format, I have to deal with it. Because in our software, we use the data in a dataset. So we convert the XML tot a dataset with the command: Dim myDS As DataSet Dim fsReadXml As New System.IO.FileStream(myXMLFile, System.IO.FileMode.Open) myDS.ReadXml(fsReadXml) After that, I have 4 tables in my dataset: ZB AAE AAG point Automaticly there are relations and hidden id's added. After that, I connect 2 datagrids with this code. One datagrid with all objects and the second grid shows me the coördinates of the selected object in datagrid 1: Dim myBS As New BindingSource myBS.DataSource = myDS DataGridView1.DataSource = myBS DataGridView1.DataMember = "ZB" DataGridView2.DataSource = myBS DataGridView2.DataMember = "ZB.ZB_AAE.AAE_point" So far so good, everything works fine! I can databind labels or other textboxes to the point, after clicking a "ZB" object. Its with this code: TextBox1.DataBindings.Clear() TextBox1.DataBindings.Add(New Binding("text", myBS, "ZB.ZB_AAG.AAG_point.pos")) What do I want? I want the objects and coördinates in one datagrid. So I want to create a view, adding a custom column, and see the results back in a datagrid. I tried the following. All commented lines I tried. I can't find the proper way to build a expression so the coördinates were shown: Dim Test As DataColumn = myDS.Tables("ZB").Columns.Add("test", GetType(String)) Test.Expression = "ZB.ZB_AAE.AAE_point" 'Test.Expression = "Child(ZB.ZB_AAE).point" 'Test.Expression = "Child(ZB_AAE).point" 'Test.Expression = "Child(point)" 'Test.Expression = "Child(pos)" 'Test.Expression = "ZB_AAE.point" 'Test.Expression = "ZB.ZB_AAE.point.pos" 'Test.Expression = "point" 'Test.Expression = "point.pos" 'Test.Expression = "Parent.ZB_AAE.AAE_point.pos" 'Test.Expression = "Parent(ZB_AAE).AAE_point" 'Test.Expression = "Parent.ZB" 'Test.Expression = "ZB_AAE.AAE_point.pos" 'Test.Expression = "Child.ZB_AAE.point.pos" You can use this XML to test: <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?> <!-- File Header --> <DATA xmlns:nl= "http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="file:EN13508.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:gml="http://www.opengis.net/gml"> <ZB> <AAA>AAA</AAA> <AAD>1</AAD> <AAE> <gml:point srsName="Netherlands-RD" srsDimension="2"> <gml:pos>123|456</gml:pos> </gml:point> </AAE> <AAF>2</AAF> <AAG> <gml:point srsName="Netherlands-RD" srsDimension="2"> <gml:pos>234|567</gml:pos> </gml:point> </AAG> </ZB> <ZB> <AAA>AAA</AAA> <AAD>3</AAD> <AAE> <gml:point srsName="Netherlands-RD" srsDimension="2"> <gml:pos>345|678</gml:pos> </gml:point> </AAE> <AAF>4</AAF> <AAG> <gml:point srsName="Netherlands-RD" srsDimension="2"> <gml:pos>456|789</gml:pos> </gml:point> </AAG> </ZB> </DATA>

This threat is very old, but, i have one little question about this. Is it possible to give the .ExpandyClass a name in the propertygrid? Now it displays Applicationname.ExpandyClass. I can't find this property? Giving Categories a name is not a problem, just the expanding item...
