even if I know that there is a special forum for the GGC I want to ask my question in this forum because I think that it´s a general question.
I use the Filterbar feature in a GGC and need to serialize the filtered data in XML with the WriteXML method of the datatable object in the following way.
Try Dim xw As New XmlTextWriter("c:\temp\apoInventarListe.xml", System.Text.Encoding.UTF8) xw.Formatting = Formatting.Indented Dim dt As DataTable = Me.grdgrpXLImport.DataSource dt.WriteXml(xw, XmlWriteMode.WriteSchema) xw.Close() Catch ex As Exception MessageBox.Show(ex.Message) End Try
But as a result of this code I always get the complete datatable and not only the filtered rows from the GGC.
Can anyone help me to serialize only the filtered rows of a datatable.

Hi Karsten,
Please refer the forum thread for Serialize grouping table descriptor. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=41724
You can Save the GridEngine changes to xml using the Engine.WriteXml method and intialize GridEngine from Xml using CreateFromXml method. Here is a code snippet.
// intialize GridEngine from Xml System.IO.FileStream file = new FileStream("XML11.xml",FileMode.Open); System.Xml.XmlTextReader xr = new System.Xml.XmlTextReader(file); GridEngine engine = GridEngine.CreateFromXml(xr); this.gridGroupingControl1.Engine.InitializeFrom(engine); xr.Close();
//GridEngine changes to xml System.IO.FileStream file = new FileStream("XML11.xml",FileMode.OpenOrCreate); System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(file,System.Text.Encoding.UTF8 ); this.gridGroupingControl1.Engine.WriteXml( writer); writer.Close();
Best regards, Haneef

Hi Haneef,
thank you for your answer but unfortunately your suggestion is not the solution in my case.
With your suggested code and the link I can serialize the schema of the grid but not the data itself.
For example: I have a GGC with about 50 items in the datasource of the grid. Now I filter with the filterbar method and as a result there are at least only 10 items in the grid.
My problem is now that -with my code- I ALWAYS get 50 items in my XML file regardless of the filter settings.
What I want to do is just getting the filtered resultset in my serialized XML file and not all of the data from my underlying datatable.
It would be really helpful for me if you can help me.
Thank you in advance Regards, Karsten

Hi,
in the meantime I have found that the visible (=filtered) records are in the FilteredRecords collection (Me.GridGrouping.Table.FilteredRecords). But actually I´m having the problem that I can´t get this collection in a DataTable object.
Can anyone help me with this?
Regards, Karsten
