How do i do this in gridgrouping ccontrol

Hi Shankar,

Try this code snippet to add the grouped columns in a grouping grid. Here is a code snippet.

this.gridGroupingControl1.ShowGroupDropArea = true;

GridTableDescriptor gdr = this.gridGroupingControl1.GetTableDescriptor("Table1");
gdr.GroupedColumns.Add("ColumnA",ListSortDirection.Ascending);

Let me know if this helps.
Best Regards,

It didn''t work. runtime error. gdr is null

DataSet newDs = new DataSet();
newDs.ReadXml("c:\\Shankar\\Group1.xml");
this.gridAttributes.ShowGroupDropArea = true;

gridAttributes.DataSource = newDs.Tables[0];

GridTableDescriptor gdr = this.gridAttributes.GetTableDescriptor("Table1");
gdr.GroupedColumns.Add("Columna", ListSortDirection.Ascending);

Hi Shankar,

The reason is that you are misspelled the table name. In general, GetTableDescriptor method takes the table name as the argument. can you please double check your DataTable name?. Let me know if i am missing something.

Try this code:

GridTableDescriptor gdr = this.gridGroupingControl1.GetTableDescriptor(ds.Tables[0].TableName );

///Or

this.gridGroupingControl1.TableDescriptor.GroupedColumns.Add("ColumnA",ListSortDirection.Ascending);
