I have a GridGroupingControl where the datasource is bound to a table in a dataset. If I change the datasource to another table, the grid still displays the previous table''s columns and they are all empty! How do I change the datasource to another table such that the grid shows the data from the new table correctly? TIA

Try this code: gridGroupingControl1.DataSource = null gridGroupingControl1.DataMember = null gridGroupingControl1.ResetTableDescriptor() gridGroupingControl1.DataSource = newDataTable gridGroupingControl1.TableDescriptor.SetItemProperties(gridGroupingControl1.Engine.GetSouceList()) gridGroupingControl1.Table.TableDirty = True gridGroupingControl1.Table.SummariesDirty = True gridGroupingControl1..Refresh()

With the latest version ( and later), the only call that should be necessary is ResetTableDescriptor().

Clay, I tried the exact same code that you posted. It didn''t work. When I bind the datasource for the very first time,every thing is okay. The next time nested table is empty and the thrid time the top level table is empty. Syncfusion

You should probably upgrade. In 3.0, we ship a sample, \Syncfusion\Essential Suite\\Windows\Grid.Windows\Samples\Grouping\GridGroupingRebind, that shows rebinding working. When using nested tables, you also should call this.gridGroupingControl1.TableDescriptor.Relations.Reset();

gridGroupingControl1.TableDescriptor.Relations.Reset(); I don''t see that method. I tried to gridGroupingControl1.TableDescriptor.Relations.RemoveAt(0) and this didn''t work either. Is there anyway to make it work in I would like to use upgrade to 3.0 as last option. Thanks shankar

Try gridGroupingControl1.TableDescriptor.Relations.Clear() . It will be later tomorrow before I have access to 2051.

Clay, gridGroupingControl1.TableDescriptor.Relations.Clear() did not work either. I got runtime error argument out of range. childtabledescriptor. m_childTableDescriptor = gridRequests.TableDescriptor.Relations(0).ChildTableDescriptor This line appears after i relations.clear and bind the datasource. Any help would be greatly appreciated

The only way I would know to get this reliably donne in is to dispose and recreate the gridgroupingcontrol. http://www.syncfusion.com/Support/user/uploads/ResetData2051_e6ae9f92.zip If you update to the current release, you could avoid this.
