Resize of data area after grouping

[Tim Cousins]

Unbound RadGridView with Datatable passed as data source

Columns programatically set (Best fit, Custom headers etc), grid height Auto sizes depending on number of rows passed in Datatable (built-in functionality - not set programatically).

Grid populates and operates exactly as expected, however after "grouping" by a particular column, the "data rows" element of the grid is not redrawn leading to a scroll-bar.

I'm pulling my hair out trying to resize the data area in the "GroupByChanging" event to show all rows (with Group headers) without the need for a scroll bar - your help would be greatly appreciated !!!

Apologies for what is probably a straight forward solution and my thanks in advance,

Tim.

Finally cracked it.  This may not be the best/neatest solution, or indeed work in all cases, however it may be of some benefit to others.

Private Sub RadGridView1_GroupByChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCollectionChangedEventArgs) Handles RadGridView1.GroupByChanged
'Resize the grid according to whether the group by clause is set
Dim _gvi As UI.GridViewInfo = e.GridViewTemplate.Owner.MasterGridViewInfo
If e.GridViewTemplate.GroupBy <> "" Then
    e.GridViewTemplate.Owner.Height = _gvi.GridViewElement.ChildRowHeight + _gvi.TableHeaderRow.GetActualHeight(RadGridView1.GridElement)
Else
e.GridViewTemplate.Owner.Height = (_gvi.GridViewElement.DesiredSize.Height * _gvi.Rows.Length) + _gvi.TableHeaderRow.GetActualHeight(RadGridView1.GridElement)
End If
End Sub

Great components though, well done Telerik team !
