    I just updated my code and the refrenced dlls to use the Q2 2010 release of telerik controls.

    I have a functionality incorporated which calculates values on a cell basis referring to other cells within the grid.
    I am using the cellvaluechanged-event to submit the current position and the entered value to my calculation routine.

    If grid.Rows(e.RowIndex).Cells(5).Value = "Adjusted Net Requirement (User Input)" Or grid.Rows(e.RowIndex).Cells(5).Value = "Supply Adj. Forecast (User Input)" Then
                If IsNumeric(e.Value) Then
                    _supplyLogicLayer.calculateOnTheFly(dsSupply, grid, e.RowIndex, e.ColumnIndex, e.Value)
                    '_supplyLogicLayer.calculateOnTheFly(grid, e.RowIndex, e.ColumnIndex, e.Value)
                End If
            End If

    the caluclateonthefly procedure basically grabs values from specific cells and does the calculation with them.

    Since I upgraded to the new release this procedure takes a tremendous amount of time - the Q1 release has been much faster in processing it that way. Addionaly after setting a new value to a certain cell (f.e. dr.Cells(ColumnIndex).Value = 1000) it isn't shown in the grid directly. I need to refresh it or expand and collapse a child to see the new value.

    It is probably important to know that I am using a childgridrelation within the grid.

    Let me know what you think.


    P.S.: We could do a netviewer remote session that you guys can see what is happening here.

    Here is in an update on this.

    I tried to get closer on the root cause of this issue and figured out that the grid only slows down when using an hierarchical grid.

    Once I remove the hierachy relation from the grid it performance absolutly fast. Plugging the relation back in it slows down ultimativly.

    Here is my code for setting up the realtion. I do not think that there is anything wrong with it, right?

    grid.DataSource = dsSupply.Tables("SUMMARYFINAL")
    Dim tpl As GridViewTemplate = New GridViewTemplate
    tpl.DataSource = dsSupply.Tables("DETAILFINAL")
    Dim rel As GridViewRelation = New GridViewRelation(grid.MasterTemplate, tpl)
    rel.RelationName = "Summary2Detail"
    rel.ParentColumnNames.Add("MFG Strategy")
    rel.ChildColumnNames.Add("MFG Strategy")

    I really appreciate your help and thoughts on it as this is an urgent issue on my end and I do not know how to proceed right now.
