[Solved] Paging, Drag and Drop for grouping is not working for radgrid having default groupByexpression on Date in IE browser

[Sunil]

we have a telerik radgrid in a usercontrol created programatically with default group by expression added programatically.
Issue we are facing is grid feature like paging, sorting, drag and drop on grouping panel doesnot work only on IE browser if default groupbyexpression added is for date field. Date field is stored in database as Datetime and we are retrieving as it is from database and formatting the column using radgrid's gridDatetimeColumn DataFormatString = "{0:MM/dd/yyyy}". 
Below is the code snipped used 


    For Each dc As DataColumn In RadGridList.DataSource.Columns
                Dim objcolentity As New BoundColsEntity()
                objcolentity = LstBoundColsEntity(LstColCount(dc.ColumnName))
                If objcolentity.visiblity = True Then
                    Select Case objcolentity.ColumnFilterType
                        Case "DateSelction"
                            Dim datecolumn As New GridDateTimeColumn
                            datecolumn.DataField = dc.ColumnName
                            datecolumn.UniqueName = dc.ColumnName
                            datecolumn.HeaderText = objlistCmnFncs.OrgtermReplace(objcolentity.columnDisplayName.ToString)
                            datecolumn.FilterControlWidth = Unit.Pixel(120)
                            datecolumn.ItemStyle.Height = Unit.Pixel(40)
                            datecolumn.HeaderStyle.Width = Unit.Pixel(170)
                            datecolumn.Visible = True
                            datecolumn.SortExpression = dc.ColumnName
                            datecolumn.PickerType = GridDateTimeColumnPickerType.DatePicker
                            datecolumn.EnableTimeIndependentFiltering = True
                            datecolumn.DataFormatString = "{0:MM/dd/yyyy}"
                            datecolumn.FilterListOptions = GridFilterListOptions.VaryByDataType
                            datecolumn.Groupable = enableGrouping
                            RadGridList.MasterTableView.Columns.Add(datecolumn)
                        Case "DBvalues"
                            Dim ComboFilterColumn As New DBFilter(dc.ColumnName, RadGridList.DataSource)

Hello Sunil,

We will need all of the grid definition to be able to replicate the issue locally. Please open a support ticket to send us a very basic runnable sample web site so we can reproduce the issue and debug the application accordingly. This will enable us to determine the cause of the problem and to provide an accurate solution.

Regards,
