Hello,

           I am using Telerik version 2013.3.1127.40. The Problem I am facing is how to Bind the RadGridView with ColumnGroupView using a DataTable or DataSet as DataSource. The Demo with respect to ColumnGroupView Doesn't Mention the above( https://docs.telerik.com/devtools/winforms/gridview/view-definitions/column-groups-view).Please Help

I need to format the background color of the Summary row based on its Aggregated (Sum) value compared to another value on the form.  If the values are equal, I want it blue, if they are not equal, I need it to be red.  

            Dim ugRow As GridViewRowInfo
            Dim dAdditionTotal As Double = 0
            For Each ugRow In radGVBuildingAdditions.Rows
                dAdditionTotal += ugRow.Cells("Addition_SQFT").Value
            Next

            With Me.radGVBuildingAdditions.SummaryRowsBottom
                If .Count > 0 Then
                    For i As Integer = 0 To .Count - 1
                        .Remove(.Item(i))
                    Next i
                End If
            End With

            If dAdditionTotal > 0 Then

                Dim summary1 As New GridViewSummaryItem()
                summary1.Name = "Addition_SqFt"
                summary1.Aggregate = GridAggregateFunction.Sum
                summary1.FormatString = "Addition Total SF {0:#,##0}"
                Dim summaryRowItem As New GridViewSummaryRowItem()
                summaryRowItem.Add(summary1)

                Me.radGVBuildingAdditions.SummaryRowsBottom.Add(summaryRowItem)
                Me.radGVBuildingAdditions.MasterTemplate.ShowTotals = True
                Me.radGVBuildingAdditions.MasterView.SummaryRows(0).IsVisible = True
                Dim dBuildingArea As Double = IIf(CLIB_MAPPS.Utilities.ConvertNULLtoDouble(Me.txtBldgNetSF.Text) > 0, CLIB_MAPPS.Utilities.ConvertNULLtoDouble(Me.txtBldgNetSF.Text), Me.txtBldgEstimatedSF.Text)
                If dAdditionTotal = dBuildingArea Then  ' dBuildingArea from another control on the form
                    'MAKE SUMMARY ROW (NOT CELL, ENTIRE ROW) BLUE
                Else
                    'MAKE SUMMARY ROW (NOT CELL, ENTIRE ROW) RED
                End If


            Else
                Me.radGVBuildingAdditions.MasterTemplate.ShowTotals = False
            End If

I attempted to do it in the ViewCellFormatting event, but this requires parsing the number back out of the formatted text and is only working with the Cell in which I placed the total.

    Private Sub radGVBuildingAdditions_ViewCellFormatting(sender As Object, e As CellFormattingEventArgs) Handles radGVBuildingAdditions.ViewCellFormatting
        If TypeOf e.CellElement Is GridSummaryCellElement Then
            Dim dArea As Double = IIf(CLIB_MAPPS.Utilities.ConvertNULLtoDouble(Me.txtBldgNetSF.Text) > 0, CLIB_MAPPS.Utilities.ConvertNULLtoDouble(Me.txtBldgNetSF.Text), Me.txtBldgEstimatedSF.Text)
            If e.CellElement.ColumnInfo.Name = "Addition_SqFt" Then  
                If dArea = CInt(e.CellElement.Value) Then   'I HAVE TO PARSE THE TOTAL BACK OUT OF e.CellElement.Value
                    e.CellElement.BackColor = Color.DodgerBlue
                Else
                    e.CellElement.BackColor = Color.Firebrick
                End If
            End If
        End If
    End Sub

is there a better way to do this?

Hello,

I am using a map with 2 layers 

And i add elements to the map like this

In this setup, tooltiptext works on pins contained on layer without cluster, but they don't on the one with cluster.

Can you tell me how can i use ToolTipText with cluster ?

Thank you

Hi,

I am zooming to particular area of the ChartView. Depending on the zoom, some lines may not be visible in the current zoomed in portion of the chart. So, the legend is displaying items that are not currently visible in the chart. I need to display legend only for the lines that are visible in different zoom/pan settings. How to achieve this?

I have a databound list, in which my object contains the following properties

DOB
FirstName
LastName

When I bind my times to the list view, the columns come out as 

DOB       FirstName      LastName

Is there a way to programmatically order the columns?

FirstName     LastName    DOB

TIA

Is it possible to use data bindings in a list view that contains both groups & multiple column lists?

TIA

Hello,

I'm coming back with a new question :).

There is a way to minimize a radform just with the titlebar and keep the windows active ?

I found the TitleBar_Minimize event handler but I don't know which options use.

step1.png the windows is active

step2.png I click on the minimize button in title bar

step3.png I have my radform active and reducted (without resizebutton), I can click on the maximum button to show the radform content.

Best regards,

Could someone help with adding the following Unicode character to a tables textbox.  I have been asked to add the following service mark character (U+2120) which resolves to "SM" to the end of a string.  For some reason when I add this and try to save the report, I am getting the following error.  "Some unicode characters in this file could not be saved in the current codepage. Do you want to resave this file as unicode in order to maintain your data?"

I need to add a string to the table cell textbox as follows "Some test for textbox (℠)"

Thanks

Dave.

I have a BindingList of a business object that I want to bind with a ListView (in detail mode).

I can change which properties get displayed (and there respective column headers) using the ColumnCreating event, but I cannot change the order of the columns.

As I understand, the binding process of ListView will use the properties in the order that they appear in code, this should have been fine, except that in case of object inheritance, the parent's class properties come after the child's class properties. In my case, I want base class properties to appear first and followed by child class properties.

Is there a way to change or affect the order that columns get created?

This would also allow me to save and recreate the order in which the columns appear, if, in future, I allow the user to reorder the columns of the ListView.

I know that I could use a DataTable to manipulate the columns beforehand, and use this as my binding source, but I would like to avoid this "conversion" between business object and DataTable.
