Our documents have a couple of images included (they are in rtf format, with some images in the header).

In Word, depending on the status (started, validated, ...), we take one image from the document and show it as a watermark. The other ones we hide.

I'm trying to do the same with the editor, but i can't really find api's to just get a list of images in the Document.

Is there a way to do this ?

Hello all.  I'm trying to figure out how to configure a summaryrow to evaluate only the selected rows when multiple rows are selected.  The evaluation event handler would need to fire and update the summary total each time the selected rows collection changes.  So far I have not been able to find any examples of this behavior.  A point in the right direction will be appreciated. 

I have tried working with the "CustomSummaryItem" from the forum but this only fires the evaluation event once and doesn't summarize changing selections- it only evaluates the first row in the grid.  I have this small bit of code posted below and my alteration is in bold.  I suspect I need to subscribe to some other (less documented) method.

Thanks in advance - Mike

I found this class in the forum ----------------------------------

Public Class CustomSummaryItem
    Inherits GridViewSummaryItem
    Public Sub New(ByVal name As String, ByVal formatString As String, ByVal aggregate As GridAggregateFunction)
        MyBase.New(name, formatString, aggregate)
    End Sub

    Public Overrides Function Evaluate(ByVal row As IHierarchicalRow) As Object
        Dim itemsummary As Decimal = 0
        For Each childRow As GridViewRowInfo In row.ChildRows
            If childRow.IsSelected Then
                itemsummary += CDec(childRow.Cells("miles_driven").Value)
            End If
        Next childRow
        Return itemsummary
    End Function

End Class

I am using the following code in the currentpagechanged event to update a spin editor, but the spin editor value does not stay in sync with the Navigator text box when changing pages via the Navigator or clicking on the thumbnails.  

private void radPdfViewer1_CurrentPageChanged(object sender, CurrentPageChangedEventArgs e)
        {
            try
            {
                seFrom.Value = int.Parse(this.radPdfViewerNavigator1.CurrentPageTextBox.Text) ;
            }
            catch
            {

            }
        }

I have a RadForm. I added a RadImageButtonElement (CreatingButton.png) to the Title Bar of it because I want to add a Login type of button.

1.) How can I get that button to behave like the Minimize/Maximize buttons in terms of like when I hover over the button, it changes it's appearance the same way like in the attached MinimizeAppearence.png?

I tried to use EnableHighlight, HighlightColor properties, but it didn't seem to work. It had no effect.

2.) Is there a way when I click on the RadImageButtonElement and I signed in already to have something that looks like the way Microsoft Word does it (WordSignIn.png)?

Thanks in advance.

2-how to get value cValueMember = "Id" to insert database

I set the datasource to a query ( CatQuery)

This loads the control with 2 columns- serialID and catText

How do I get these two values of the selected item of the dropdown.  

Thank you

This is probably a very trivial issue, but - just starting with UI for Winforms - I am unable to access the data apparently loaded in the workbook below  (what I am trying to do is to load an excel file in a Worksheet to use it in a datatable)

When I run this, it goes well, but the only output displayed by the Debug.Writeline instruction is :

 "> Telerik.Windows.Documents.Spreadsheet.Model.RangePropertyValue`1[Telerik.Windows.Documents.Spreadsheet.Model.ICellValue]"

Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click

        Dim fileName As String = "C:\Users\patrick\testfile.xlsx"
        Dim MyWorkbook As New Telerik.Windows.Documents.Spreadsheet.Model.Workbook
        Dim WorkbookFormatProvider As New XlsxFormatProvider()
        Dim MyInput As New FileStream(fileName, FileMode.Open)
        MyWorkbook = WorkbookFormatProvider.Import(MyInput)
   
        Dim MySheet As Worksheet = MyWorkbook.Sheets.ActiveSheet
        RadSpreadsheet1 = MyWorkbook.Sheets

        Dim Res As String = MySheet.Cells(1, 1).GetValue().ToString
        Debug.WriteLine(" > " & Res)
       
    End Sub

Can someone be kind to tell me what I do wrong ?

Thanks
