I have a radgridview which is bound to a dataset.
When the user sorts the radgrid, the dataset is not sorted equally so it does not give the correct data back for editing.

Is there a solution to that ?

Read-only Columns/Rows/Cells

Is there a way to make specific columns, rows or even certain cells read-only in the grid on the side of the gantt chart. For example, I don't want users to be able to edit the name or dates of a task directly in the grid. Instead I want the user to have to double click on a line in the grid to bring up a window where they can edit those details.

Import rtf into radrichtextbox

Hi,

How can we import rtf into RadRichTextbox. We got the following code.

public RadDocument ImportDocx()

{

RadDocument document = null;

IDocumentFormatProvider provider = new DocxFormatProvider();

OpenFileDialog openDialog = new OpenFileDialog();

openDialog.Filter = "Documents|*.docx";

openDialog.Multiselect = false;

DialogResult dialogResult = openDialog.ShowDialog();

if (dialogResult == System.Windows.Forms.DialogResult.OK)

{

using (FileStream stream = new FileStream(openDialog.FileName, FileMode.Open))

{

document = provider.Import(stream);

}

return document;

}

But, it is not working. It is crashing while it tries to create the stream.

Please help us on this.

RadPrintDocument - Header Overlapping Content

Hi,

I'm having a problem with setting a header in a radprintdocument. I'm setting a leftheader only. It looks fine on the the first page, but on further pages, it prints on top of the content of the document -- as in, the content and the header start at the same point on the page, instead of the content being printed below the header.

Here's my code:

        Header = "Date: " & lblDateTime.Text & " To: " & txtTo.Text

        If txtCC.Text <> "" Then
            Header = Header & " CC: " & txtCC.Text
        End If

        Document.LeftHeader = Header
        Document.DefaultPageSettings.Landscape = False
        Document.DefaultPageSettings.PrinterSettings.Copies = 1
        Document.AssociatedObject = txtEmail
        Document.PrinterSettings.PrinterName = Printer

        Document.Print()

Add event handler for HyperlinkOpening

How do I add event handler of HyperlinkOpening for hyperlink column field in C#? I saw the following code but I cannot link it to radgridview. I can add event via property windows for radgridview but don't know how to do it for 1 column only. Thanks.

Private Sub RadGridView1_HyperlinkOpening(sender As Object, e As HyperlinkOpeningEventArgs)
    e.Cancel = True

    Dim f As New Form()
    f.Text = e.Column.Name + " " + e.Row.Index
    f.Show()

End Sub

The disappearance of the child template

Hello there,

I believe I've found a bug in gridview. After adding a childtemplate (1) to a childtemplate (2) of the mastertemplate, any change to the grid will 'disconnect' childtemplate (1) from childtemplate (2).

To work around, add the following in your *.designer.cs after the changes:

this.gridTemplate2.Templates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] {

this.gridTemplate1

});

Of course, this is incredibly annoying to do every time you change the grid, so I'm hoping another solution is possible.

Excel Addin SelectedItem gets nulled/destroyed

Hello,

there seems to be a problem with the DropDownList (latest version, the last 2015 version worked fine) when used inside a Excel AddIn.

A demo project is attached (not a png it's a zip file), you need Excel 2013 or 2016 installed to debug the demo project.

When you run this, there is a new ribbon tab in the Excel (tab2) and a new button (button1) to click.

If you take the same code from the RadForm2 and make a new WinForms Project and do the same thing as in the Excel AddIn, the code works fine.

Kind Regards,

Christian
