Export to Vector

Is there a way to export diagram to a vector type image? I only see options to export to bitmap. Also, export only includes visible image, anything that was generated outside of initial view (such as negative positions) are not rendered.

Diagram, DiagramRibbonBar, DiagramToolBox

Filling bindingsource taking too long

Hi there,

I'm having a problem loading data in gridview. It's taking too long, like 2 seconds for 5-10 rows.

I think the main problem is where i assign the bindingsource.

I'd like to know if there is any faster way to do this.

I'm using progress 4gl and OE 12.1.

I'll attach a file of what i'm doing.

Thanks.

Need to use RadGrid in code, but not on form

I need to use a RadGridView, so I can assign the DataSource.

However, when I do the following code, i get zero rows and columns. What am I missing

List<Records> data = dbc.Records.ToList();

RadGridView gv = new RadGridView();

gv.BeginUpdate();

gv.AutoGenerateColumns = true;

gv.AutoGenerateHierarchy = true;

gv.DataSource = data;

gv.EndUpdate();

When I look at the gridview, after the datasource is set, the row count and column count are zero? Again, What I am doing wrong? The only thing that is different then what we are doing in our application, is the grid is not on a FORM.

Thanks

Capturing TAB from RadTextBox

Is there a way to capture or trap when the user hits the TAB key while on the RadTextBox? I've tried various KeyPress, KeyDown, and PreviewKeyDown events but none of them seem to capture the TAB key. I've tried turning TabStop on and off on the control and turning the KeyPreview property on and off on the ShapedForm but that doesn't appear to changing anything related to this problem.

Basically I'm trying to capture the TAB key for use with a barcode scanning gun that will scan the barcode then automatically enter a TAB key after the scan. Unfortunately due to other applications that are using the barcode scanner, I'm forced to deal with the TAB key. I tried using the Leave event but that event wants to fire all the time including when the control has focus and the user clicks a button or when the control has focus and the form is being closed. I've been unable to come up with a viable solution just yet. Any help would be much appreciated!

Thanks,
-Tim

Import Docx to RadRichTextBox

Good morning, the binding with RadDocument and Docx drive me crazy.

When I click in importCommand, fires ImportDocx() correctly and file docx is imported in Rdoc property but in RadRichTextBox don´t display in view. When I clik in keyboard, the aplicacion pause in set.

This is my view model:

private RadDocument rd;
public RadDocument Rdoc
{
get { return rd; }
set {

rd = value;
              OnPropertyChanged();
       }
}
public void ImportDocx()
{
      RadDocument doc = null;
      DocxFormatProvider provider = new DocxFormatProvider();
      using (Stream inputStream = File.OpenRead(“Any File.docx"))
      {
        doc = provider.Import(inputStream);
      }
      Rdoc=doc;
}

This is my view (Xaml)

<telerik:DocxDataProvider RichTextBox="{Binding ElementName=radRichTextBox}" Docx="{Binding Path=Rdoc, Mode=TwoWay}"/>
<telerik:RadRichTextBox x:Name="radRichTextBox"/>.......
