Help - Exporting RadRichTextBox document to a MemoryStream causes an OutOfMemoryException

Hi there,

I'm having a Word document (6MB) which has 11 pages with image.

I'm using RadRichTextBox to load it into and then export it to a MemoryStream, then I got an OutOfMemoryException.

Here is the code sample:

IDocumentFormatProvider pdf = DocumentFormatProvidersManager.GetProviderByExtension(ext);
pdf.Export(radRichTextBox1.Document, stream);

When debugging, I observed that the stream is quite big (33MB). Could you please let me know why the stream is really big like that.

How can I fix the issue?

Filter window for GridViewDataColumn does not have a owner hence causes the window to stay when we switch to other windows

The Filter window that shows up when we invoke the Filter button does not disappear when we switch to other windows. As a result, this cause the Filter window does not close though we come back to the UI and click anywhere in the Grid. Normally, when we click anywhere in Grid when the filter window is open, the filter window disappears. But when we switch to any other window other than the active window, this causes the Filter window to not close on clicking anywhere in the GridViewDataColumn. I believe the issue here is that the owner window for the Data GridViewDataColumn is not properly set nor the window is displayed as Modal. Hence this issue is happening. Could you please provide a fix or suggest a workaround for this issue ?

Thanks,

Grid Cell not keeping edit change

I have a RadGridView control that is being populated from a WCF service and if I set the autogeneratecolumns=True, when I enter the cell and change the contents, it changes works fine; however if I set it to false it reverts back to the original content of the cell. I want to be able to control which columns display

My WCF service returns the data into a datatable.

                             <telerik:RadGridView  Name="grd1" AutoGenerateColumns="False" Width="1000" Height="100" CanUserFreezeColumns="False">         
                        <telerik:RadGridView.Columns >         
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding ItemCode}" Header="ISBN" UniqueName="ItemCode" />         
                        </telerik:RadGridView.Columns>         
                    </telerik:RadGridView>         
                     

I tried adding the column in XAML and doing it in VB.NET and when autogen is false -- it won't keep the change.

Is there some other code behind that I need to do to make the cell change stay ?

                            Dim VenCode As String         
                    If cbVendor.SelectedValue = "*" Then VenCode = "%" Else VenCode = cbVendor.SelectedValue         
                    Dim sqlCmd As String         
                    sqlCmd = "SELECT TOP 100 PERCENT dbo.ToBeReturned.ItemCode , dbo.Inventory.Title as Description, " _         
                            & "dbo.ToBeReturned.Qty, upper(RTRIM(Ltrim(dbo.ToBeReturned.RtnVendor))) as Vendor, dbo.ToBeReturned.Invoice, " _         
                            & "dbo.ToBeReturned.InvoiceDt, dbo.ToBeReturned.Discount, dbo.ToBeReturned.Price as Cost, " _         
                            & "UPPER(dbo.ToBeReturned.RtnVendor) as orgVendor FROM dbo.ToBeReturned " _         
                            & "INNER Join dbo.Inventory ON dbo.ToBeReturned.ItemCode = dbo.Inventory.ItemCode Where Vendor Like '" & VenCode & "'"         
                    '//ieData.AddPrm("@myKey", pType.pString, "ARC", True)         
                    '//ieData.FindQry("QryFindCat")         
                    ieData.ChangeQry(sqlCmd)         
                    Dim column As New GridViewDataColumn()         
                    column.DataMemberBinding = New Binding("ItemCode")         
                    column.Header = "ISBN"         
                    column.UniqueName = "ItemCode"         
                    Me.grd1.AutoGenerateColumns = False         
                    Me.grd1.Columns.Add(column)         
                    grd1.ItemsSource = ieData.dt

ToolWindow HeaderTemplate

Hi everyone,

For some reasons, I made some changes on Header for undocked/floating window (called ToolWindow) editing ToolWindow template and modifying it.

As you can see on attached file, I increased font size, header height (rectangle was 22, now 48), changed colors etc...

Everything look fine BUT I can only drag the window clicking on the upper part on the header (actually I think the first 22 pixels). The new header height value is not taken in account and I don t know what to do.

Here is my changes:

</Border>

Thanks in advance for your help

Trial Version Question

I just downloaded the trial version to see if the new dlls will be better than the old ones we were using.

In the dll we have (2013) Edit Template / Edit a copy is always disabled and it is preventing us to customize the style easily

With the trial version I see the same problem. Is it because it is the trial version?

Or the problem is something else.

We are in the process of buying new licenses.

Thanks

PDF Export - WatermarkText problem

Hi everybody,

when i export a document to pdf without a watermark, the there are no problems.

But when i add a watermark text and then try to export it, then the program crashes.

Here i create a draft document.

private void CreateDraft()

{

WatermarkTextSettings watermark = new WatermarkTextSettings();

watermark.ForegroundColor = Colors.Gray;

watermark.Opacity = 1.0d;

watermark.RotateAngle = 315.0d;

watermark.Text = "Vorabexemplar";

this.rtbResult.SetWatermarkText(watermark);

this.UpdatePdfViewer();

}

After adding the watermark the pdf viewer needs to be updated to set the results:

private void UpdatePdfViewer()

{

RadDocument doc = this.rtbResult.Document;

var pdfProvider = new PdfFormatProvider();

var outputStream = new MemoryStream();

pdfProvider.Export(doc, outputStream);

this.rtbResult.UpdateEditorLayout();

this.pdfViewer.DocumentSource = new PdfDocumentSource(outputStream);

this.pdfViewer.DocumentSource.Loaded += (s, e) => { outputStream.Close(); };

}

Everthing works fine without watermark. With watermark the programm crashs on line pdfProvider.Export(doc, outputStream);

I've also tryed the solution in the following thread without success Mail Merge - PDF Export - Watermark problem

Full error message
