Error in PDFFormatProvider when exporting HTML with incorrect URLs

Hi, I'm having the following problem. When calling

pdfProvider.Export(document, stream);

where pdfProvider is PdfFormatProvider and document is RadFlowDocument, I sometimes get an Illegal Path exception with this stack trace:

at LS.TMMsgViewer.Services.PdfGenerator.ExportToStream(Stream stream) in C:\ls\pvminiserver\LS.TMMsgViewer\Services\PdfGenerator.cs:line 63

The HTML contains this fragment, I suspect the URL in the "src" attribute is what's causing the problem:

Is there a setting to ignore malformed URLs (instead of crashing)?

Thanks.

Change ReportViewer font at run time

Hi

is it possible to change the font in the ReportViewer at run time ?

Did it in the RadGridView at run time with the following code and functioned:

Private Sub RadFontDropDownList1_TextChanged(sender As Object, e As EventArgs) Handles RadFontDropDownList1.TextChanged

Dim fnt As Font

fnt = RadGridView1.Font

RadGridView1.Font = New System.Drawing.Font(RadFontDropDownList1.SelectedFont, RadDropDownList2.Text)

End Sub

I would like to change the font in the RadGridView that it also

in the ReportViewer.

Use the RichTextEditor to edit the source?

Hi

Is it possible to use the RichTextEditor (in WinForms) to edit the source/the formatting of the rich text? Much like the HTML view of the comparable ASP.Net control?

There are sometimes when it is hard to understand why some formatting are applied specially when doing copy-and-paste.

I found the ToggleFormattingSymbolsCommand but while it is showing some code, it doesn't show them all and doesn't make the editing easier.

Add row in a hierarchy structure

I have a radgridview element where I need to programmatically insert a new row into the child structure of a certain parent row. The behavior would be the same as if I add a row from the add new row (UserAddNewRow). The final result should be equivalent to the row 'NEW ROW' in the attached image.

Thank you.

e.CellElement.Value

Hi

I have the following code ..

Private Sub RadGridView1_CellFormatting (sender As Object, e As UI.CellFormattingEventArgs) Handles RadGridView1.CellFormatting

If e.CellElement.ColumnInfo.Name = "Document" Then

e.CellElement.ForeColor = Color.Red

Else

e.CellElement.ResetValue (LightVisualElement.ForeColorProperty, ValueResetFlags.Local)

End if

If e.CellElement.ColumnInfo.Name = "Document" Then

If e.CellElement.RowInfo.Cells ("Document"). Value> = RadTextBox4.Text And e.CellElement.RowInfo.Cells ("Document"). Value <= RadTextBox5.Text Then

e.CellElement.DrawFill = True

e.CellElement.BackColor = Color.Yellow

e.CellElement.ForeColor = Color.Blue

e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Radial

e.CellElement.Font = New Font ("Book Antiqua", 12.75 !, FontStyle.Bold)

End if

End Sub

works perfectly !

Now I would like to add only the sum in the "Document"

column that only e.CellElement.BackColor = Color.Yellow or also e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Radial have.

I would like to have this sum displayed in radlabel3.text, how do I get it there?

CellValueChanged not firing with pasted value

In the following thread I received help on creating a subclassed TimePicker bound to a TimeSpan CLR type:

http://www.telerik.com/community/forums/winforms/gridview/timepicker-column-in-radgridview-at-runtime.aspx

The app is using this custom editor to enter default personnel schedules. It would be very labor-saving to copy the ArriveTime and/or DepartTime on Monday and simply paste it into the corresponding cell in the rows below. That is my goal, and the users' wish, but it is not working for the following series of reasons:

I am marking the row as "dirty" (i.e. needs to be persisted) in the CellValueChanged event and then later testing to see if the row is dirty in the RowValidating event, and if so, I save it to the database. The aim here is to avoid much unnecessary database i/o; only "dirty" rows are written to the database. However, the paste operation does not cause the CellValueChanged event to fire, and so the row is never marked as having been changed.

QUESTION: Is there a code change I can make to the TimePicker that would cause a paste operation to fire the CellValueChanged event?

void DFGRID_CellValueChanged(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

{

e.Row.Tag = "dirty";

}

Trigger form key events from editor

Hello. I searched for similar problems in the threads but can't find one that solves my problem.

My form's KeyPreview property is set to true, and I have a code for Form_KeyDown event as follows:

private void Form_KeyDown(Object eventSender, KeyEventArgs eventArgs)
{
...some code
}

Now, when I press the ESC key inside one of the cells in edit mode, I expect the Form_KeyDown event to fire. But in this case, it does not. It only fires when the grid is not in edit mode.

How can I automatically trigger these form key events from the editors, without manually calling them from CellEditorInitialized?

Thank you in advance.
