I have this code, and I just want to export all pages or a specific page from the loaded PDF in the RadPdfViewer, without saving the file to the computer.
The function RadPdfViewer.ExportPage returns a Bitmap, but when I assign the result of this function to a new variable of type Bitmap, an error occurs.
'1º Option - Work
For i As Integer = 1 To RadPdfViewer1.Document.Pages.Count
Dim guid As Guid = Guid.NewGuid
RadPdfViewer1.ExportPage(i, "C:\temp\" & guid.ToString() & ".pdf", 1, True, ImageFormat.Png)
Dim bitmap As Bitmap = New Bitmap("C:\temp\" & guid.ToString() & ".pdf")
Dim reader As BarcodeReader = New BarcodeReader With {
.AutoRotate = True,
.TryInverted = True
}
Dim result As Result = reader.Decode(bitmap)
If result Is Nothing Then Continue For
Dim decoded As String = result.ToString().Trim()
If decoded Is Nothing Then Continue For
If decoded <> TextBox1.Text Then TextBox1.Text = TextBox1.Text & vbNewLine & vbNewLine & decoded
bitmap.Dispose()
My.Computer.FileSystem.DeleteFile("C:\temp\" & guid.ToString() & ".pdf")
Next
'2 Option - Dont Work
Dim bitmap As Bitmap = RadPdfViewer1.ExportPage(1, 1, False, ImageFormat.Png)
'3º Option - Dont Work
For Each bitmap As Bitmap In RadPdfViewer1.ExportPages(1, False, ImageFormat.Bmp)
Dim reader As BarcodeReader = New BarcodeReader With {
.AutoRotate = True,
.TryInverted = True
}
Dim result As Result = reader.Decode(bitmap)
If result Is Nothing Then Continue For
Dim decoded As String = result.ToString().Trim()
If decoded Is Nothing Then Continue For
If decoded <> TextBox1.Text Then TextBox1.Text = TextBox1.Text & vbNewLine & vbNewLine & decoded
Next
Hello,
RadRibbonBar avec le thème Fluent (RadRibbonBar with Fluent theme)
En ajoutant la commande pour faire disparaitre le menu, l'onglet se positionne au début.
(By adding the command to make the menu disappear, the tab is positioned at the beginning.)
CAST(THIS-OBJECT:RadRibbonBar:GetChildAt(0):GetChildAt(5), Telerik.WinControls.UI.RadApplicationMenuButtonElement):Visibility = Telerik.WinControls.ElementVisibility:Hidden.
Si je change de thème (Desert) l'onglet se positionne pas au début (comme sur le thème Fluent).
(If I change the theme (Desert), the tab is not positioned at the beginning (as on the Fluent theme).)
Best regards
Hello,
How do i make the item appear only once in the popup when the theme is Desert?
1 - Without Theme
2 - Desert Theme

Hello Support Team.
I have an application with a PropertyGrid in C# with WinForms. Is it possible to have a CheckedListBox to allow multiple selections in the PropertyGrid?
Thank you in advance.

Hi,
in VirtualGrid, is there a way to set the default filter descriptor (different from "contains")?
Something like you suggest for the Grid control (https://www.telerik.com/forums/how-to-set-default-of-filterdescriptor-operator).
Thank you,
Emanuele
