RadGridView FontSize cannot be modified using the Fluent theme

Hello, Yoan.

Yes, as you said, the theme will affect FontSize effect. I set telerik:StyleManager.Theme=“Fluent” , its setting for FontSize is invalid.
So, how can I modify FontSize if I still use the Fluent theme?

Thanks

Different place for RadPane's headers

Hi there,

I'm new, and I'm currently trying to understand how RadDocking works.

Is there any way that I can put RadPanes' (which is a child inside of a RadDocumentHost) headers in another location?

Unable to hide/remove GridView left border line

I've been trying to use RadGridView to display a relatively simple list of data. No grouping, sorting or even selecting of cells allowed. I tried to customize it to not show any borders or grid lines and use my custom background but I seem to be unable to get rid of a single vertical line along the left side of the grid.

I've tried to do this by turning off all borders and make all of my backgrounds use the dark background color you can see in the image. (a static resource brush named "GsBackgroundDark") I tried to set the default styles of all of the element types that the grid apppears to use (GridViewCell, GridViewHeaderCell, etc). But clearly I'm missing something.

Can you tell me what else I need to do?

I have attached an image showing you what I see. What am I missing to get rid of that line on the left?

Below is the XAML I'm using

RadGridView memory leak issue

Hi Team,

We were previously using the 2017.2.614.45 version of the Telerik controls and were facing memory leak issues with RadGridView. We have hence upgraded to 2018.3.1016.45 version of the controls but still are facing the same memory leak issues.

We use RadPane which is placed in a RadPaneGroup; the pane in turn contains the RadGridView. We have handled the closed event of the RadPaneGroup wherein we do our cleanup operations(unsubscribing RadGridView events, setting DataContext as null). As stated in one of the forum posts, we also do the cleanup operations advised which is given at the end.

Please also find the memory profile report of our application when we closed the RadPane.

Kindly advise.

Regards,

Swapnil Ramteke

private void radDocking_Close(object sender, Telerik.Windows.Controls.Docking.StateChangeEventArgs e)

{

try

{

if (e.Panes.Count() == 1)

{

var pane = e.Panes.ElementAt(0);

if (pane is IDispose)

{

(pane as IDispose).Dispose();

}

pane.Content = null;

pane.Header = null;

pane.DataContext = null;

pane.RemoveFromParent();

pane = null;

// Wait for 5 seconds before garbage collection

System.Threading.Tasks.Task.Delay(5000).ContinueWith(antecedent =>

{

GC.WaitForPendingFinalizers();

GC.Collect();

});

}

catch (Exception)

How to modify displayed value of NumPagesField

Hi every body ....

I use RadRichTextBox in the following manner: first page is used (by the user) as a cover letter so that it is not included within the total count of pages. Footer of every page except first page should display page number x from y, where x is the current page number (after the first page), and y is the total number of pages minus one (the first page).

I could achieve the first value of the formatted footer using CodeBasedField, but unfortunately I couldn't modify the value returned by NumPagesField.

My question is how to modify value returned by NumPagesField so that I can display total number of pages minus one. Below there is an attachment of an image to show my requirement.

The following is my code snippet used in creating the custom footer:

Public Function FirstTemplate() As RadDocument

Dim section As New Section()

section.HasDifferentFirstPageHeaderFooter = True

section.Footers.[Default] = New Footer With {.Body = ReportFooter()}

End Function

Private Function ReportFooter() As RadDocument

Dim footerDoc As New RadDocument

Dim footerSection As New Section

Dim footerParagraph As New Paragraph

Dim footerDocumentEditor As New RadDocumentEditor(footerDoc)

footerParagraph.TextAlignment = RadTextAlignment.Center

footerDoc.Sections.Add(footerSection)

footerSection.Blocks.Add(footerParagraph)

footerDocumentEditor.InsertField(New FormattedPageNumber, FieldDisplayMode.Result)

footerDocumentEditor.InsertField(New NumPagesField, FieldDisplayMode.Result) '??? how to return total number of pages -1

Return footerDoc

End Function

Public Class FormattedPageNumber

Inherits CodeBasedField

Public Shared ReadOnly FieldType As String = "FormattedPageNUM"

Shared Sub New()

CodeBasedFieldFactory.RegisterFieldType(FormattedPageNumber.FieldType, Function()

Return New FormattedPageNumber()

End Function)

End Sub

Public Overrides ReadOnly Property FieldTypeName() As String

Get

Return FormattedPageNumber.FieldType

End Get

End Property

Protected Overrides Function GetResultFragment() As DocumentFragment

Dim pageNumber As Integer = 0

'Dim pagesCount As Integer = 0

If Me.Document IsNot Nothing Then

Dim position As New DocumentPosition(Me.Document)

position.MoveToStartOfDocumentElement(Me.FieldStart)

Dim sectionBox As SectionLayoutBox = position.GetCurrentSectionBox()

pageNumber = sectionBox.PageNumber

End If

Dim resultString As String = "Page " & pageNumber - 1 & " From "

Return MyBase.CreateFragmentFromText(resultString)

End Function

Public Overrides Function CreateInstance() As Field

Return New FormattedPageNumber()

End Function

End Class
