Background:

https://docs.telerik.com/devtools/winforms/knowledge-base/how-to-embed-chrome-browser-in-a-winforms-application

Refer to the documentation above to embed chromium browser in WinForm.

 

Problem statement:

Whenever I embed the CefSharp Web Browser, the formatting changed. 

Observation - With embedded CefSharp Web Browser: 

  • Window State set to Maximized but it won't start with Maximized state.
  • The formatting of the words seems changed - truncated with '...'


using CefSharp;
using CefSharp.WinForms;

 

private ChromiumWebBrowser browser = new ChromiumWebBrowser(); private void frmBulletin_Load(object sender, EventArgs e) { Cef.Initialize(new CefSettings()); pnlBrowser.Controls.Add(browser); browser.Dock = DockStyle.Fill; }



Screen shot: Without embedded CefSharp Web Browser (Maximized - full screen): 

 

Screen shot: With embedded CefSharp Web Browser (around 3/4 of the screen only, the words truncated with '...'):

How to invert the text color as the progress bar fills so that the text is visible on different colors of the progress bar? For example, on a green background, the text color is yellow, and on a light gray background, the text color is black or another visible color. Like here

Hello,

I have a issue with print datagridview by a larger number of columns.

In first case (WratText = false) I cannot see all text (see image)

In the second case (WrapText = true) is row height too small and again I cannot see whole text.

Both case it has set AutoSizeRows = true;

In both cases I don't see the entire date

 Can you help me?

Thank you

Radek

Simple question: I want to change the color of some tasks, to show when they are on the critical path.

So I simply want to trigger GraphicalViewItemFormatting, which does all the coloring. At the monent, the event fires when i move the mouse over the task ,which proves it all works, but I need to trigger the re-draw from my calculateCritcalPath method.

I'm using the VisualStudio2022Dark and VisualStudio2022Light themes for my application.

I've used the waitingbar on a couple of longer loading controls (works great BTW).

However the overlay that appears over a control while waiting, always appears to be the light theme color.  On a dark theme, this is can be pretty visually jarring, especially when the associatedControl is a larger screen control.

Is there a way to set this overlay so that it uses a specific theme?  I haven't been able to get it to change at all programmatically.

On the gridview when a user enters a filter value, I would like for the background color of that filter to change to a different color (only for the column or columns where a filter has been entered) so that users can quickly see where they entered a filter value.

Currently, if the grid has many columns the user will enter a value (sometimes forget that they did that) and wonder why they have a filtered grid.  I know that sounds crazy but end users do that!  So, I'd like the Filter Cell Backcolor to be a different color so that it's Obvious that - that particular column has a filter applied to it.

Below, I show the code I'm using in the GridData_ViewCellFormatting event.  But the problem is - is that it changes the color for the entire filtering row (across all columns)... whereas I want the back color of the "Filter Cell" to change only for that particular column or columns where a filter has been applied.

It would be greatly appreciated is someone has the answer to solving this 'problem'.

Dim filterDescriptors = GridData.FilterDescriptors
If TypeOf e.CellElement Is Telerik.WinControls.UI.GridFilterCellElement Then
    DirectCast(e.CellElement.RowInfo, Telerik.WinControls.UI.GridViewFilteringRowInfo).Height = 28
    e.CellElement.DrawFill = True
    e.CellElement.NumberOfColors = 1
    e.CellElement.BackColor = Color.Beige
    e.CellElement.Font = New Font("Verdana", 10)
    For Each filterDescriptor In filterDescriptors
        Dim propertyName = filterDescriptor.PropertyName
        Dim filterOperator = filterDescriptor.Operator
        Dim expression = filterDescriptor.Expression
        Dim filterValue = filterDescriptor.Value
        If filterValue IsNot Nothing Then
            'If e.CellElement.Text = propertyName Then
            e.CellElement.BackColor = Color.LightGreen
            Exit Sub
            'End If
            'e.CellElement.BackColor = Color.Pink
        End If

I'm having a repo with multiple projects which are using Telerik components. All of them are NET9/WPF/Windows currently

All projects are merged in one large solution (Master Sln), additionally we are using solution filters which are dependent on the Master Sln

The license file for each user is placed next to the Master Sln.

Now there are

  • App1 which is using Telerik.Windows.Controls.Ribbon.For.Wpf.Xaml
  • App2 using Telerik.Windows..Controls.Data.For.Wpf.Xaml and Telerik.Windows.Controls.GridView.For.Wpf.Xaml and a few more.

In

  • App1 there is no Telerik.Licensing.Runtime copied int the output folder
  • App2 has a Telerik.Licensing.Runtime in the output folder

But

  • App1 works
  • App2 does not work, shows the "Not Licensed" dialog and renders the "Not Licensed" pattern over the application, the reason is said to be a missing Telerik.Licensing. nuget package.

 

My question is why do I need the Telerik.Licensing.Runtime at all, since it is a compile time assembly? Additionally, all nuget packages contain Telerik.Licensing as referenced transisitive assembly.

What could be the problem why it works  with App1 and not with App2.
