I have a MDI form and trying to open the child screen. On the MDI screen I have a RadMenu on the top. When I load the app and pick a child fr the first time it loads correctly and is maximized, but when I open another child screen I close the current and then open the new screen and maximize the screen but it opens like the rad menu is not on the screen, so I lose the top section on the screen. I have not has this issue before. I am using framework 4.6.2 and I am using Telerik controls 2018 r2. I have not had this issue before.

CustomFiltering and default FilterRow together

Hi everyone,

my trial period is almost over and I really like Telerik components.
There is just one little thing that I have issues with.

Let CustomFiltering and the default Filter via FilterRow work together.
I read examples about achieving this goal under C#, but I can't figure out how to make this work under VB.

Can anyone please help me?

Thank you in advance!
Bye

How to change WaitingBar Style in Q1 2011?

Hello,

I wanted to change my WaitingBar style via examples in documentations but my waiting bar didn't have the WaitingStyle property!
So I think this is because of my Telerik version: 2010.2.10.713

How can I write this code in my version if it is supported in this version?

this.radWaitingBar1.WaitingStyle = Telerik.WinControls.Enumerations.WaitingBarStyles.Dash;

Find / Replace in Header and Footer

I'm attempting to replace the use of MS Word in our application and I'm having trouble with one of the functions we need. We use DOCX templates and fill them with data from our application. Using Office Interop, I can set the header, footer or main document as the "SeekView" before a find replace like this -

WordApp.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekCurrentPageHeader

WordApp.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekCurrentPageFooter

WordApp.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekMainDocument

Is there any function for the RichTextEditor that can allow me to perform a find/replace on the header and footer? I can only get the find/replace code to work on the main body.
