Is it possible to mimic an <hr> tag in the Html markup functionality?  Trying to create dividers in the RadLabel control.  Has anyone implemented something similar?

Thanks!

I'm using RadSpreadsheet with the ribbon bar to display a generated Excel workbook.  Users want to save the workbook via the Save ribbon button, but they want a default filename in the save dialog (not "book1.xlsx").  I can't figure out how to get there from current documentation and other forum questions.  Please advise.  Hoping I can access it without overriding the whole framework that already does most of the work for me.

Hi,

When form loads scroll bar missing as well as summary also missing but when i resize the form it appear and work appropriately.
I believe this is some visual glitch. Please provide me some solution for this.
I am attaching gif image which ca explain you my concern.

Check the below attached zip file for more reference.

Hi,

I'm looking into the viability of using the WinForms RadSyntaxEditor for a small project.

I think I've come across a bug when it comes to DPI scaling.

The component itself seems to work fine with DPI scaling except for the search/find functionality. When you search for some text and click to go to the first instance it finds, the actual text is off screen, though it is highlighted correctly (when you scroll down you can see it highlighted).

If I set the CaretPosition manually to a line further in the document, it also displays correctly so it seems to be specifically limited to the  built-in Search/Find panel.

This is easy to replicate by changing Windows display scale to anything other than 100%.

we are using the RichTextEditor to display a DOCX file. HOwever, I can not for the life of me figure out to remove/close the document once it has been assigned to the Document property on the RichTextEditor control. I know this is probably simple, but I am just not seeing anything like a CLOSE(), EXIT(), CLEAR() and Setting Document = null crashes.  

 

TIA

Hi,

I try to add checkboxes to page.

I try to this code, but it is not working:

var nve = this.radNavigationView1.NavigationViewElement;
                foreach (var item in nve.Items) {
                    RadCheckBoxElement cb = new RadCheckBoxElement();
                    cb.ToggleStateChanged += cb_ToggleStateChanged;                
                    item.ButtonsPanel.Children.Add(cb);
                }

Thanks in advance!

 

I have a Form with 4 group boxes each containing 2 radio buttons - Yes and No - obviously each set mutually exclusive. The IsChecked properties of each are bound to boolean values. All 8 properties are set to false. However, when the form displays, the first Yes button is checked. Even when I unbind them and explicitly set them all to false, the first option is set t true.

s there any way for all buttons to be set to false?

Thanks

Hi,

 

Is it possible to use paging and just retrieve data for each page (i.e if you go to a new page the data for that page will be loaded)?

 

The issue i'm having right now is that the result from the server (currently with WCF) has contain all the records in order for the paging to work, however, I dont want to send all the data at once.

 

Maybe there is a way to manipulate the TotalPages-property to think it has more data in the result?

I have a RadWizard control in my project and I set the BackColor property to a custom color. Whenever I make any changes to the code in the cs file of the RadWizard the BackColor property resets to white. Is there some reason this may be occurring or is this a bug?
