Hi,

I've been searching now for hours for something that should be simple so I ask it here.

The radGridView got a area where columnheaders can be dropped. The panel has the default text: Drag a column here to group .... See also the attached image.

I want to change the height of that area but can't figure out how. Help would be appreciated.

Regards,

Daniel

I have a thread that connects to a service. All is well there. I am able to show MessageBox and forms from it.

The problem occurs when I try to plug in the desktopalert to show a message instead of using a form or MessageBox.  I get a black box down next to my task manager and if I click it I get an non response message fom windows.

How can I show an alert from a thread which isn't the main thread? I do not want to use backgroundworker and my component doesn't have Invoke() available.

Thank you.

Hello everyone!

EDIT: Also read the comment!

I'm currently moving some projects from DotNetBar to Telerik UI WinForms and trying a bit around the HTML makrup feature.

Is there a way to hook to an event to provide a custom way to resolve the "src" attribute of the "img" node, like in DotNetBar (see picture)? I searched thorugh all the assemblies using the IDE and I searched throw the forum, but yet I'm still not sure if there is maybe already an option for and I just can't find it.

With this custom handling it would be possible to use already loaded images or provide images from a custom destination e.g. from a ResX file. All my images and icons are stored in ResX files and I really want to avoid to put some of icons also as embedded ressource because they are already available within a resource file itself.

(Tagged as "Label" as "Markup" or "Html" does not exists and here I want to put the text into a RadLabel.)

I seem to spend a lot of time searching through the properties of controls, trying to find out why one looks just a little bit different from another.

Todays example:

why is the (x) button slightly out of allignment with the other three ?

Does anyone know of a way to do a comparison of all of the properties of two controls of the same type (even when those controls are LayoutControlItems) to make this easier? Telerik adds so many more properties, many of which are only visible in the Telerik property Builder UI, and that is modal, and has loads of properties to check.

Any ideas? Or is there a simpler way of doing this?

So if I wanted to modify a value (example: Visible = Collapse) in this highlighted element of RadScheduler. How do I do that?

I am trying to mousedown on a appointment in the scheduler and want to grab the EventId and place into a variable that I declared.

My Scheduler is in Timeline / Resource View mode.


 private void radScheduler1_AppointmentMouseDown(object sender, SchedulerAppointmentMouseEventArgs e)
        {
           
            
        }
Anyone?

Here is some sample code:

Imports Telerik.WinControls
Imports Telerik.WinControls.UI

Public Class RadForm1
    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        RadOverlayManager.Show(Me)
        For x = 0 To 1999999999

        Next
        RadOverlayManager.Close()
        RadMessageBox.Show("You will never see this.", "Nope", MessageBoxButtons.OK, RadMessageIcon.Info)
    End Sub
End Class

What you'll see is, the overlay will appear and disappear as expected.  However the radmessagebox will never appear. 

If you comment out the overlay lines, then the message box will appear.

Looks like a threading issue, but I'll leave that to the professionals to figure out. =)

Hi,

when I want to export datagrid to pdf I get error:

Invalid XHTML. RadGrid has to render correct XHTML in order to export to PDF. Parse error: char (hexadecimal value 0x1F) is an invalid character.: row 34411, position 13 at line: <td>60045685_0002</td>

Problem is in value 60045685_0002 - export without this value is correct.
