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)
        {
           
            
        }

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.

I want to rename column, for example from gridViewTextBoxColumn9 to col_Name and then get access from code.

Instead dataGridView1.Columns["col_Name"].IsVisible = true I want to write col_Name.IsVisible = true

It is possible?

Hi,

I just noticed a terrible bug when trying to bind a list of business objects on a DropDownList :

Setting the DataSource erases both property values previously set on the designer.

Setting the DisplayMember through code works but as soon as I try to set ValueMember, it erases DisplayMember and doesn't set ValueMember either !!

        ddlLines.DataSource = lineService.GetAllLines();
        ddlLines.DisplayMember = nameof(Line.LineName);
        ddlLines.ValueMember = nameof(Line.LineId);

Here is the class :

public class Line
{
    [BrowsableAttribute(false)]
    public int LineId { get; set; }

    [DisplayName("Souche")]
    [Column(Order = 0)]
    public string LineName { get; set; }
}

This happens on a DropDownList inserted on a form and also inside a RibbonControl

Is this serious ??

Hi all.

Question: is it possible to translate (back and forth) mouse coordinates in RadPdfViewer to PDF coordinates on the relative page?

I do not need location inside Telerik internal document representation nor on screen but on the PDF representation for interoperability with other tools.

What I mean by PDF coordinates: a coordinate system where the unit is 1/72th of an inch, having the origin (coordinate 0,0) at the bottom left of the page, and X Y increase toward the top right corner, for example an A4 bottom left coordinates are (0,0) top right  (597.6 , 842.4) 

The desired effect would be something like

public (int pageNo, float pdfX, float pdfY) GetPdfCoordinates(RadPdfViewer viewer,  Point mouseEventLocation){
public (int pageNo, int X, int Y) GetViewerCoordinates(RadPdfViewer viewer, int page, float pdfX, float pdfY);

Reasons: I am currently using other libraries only for that specific purpose but the telerik pdf viewer is just as good except for this important feature that allows software to interoperate with third parties PDF tools.

Thank you all.
