Update: Ignore this post or close it. The problem was not the RadComboBox itself.

Best regards

Martin

Hi,

I've a RadComboBox inside a UserControl with the DropDropStyle=DropDownList. I added three elements and after that I selected the third one:

radComboBoxItems.Add(new RadComboBoxItem("1", 1));
radComboBox.Items.Add(new RadComboBoxItem("2", 2));
radComboBox.Items.Add(new RadComboBoxItem("3", 3));
radComboBoxSelectedValue = 3;

I also tried:

radComboBoxSelectedIndex = 2;

In both ways the the SelectedIndex is correct and when the ListBox appears the correct item is selected. But the ComboBox itself doesn't display the selected item. The funny thing is, that the same code works fine on a Windows Form. So, what's the problem there.

Regards

Martin

Radmenu as mdi child forms do not maximize when loaded

Hello,
i'm having a crazy time trying to get my child forms to be maximized.

i have: windows form as mdi parent - windowstate set to maximum.
on it is a radmenu.
i have a child windows form in which the windowstate is set to maximize.

i do the below code to load the child:

        

frmCPBase.MdiParent = Me
frmCPBase.WindowState = FormWindowState.Maximized 
gsResize(frmCPBase, frmCPBase.pnlMain) 
frmCPBase.Show() 
  
    Public Sub gsResize(ByVal aoForm As Form, ByVal aoPnl As Panel) 
        Try
            '* Center the MDI Child 
            If aoForm.WindowState = 2 Then      'maximized 
                Dim yInt As Integer = Screen.PrimaryScreen.WorkingArea.Height / 2 - aoForm.Height / 2 
  
  
                aoForm.Location = New Point(Screen.PrimaryScreen.WorkingArea.Width / 2 - aoForm.Width / 2, 120)  
                If aoForm.Location.X < 0 Then
                    aoForm.Location = New Point(0, aoForm.Location.Y) 
                End If
                If aoForm.Location.Y < 0 Then
                    aoForm.Location = New Point(aoForm.Location.X, 0) 
                End If
                If aoForm.Left < 0 Then
                    aoForm.Location = New Point(0, aoForm.Location.Y) 
                End If
            End If
  
            '* Center the frame 
            If aoForm.WindowState = 2 Then
                aoPnl.Location = New Point((aoForm.Width / 2) - (aoPnl.Width / 2), (aoForm.Height / 2) - (aoPnl.Height / 2)) 
            Else
                aoPnl.Location = New Point((aoForm.Width / 2) - (aoPnl.Width / 2), (aoForm.Height / 2) - (aoPnl.Height / 2)) 
            End If
  
        Catch ex As Exception 
  
        End Try
  
    End Sub

but when i run, the child is NOT maximized. when i maximize the mdi form (running by clicking the control max button on the mdi form), THEN the child form is maximized.

i did this with another menu - exactly the same only NOT using the radmenu and it works fine. is there something in the radmenu you need to set for this??

thanks for ANY help - i'm about to get rid of the telerik radmenu...if i cannot resolve. i have it set up as the "main menu=true"

i have the radmenu set up as:

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _

Partial Class frmMain

Inherits System.Windows.Forms.Form

'Form overrides dispose to clean up the component list.

<System.Diagnostics.DebuggerNonUserCode()> _

Group without a sort?

We have a set of report types with a defined display order. For example, we want the Customer Reports, then the Financial Reports, then the Accounting Reports. Is there a way to group without sorting on the grouped column? I tried passing a null in for the sort order, but that just sorted ascending.
Thanks!

DataSet, GridView DataBinding to Parent Information

Hi,

I have setup a dataSet with 3 tables Locations,Customers and Orders. I have setup 3 relations "Locations to Customers" , "Locations to Orders" and "Customers to Orders"

I have a form that has two GridViews one to show All the Customers and one to show the Selected Customers Orders.

I have done this by:

MainForm.DataSource = FormData;

MainForm.DataMember = "Customers";

SubForm.DataSource = FormData;

SubForm.DataMember = "Customers.Customers_Orders";

Is there anyway I can bind a column to the Locations Description from the Locations table via the "Locations to Customers"/"Locations to Orders" in the relative grids?

Dropdown Multi-line Textbox

I am a new(will be official by the end of the week) Telerik customer that is migrating from DevExpress. I have, obviously, been impressed so far but I have come across a concern. My app makes extensive use of DevEx's "Dropdown Multiline Textbox control and I have not seen a similar control for Telerik so far. Am I missing it or would I have to create it myself by embedding the Textbox into a Dropdown control? If so is there any guidance on that?

While this isn't a deal breaker it will be a bit of a downer if the first thing I have to do after purchasing a $1300 Custom Control suite is build my own custom control....

Thanks for any help and direction that can be provided.
