I have a RadListBox full of items. I have two buttons "Up" and "Down" to move items around the RadListBox. So if I have an item selected in the box and click the Up button then it swaps the currently selected item with the one above it. Here's the code, it's very simple:
My problem is with the last line. The SelectedIndex part highlights the correct item, but a black rectangle stays around the previously selected item. I've tried refreshing the control, setting the focus, etc... What do I need to do to get the black rectangle to follow the SelectedIndex item?
Chris
| Dim selIndex As Integer = RadListBox.SelectedIndex |
| If selIndex <> 0 Then |
| Dim selItem As String = RadListBox.Items.Item(selIndex).Text |
| Dim aboveItem As String = RadListBox.Items.Item(selIndex - 1).Text |
| RadListBox.Items.Item(selIndex - 1).Text = selItem |
| RadListBox.Items.Item(selIndex).Text = aboveItem |
| End If |
| RadListBox.SelectedIndex = selIndex - 1 |

Just wondering if this is another known Telerik bug, or something I'm doing wrong? Looks like I can't even use Telerik Shaped Forms without getting errors!

[Sorry this should have gone into the menu strip forum]
Hi
Please would it be possible to add the MergeIndex property to the RadMenuSeparatorItem (or RadMenuItemBase) so that it will be possible to control the insertion point of a menu item when using the Telerik toolstrip in a CAB application.
I have extended your base class for now, but I thought it should be something that you are aware of and consider adding to your code base.
Thanks
Marek

Private Sub RadButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton2.Click
'Executes Ping.exe -t With RadComboBox1 as Variable
With Me.RadComboBox1
If Not Me.RadComboBox1.Items.Contains(Me.RadComboBox1.Text) Then
.Items.Add(RadComboBox1.Text)
End If
End With
Process.Start("\pingdev.bat", RadComboBox1.Text)
This code works with the VS combobox - I'm trying to figure out what I'm doing wrong -
I get this error -
Value type 'String' cannot be converted to 'Telerik.Wincontrols.RadItem
Can anyone help?
Thanks!

I've added a textbox into a RadToolStrip that I would like to be able to use for searching. I would like the user to be able to type a search value into this textbox and then hit Enter and then I'll handle the appropriate event and kick off the search.
In addition to the code that was automatically generated by the designer, I added the following 3 lines of code (hoping to catch any one of these 3 events, but would prefer to get the KeyDown):

this.searchTextBox.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.searchTextBox_KeyPress);
this.searchTextBox.KeyDown += new System.Windows.Forms.KeyEventHandler(this.searchTextBox_KeyDown);
this.searchTextBox.KeyUp += new System.Windows.Forms.KeyEventHandler(this.searchTextBox_KeyUp);
I then added the methods specified within the handler code above and added simple code in each to just show a message box. I also added breakpoints in each of these methods. When I run my application, I don't see any message boxes when typing into the text box, and my breakpoints are never hit either.
Any suggestions? Are these 3 events supposed to fire for the RadTextBoxElement within a toolstrip?
Thanks,
Ben

I need to add a list of items to a radlistbox control, and I can do it fine with the MS version, but this does not work. I am using the following syntax:
Me.RadListBox2.Items.Add("test11")
Me.MediaListVisible.Items.Add("test11")
Can anyone give me some examples please?
Thanks in advance..
Me.RadListBox2.Items.Add("test11")
Me.MediaListVisible.Items.Add("test11")

Hi
The grid seems to slow down alot when I have a few checkbox columns and I display the grid fullscreen. I've testing by removing and adding columns using the column chooser, and the grid is only slow when the check box columns are present.
I am binding a a generic list to the grid.
I am doing the following when initially creating the grid (setting the columns to readonly), and removing this code does improve that responsiveness

to a shaped form, i added a panelbar with a few groupelements. i toggled one of the groupelements to EnableHostControlMode.
initially i was able to add a treeview to the groupelement in question; however, when i ran the app it flickered really bad and then crashed after i tried to collapse the groupelement.
now it's to the point to where i can't even toggle the groupelement to EnableHostControlMode without crashing the VS IDE.
ultimately, i want to add treeviews to groupelements and have no flickring.
thanks....
