Capture selected ListViewItem with Openedge

[Mark]

Hello, I'm using Openedge 11.6. How do I go about capturing the selected item in a RadListbox and display it in another field? There is only 1 column and the details in the List are programmatically loaded. What I have below is displaying the Listbox object and not the selected items.

 

@VisualDesigner.
method private void radListView1_Click( input sender as System.Object, input e as System.EventArgs ):
    this-object:radtextbox2:text = cast(sender, Telerik.WinControls.UI.RadListView):text.
     return.
end method.

 

Also, is there a resource available with sample code for Openedge Visual Designer developers?

Thanks

Mark

Hello Mark,

Thank you for writing. 

You can use the SelectedItem property for this:

this-object:radtextbox1:Text = this-object:radListView1:SelectedItem:Value:ToString().

Currently, our documentation contains only examples in C# and Visual Basic. However, this should not stop you to examine our documentation and search for the desired functionality. 

I hope this will be useful. Let me know if you have additional questions.

Thanks Dimitar! It works but not exactly as I wanted though. I believe I need to use the method SelectedItemChange to display the row I am selecting. I moved the code you provided, it does work but now it's giving me an error(see below) just before the text is displayed in the field.

@VisualDesigner.
method private void radListView1_SelectedItemChanged( input sender as System.Object, input e as System.EventArgs ):
           this-object:radtextbox2:Text = this-object:radListView1:SelectedItem:Value:ToString().
return.
end method.

Error:

Lead attributes in a chained-attribute expression(a:b:c) must be type HANDLE or a user-defined type and valid (not UNKNOWN). (10068)

 

What do you think?

Thanks

Hi Mark,

You should check if the SelectedItem is null first:

METHOD PRIVATE VOID radListView1_SelectedItemChanged( INPUT sender AS System.Object, INPUT e AS System.EventArgs ):
    IF  this-object:radListView1:SelectedItem NE ? then DO:
         this-object:radtextbox1:Text = this-object:radListView1:SelectedItem:Value:Tostring().
    End.
    RETURN.
END METHOD.

Please let me know if there is something else I can help you with.
