    I have a test where I'm first verifying that a button is enabled, then I click that button and it changes to a RadListBox.
    I can verify that a particular item = index 1 or whatever, but I can't seem to click an item to select.

    On Record, the step is added to the test:

    RadListBoxItem('ctl00_ContentPlaceHolder1_lstMyTeam_i1'): '
    Australia' action -> 'Select'

    but on running the test it fails at this line with

    '16/08/2011 2:23:46 p.m.' - 'Fail' : 7. RadListBoxItem('ctl00_ContentPlaceHolder1_lstMyTeam_i1'): 'Australia' action -> 'Select'------------------------------------------------------------Failure Information: ~~~~~~~~~~~~~~~Object reference not set to an instance of an object.InnerException:System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.WebAii.Controls.Html.RadListBoxItem.Select() at Telerik.WebAii.Design.Translators.Html.ListBox.RadListBoxItemActionDescriptor.Execute(Browser browser) at ArtOfTest.WebAii.Design.Extensibility.HtmlActionDescriptor.Execute(IAutomationHost autoHost) at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.ExecuteStep(Int32 order)

    Is there anything that I need to check or any setting i need to change in order to be able to select an item in a RadListBox?

    Hi Cheryl,

    See below an example which works at our side:

           public void MoveUp()
               RadListBox listBox = Find.ById<RadListBox>("RadListBox1");
               Assert.AreEqual("Amelie", listBox.Items[1].Text);
               Assert.AreEqual(true, listBox.Items[1].Selected);
               Wait.For<RadListBox>(myListBox => myListBox.Items[0].Text == "Amelie", listBox, 5000);

    Does it work at your side?
    Could you please send us a sample .aspx page which contains your RadListBox declaration or a live url to examine the problem locally?

    hi Helen

    I'm looking for a way to select and radlistbox item by text in a webform?

    So far I have:

                var userListBox = CurrentManager.ActiveBrowser.Find.ById<RadListBox>("~lstUsers");
                var TestViewerItem = userListBox.FindItems(x => x.Text=="test.viewer").First();

    The problem is it keeps hanging at line 2, var TestViewerItem.

    Hello Eric,

    Are you certain there's an item in your ListBox where the text matches "test.viewer"? I adapted Helen's code to include your sample and it worked as long as I used matching text for one of the list items.

    If you continue to have difficulty, please provide a public site that I can run your code against directly and see the issue first-hand.
