Find a Combobox Item

[Natasha]

My RadComboboxItem is composed for two textbock. I need to find an element only by the content of the second textbock.
Name of the first text box is Ident.
Name of the second text box is content.

Change: I have attached the code

Hello Natasha,
this requires a coded solution. I've attached the test that gets the job done. Here's the actual code I use with comments explaining each line of code:

String textBoxToSearchFor = "new 4";

            Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ToggleDropDown(); //Open drop down.
            //We access a pre-generated variable to access the element because we added it to the Elements Explorer
            //http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/elements-pane-overview.aspx


            //Go through each item in the combobox and find the one that hold the required textbox
            foreach (Telerik.WebAii.Controls.Xaml.RadComboBoxItem cbi in  Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ItemElements) {

             try {  //We use try/catch because Find.ByTextContent throws an exception when it doesn't find what it's looking for.
                cbi.Find.ByTextContent(textBoxToSearchFor); }
            catch (Exception e) {
             continue;   //Move on to the next item if the TextBox was not found inside of this one
            }

            cbi.Select(); //Select this item if the Exception was not thrown (i.e. Find found what it was looking for)
            }

I hope this helps, let me know if you have any additional questions.

Hi,
In your solution the tool the search for element in both textblock (indent and value).
I just want to search in combobox "value".
Thanks for your help.

[Stoich]

Hi Natasha,
this requires a very minor change. The value TextBlock has the following tagname:

<TextBlock Name='content' AutomationId='content' Uid='34476226'>

So we need to verify that the element we want to select has that AutomationId. Here's the code that does it:

if (!cbi.AutomationId.Equals("content")) { continue; } else //If AutmationId does not match value TextBlock, move on
            {
            cbi.Select(); //Select this item if the Exception was not thrown (i.e. Find found what it was looking for)
            }

Here's how this integrates in the complete coded step:

String textBoxToSearchFor = "new 4";

            Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ToggleDropDown(); //Open drop down.
            //We access a pre-generated variable to access the element because we added it to the Elements Explorer
            //http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/elements-pane-overview.aspx


            //Go through each item in the combobox and find the one that hold the required textbox
            foreach (Telerik.WebAii.Controls.Xaml.RadComboBoxItem cbi in  Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ItemElements) {

             try {  //We use try/catch because Find.ByTextContent throws an exception when it doesn't find what it's looking for.
                cbi.Find.ByTextContent(textBoxToSearchFor); }
            catch (Exception e) {
             continue;   //Move on to the next item if the TextBox was not found inside of this one
            }

            if (!cbi.AutomationId.Equals("content")) { continue; } else //If AutmationId does not match value TextBlock, move on
            {
            cbi.Select(); //Select this item if the Exception was not thrown (i.e. Find found what it was looking for)
            }

            }

Hi Stoich,
I noticed this solution is very slow. For a combobox with 50 comboboxItem the solution delay is 4 minutes.
You have any idea how minimize the delay???

[Stoich]

Hi Natasha,
the slowness is there because we're waiting for this:

cbi.Find.ByTextContent(textBoxToSearchFor);

to timeout which takes about 10 seconds.

We can change the so-called 'Find Strategy" in order to change this and speed things up. Check out the following blog post on setting Find Strategy:
http://blogs.telerik.com/blogs/posts/10-06-24/silverlight-test-automation-changing-the-element-find-strategy-to-avoid-timeoutexecution-2578840260.aspx

The new code should look like this:

String textBoxToSearchFor = "new 4";

            Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ToggleDropDown(); //Open drop down.
            //We access a pre-generated variable to access the element because we added it to the Elements Explorer
            //http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/elements-pane-overview.aspx


      // save the original strategy to set it back at test end
            FindStrategy originalStrategy = app.Find.Strategy;

  // reset the find strategy
                app.Find.Strategy = FindStrategy.WhenNotVisibleReturnNull;




            //Go through each item in the combobox and find the one that hold the required textbox
            foreach (Telerik.WebAii.Controls.Xaml.RadComboBoxItem cbi in  Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ItemElements) {


              if (  cbi.Find.ByTextContent(textBoxToSearchFor) != null) {


            if (!cbi.AutomationId.Equals("content")) { continue; } else //If AutmationId does not match value TextBlock, move on
            {
            cbi.Select();
            app.Find.Strategy = originalStrategy;
            break;
            }

            }
        }

Hi Stoich,
This solution didn't find the element.
I send you my code and the test.
Thank you.

[Stoich]

Hi Natasha,

I reworked the code so that you don't need to change the Find Strategy. Currently setting Find Strategy doesn't seem to work 100% as expected which causes the code I sent you not to work. Here's the revised code:

// Navigate to : 'http://localhost:11960/SilverlightApplication2TestPage.aspx'
            ActiveBrowser.NavigateTo("http://localhost:11960/SilverlightApplication2TestPage.aspx");
            app = this.ActiveBrowser.SilverlightApps()[0];

            // radcombobox: drop down 'Open' action.
            String textBoxToSearchFor = "val6";

            Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ToggleDropDown(); //Open drop down.
            //We access a pre-generated variable to access the element because we added it to the Elements Explorer
            //http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/elements-pane-overview.aspx

            //Go through each item in the combobox and find the one that hold the required textbox
            foreach (Telerik.WebAii.Controls.Xaml.RadComboBoxItem cbi in  Pages.SilverlightApplication2.SilverlightApp.ComboRadcombobox.ItemElements) {

          //      FrameworkElement fwe = cbi.Find.ByText(textBoxToSearchFor);
                   FrameworkElement fwe = cbi.Find.ByExpression(new XamlFindExpression("textcontent="+textBoxToSearchFor));

            if (fwe != null)
                {
                    Log.WriteLine("Found "+fwe.ToString());

                    if (!fwe.AutomationId.Equals("content")) {
                        Log.WriteLine("Found desired text but not in 'content' textbox");
                        continue; } else

                        {
                        cbi.Select();
                        break;
                        }
                }

        }

Test is attached.
