You do not appear to be adding the course name to your listview elements ?

If you did, thenyou need to extract the course name from the listview selection then use text blocks to do this.
(you do not show a listview selection, so difficult to advise...)

sorry i can`t understand what you meaning ...
all i want is the course name to be appeared when clicking on the course code from listview element is there any way to make that?

[TIMAI2]

Show the output of listview.selection, and indicate which part you require.

Also show the content of your courses list, and indicate which item is the course name.

But your course codes are empty!

[Naannncccyy]

I know ... it's value will be added later with apu

[ABG]

You will need to use the ListView's SelectionIndex to look up the information you want from the place where you loaded the Elements for that ListView.

I hope you kept it.

[Naannncccyy]

What are the blocks for doing what you meam?

[TIMAI2]

Get your course code data included first

Use your listview.selectionIndex block to return the index of the listview elements, then you can use this to display the course name associated with that index.

@Naannncccyy

What are the blocks for doing what you mean?

Start by showing the blocks where you load the Elements of the ListView,

[Naannncccyy]

Can you make what you mean in blocks to understand you plz
