Form Combobox1 Changing Text in Combobox2

PowerShell Help
1

I have created a form that gets data from a JSON config file. The first combobox gets a list of departments as listed in the JSON file. Based on what is selected from combobox1, combobox2 should list the titles associated with the selected department. I have the basics created and can get this to work, however, it is not user friendly.

The only thing I want my IT users updating is the JSON file. They should not have to update the Powershell. What I am having an issue figuring out is how to tell Powershell what department is selected and what titles to get out of the JSON file based on that.

Here is what I got so far.

I have that working. What I am wanting to avoid is hard coding the departments within the Powershell script.

Scratch my last reply. I thought what I was looking at was the same thing, just coded differently. I see the difference now, but cannot get it to work. Can you go into a little more detail on the PowerShell portion?

 

Never mind, I figured it out. I replace the following lines 124-139 with:

$cb_department_change = { $selectedDept = $cb_department.SelectedItem foreach ($dept in $configfile | Where{ $_.Department -eq $selectedDept }) { $titles = $dept.Groups.Titles | Sort-Object Title } $cb_title.Items.Clear() $cb_title.Text = $null $titles.Title | foreach { $cb_title.Items.Add($_) } } $cb_department.add_SelectedIndexChanged($cb_department_change)
