double click in listview = click on button

Question

I have a Windows form in Powershell with 2 buttons and a listview with 2 colums "Nom du collège" ($col1) and "Adresse IP" ($col2).

The listview is populated by the function "AddData" that traverses $MaListe.

If i select a lign in the listview and i click on the button "Connecter" ($btnCo), a second Windows form appear.

I'm looking for a way that when I double click on a line of the listview, it starts the Connect button event.

I voluntarily removed the Connect button event because there are many lines but if you wish I can provide it.

This is my code :

Thank you for your help.

Answer 1

You need to set FullRowSelect property of the ListView to true and handle ItemActivate event of it. Put the logic which you want to have in Click event of the function and ItemActivate event of the ListView in a single function.

Example

In the following example, by double click on an item of ListView or by selecting and item and click on Button, a message box will show text of the selected item:

Add-Type -AssemblyName System.Windows.Forms

$form = New-Object System.Windows.Forms.Form
$form.Size = "400, 300"

$listview = New-Object System.Windows.Forms.ListView
$listview.Columns.Add("Column1")
$listview.Columns.Add("Column2")
$listview.View = [System.Windows.Forms.View]::Details
$listview.MultiSelect = $false
$listview.FullRowSelect = $true
$listview.Items.Add("A1").SubItems.Add("A2")
$listview.Items.Add("B1").SubItems.Add("B2")
$listview.Location = "10,50"
$listview.Size = "350, 150"
$form.Controls.Add($listview)

$button = New-Object System.Windows.Forms.Button
$button.Text = "Button1"
$button.Location = "10, 10"
$form.Controls.Add($button)

Function DoSomething()
{
    if($listview.SelectedItems.Count -eq 1)
    {[System.Windows.Forms.MessageBox]::Show($listview.SelectedItems[0].Text)}
}

$button.Add_Click({DoSomething})
$listview.Add_ItemActivate({DoSomething})

$form.ShowDialog()
$form.Dispose()
