Add Checkboxes to ListView

[jalbao]

I have a ListView that uses multiple columns. I would like some of the columns to represent a yes/no value, so intuitively, I would like to use Checkboxes for those columns.

I attempted instantiating a Checkbox object and then adding the Checkbox to my code that adds subitems to my ListView:

Dim theCheckbox As CheckBox
lSingleItem.SubItems.Add(theCheckbox)

This doesn't work.

How do I add Checkboxes to columns in a ListView and then figure out how to grab the status of the Checkbox from a specific column?

There is a "Checkboxes" property on your listview. You can use that.

Hmm..

I am using it, but from what I can tell, the Checkboxes = true, is nothing more than a UI to select multiple records in the ListView - no different than clicking items with the control key held down.

Selected and Checked don't really have anything to do with one another. Add a button to your form, and test it with this code:

Dim li As ListViewItem
Dim s As String = "Selected:  "
Dim c As String = "Checked:  "
For Each li In ListView1.SelectedItems
       s += li.Text & ", "
Next
For Each li In ListView1.CheckedItems
       c += li.Text & ", "
Next
MsgBox(s & vbCrLf & c)

I don't think my question is clear.

I understand the difference between Selected and Checked items. What I don't understand is how to get checkboxes in multiple columns.

Using Checkboxes = true, will only allow for checkboxes in the first column. I, for example, want the Checkboxes in the first, fourth, and fifth columns.

From what I can tell, it looks as though the standard ListView control doesn't support this.

Thanks

I don't think so either. Although you might be able to get something that looks presentable.

Dim Chk As New Checkbox()
ListView.Controls.Add(Chk)


You can position it around the listview, and make it "appear" in the correct location.
