Iterate thru DataRepeater (VB.Net PowerPack)

I am using the winform datarepeater control from vb.net power pack.

All of the items on the repeater are readonly except for a checkbox column.

I want to iterate over the items and find out which checkboxes are checked.

I can't find a collection of datarepeateritems on the control and help is scarce.

Thanks for the help.

This was asked a while ago but just in case anyone else is looking for an answer:

for (int i = 0; i < this.dataRepeater1.ItemCount; i++)
{
    this.dataRepeater1.CurrentItemIndex = i;

    CheckBox checkBox = (CheckBox)
                this.dataRepeater1.CurrentItem.Controls["controlName"];
    bool isChecked = checkBox.Checked;
}

This approach makes it much easier to process/read any related controls on the same repeater item.

You could iterate through the Controls list (generated from template)

  1. Rename your checkbox in the datarepeater to "checkBoxUnbound"

  2. Use the below code

    private void button3_Click(object sender, EventArgs e)
{
    int i = 0;
    CheckBox unboundCheckBox;
    foreach (Control c in dataRepeater1.Controls)
    {
        unboundCheckBox = c.Controls["checkBoxUnbound"] as CheckBox;
        if (unboundCheckBox != null && unboundCheckBox.Checked)
        {
            i++;
        }
    }

    Console.WriteLine("DEBUG: checked found: " + i);

}

Why not just check the datasource of the datarepeater?

E.g. I have a datarepeater bound to a Bindingsource for Persons See button handler

    private void Form1_Load(object sender, EventArgs e)
    {
        List<Person> persons = new List<Person>();
        persons.Add(new Person { Name = "Peter", IsLocal = true });
        persons.Add(new Person { Name = "Sepp", IsLocal = false });
        persons.Add(new Person { Name = "Franz", IsLocal = false });

        personBindingSource.DataSource = persons;
    }


    private void buttonCountCheckBox_Click(object sender, EventArgs e)
    {
        int i = 0;

        foreach (Person singlePerson in personBindingSource)
        {
            if (singlePerson.IsLocal)
            {
                i++;
            }

        }
        Console.WriteLine("DEBUG: checked found: " + i);
    }
