Iterate thru DataRepeater (VB.Net PowerPack)

Question

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.

Answer 1

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);
   
   }
   

Answer 2

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.

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);
    }
