Question

I am working on a Windows form Application.
I want to check/uncheck all checkboxes in checkedlistbox.

I am using following code to generate checkboxes dynamically.

    var CheckCollection = new List<CheckedBoxFiller>();
    foreach (DataRow dr in dt.Rows)
        CheckCollection.Add(new CheckedBoxFiller {
                                Text = dr["ImageName"].ToString(),
                                Value = dr["ImageId"].ToString()
        });
    chklbEvidenceTags.DataSource = CheckCollection;
    chklbEvidenceTags.DisplayMember = "Text";
    chklbEvidenceTags.ValueMember = "Value";

And this is the CheckboxFiller class

private class CheckedBoxFiller {
    public string Text { get; set; }
    public string Value { get; set; }
}

Now I want to check/Uncheck all checkboxes. How can I achieve this?

Any help would be useful.

Answer 1

I found solution.

 for (int i = 0; i < chklistbox.Items.Count; i++)
      chklistbox.SetItemCheckState(i, (state ? CheckState.Checked : CheckState.Unchecked));

state is boolen value.
