Hello Daniel,
Thank you for writing.
You can introduce a public property returning the
RadCheckBoxElement. Afterwards, you can iterate the AutoCompleteBoxViewElement.
Children collection and find the checked
TokenizedTextBlockElements:
public Form1()
{
InitializeComponent();
this.radAutoCompleteBox1.CreateTextBlock += radAutoCompleteBox1_CreateTextBlock;
this.radAutoCompleteBox1.AutoCompleteDataSource = this.customersBindingSource;
this.radAutoCompleteBox1.AutoCompleteDisplayMember = "ContactName";
this.radAutoCompleteBox1.AutoCompleteValueMember = "CustomerID";
}
private void radAutoCompleteBox1_CreateTextBlock(object sender, Telerik.WinControls.UI.CreateTextBlockEventArgs e)
{
if (e.TextBlock is TokenizedTextBlockElement)
{
e.TextBlock = new MyTokenizedTextBlockElement();
}
}
public class MyTokenizedTextBlockElement : TokenizedTextBlockElement
{
private RadCheckBoxElement checkBox;
public RadCheckBoxElement CheckBox
{
get
{
return this.checkBox;
}
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(TokenizedTextBlockElement);
}
}
protected override void CreateChildElements()
{
base.CreateChildElements();
int index = this.Children.IndexOf(this.RemoveButton);
this.checkBox = new RadCheckBoxElement();
this.checkBox.StretchVertically = true;
this.checkBox.StretchHorizontally = false;
this.checkBox.Checked = true;
this.Children.Insert(index, this.checkBox);
}
}
private void radButton1_Click(object sender, EventArgs e)
{
foreach (MyTokenizedTextBlockElement item in this.radAutoCompleteBox1.TextBoxElement.ViewElement.Children)
{
if (item.CheckBox.Checked)
{
Console.WriteLine(item.Item.Text);
}
}
}
I hope this information helps. Should you have further questions, I would be glad to help.
Regards,
Dess
