Hello Sebastien,
Thank you for writing.
By default,
RadAutoCompleteBox performs searching of items considering only the text. Hence, when you have duplicated names, it is normal that the first one will be selected. In order to achieve the required functionality, you can use the following approach:
public Form1()
{
InitializeComponent();
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Name", typeof(string));
dt.Rows.Add(1, "Smith");
dt.Rows.Add(2, "Smith");
dt.Rows.Add(3, "Smith");
dt.Rows.Add(4, "Brown");
this.radAutoCompleteBox1.AutoCompleteDataSource = dt;
this.radAutoCompleteBox1.AutoCompleteDisplayMember = "Name";
this.radAutoCompleteBox1.AutoCompleteValueMember = "Id";
this.radAutoCompleteBox1.ListElement.Tag = 2;
this.radAutoCompleteBox1.Text = "Smith;";
}
private void radButton1_Click(object sender, EventArgs e)
{
Console.WriteLine(this.radAutoCompleteBox1.Items.Last().Value);
}
public class CustomAutoCompleteBox : RadAutoCompleteBox
{
protected override RadTextBoxControlElement CreateTextBoxElement()
{
return new CustomAutoCompleteBoxElement();
}
public override string ThemeClassName
{
get
{
return typeof(RadAutoCompleteBox).FullName;
}
}
}
public class CustomAutoCompleteBoxElement : RadAutoCompleteBoxElement
{
protected override RadTextBoxListElement CreateListElement()
{
return new CustomTextBoxListElement();
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(RadAutoCompleteBoxElement);
}
}
}
public class CustomTextBoxListElement : RadTextBoxListElement
{
public override RadListDataItem Find(string text)
{
RadListDataItem item = this.SelectedItem;
if (item != null && this.IsMatching(item.Text, text))
{
return item;
}
for (int index = 0; index < this.DataLayer.ListSource.Count; index++)
{
item = this.DataLayer.ListSource[index];
if (this.IsMatching(item.Text, text) && this.Tag + "" == item.Value + "")
{
return item;
}
}
return null;
}
}
I hope this information helps. Should you have further questions I would be glad to help.
