Hi Jorgen,
Thank you for writing.
To properly restore the items you need to recreate the same data source and assign it to the autocomplete box. The following example shows how you can save and restore the items using simple csv file. The
MyItem class just contains two properties (text and value). The code adds all the items to the autocomplete box when the data source is restored. This is achieved with the
Text property:
private void radButton1_Click(object sender, EventArgs e)
{
selctedItems = radAutoCompleteBox1.Text;
var csv = new StringBuilder();
foreach (var item in (BindingList<MyItem>) radAutoCompleteBox1.AutoCompleteDataSource)
{
var first = item.Text.ToString();
var second = item.Value.ToString();
var newLine = string.Format("{0},{1}{2}", first, second, Environment.NewLine);
csv.Append(newLine);
}
File.WriteAllText("test.csv", csv.ToString());
}
private void radButton2_Click(object sender, EventArgs e)
{
BindingList<MyItem> data = new BindingList<MyItem>();
string text = "";
var reader = new StreamReader(File.OpenRead(@"test.csv"));
while (!reader.EndOfStream)
{
var line = reader.ReadLine();
var values = line.Split(',');
data.Add(new MyItem()
{
Text = values[0],
Value = int.Parse(values[1])
});
text += values[0] + ";";
}
radAutoCompleteBox1.AutoCompleteDataSource = data;
radAutoCompleteBox1.AutoCompleteDisplayMember = "Text";
radAutoCompleteBox1.AutoCompleteValueMember = "Value";
radAutoCompleteBox1.Text = text;
}
Could you please check the above code and see if it is suitable for your case? If not could you please specify how this approach is different from your real one?
I am looking forward to your reply.
