Ignore accent in autocomplete ComboBox

[Guillaume]

Hi, 

I am trying to find a way to ignore the accents entered in the combobox with the autocomplete function.

If someone enter "René" as text, the function I used to populate the combobox won't use the accent and the actual filter used will be "Rene".
But as a result that none of my result contains an accent, nothing is displayed in the comboxbox, except the number of results  found.

Is there any way for the combobox to not use the accent in the filter ?

Thanks !

Hello Guillaume,

The RadComboBox does not support such functionality by design. However, I would suggest you to implement a LoadOnDemand functionality and the desired functionality, by handling the event handler (ItemsRequested) and getting the typed characters and then returning the desired results.

Can you make a example please.?

Hello Arcella,

You can simply replace the é character with e in the filter string, which is accessible in the ItemsRequested event handler. Please consider the below implementation:

protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
   {
       var searchString = e.Text;
       searchString = searchString.Replace("é", "e");

       List<RadComboBoxItem> list = new List<RadComboBoxItem>();

       for (int i = 0; i < 20; i++)
       {
           list.Add(new RadComboBoxItem("Cent" + i.ToString()));
       }

       var filteredFileSet = list.Where(item => item.Text.Contains(searchString));

       RadComboBox1.DataSource = filteredFileSet;
       RadComboBox1.DataTextField = "Text";

       RadComboBox1.DataBind();
   }
