Hii This code is working fine as per your requirement "cmb" IsTextSearchEnabled= "True" IsEditable= "True" HorizontalAlignment= "Left" VerticalAlignment= "Bottom" Width= "120" TextBoxBase.TextChanged= "ComboBox_TextChanged" Margin= "0,0,0,287" Height= "33" /> private void ComboBox_TextChanged(object sender, TextChangedEventArgs e) { cmb.ItemsSource = from item in Get() // get is your item source where item.ToLower().Contains(cmb.Text.ToLower()) select item; cmb.IsDropDownOpen = true; } private List Get() { return new List () { "Ram" , "shyam" , "Moti" }; }

Add these two properties to your combobox IsTextSearchEnabled = true . IsEditable = true . Bind you Combobox to datasource and it should work.

have you tried like below "cmb" IsTextSearchEnabled= "True" IsEditable= "True" TextBoxBase.TextChanged= "MyMethod" /> string _prevText = string.Empty; private void MyMethod( object sender, TextChangedEventArgs e ) { foreach ( var item in cmb.Items ) { if ( item.ToString().StartsWith(cmb.Text) ) { _prevText = cmb.Text; return; } } cmb.Text = _prevText; }
