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.

Sachin Singh · Answer

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;
}
