Solution 1

AutoCompleteBox is made up of TextBox and few components. The control does not expose the TextBox control. So you cannot achieve your idea unless you derived and customize the control.

Derived AutoCompleteBoxEx from AutoCompleteBox and add a public Property/Method to return the TextBox used inside the control. Then you can try the below example.

Try,

C#

textBox.CaretIndex = 0;

after you selected the item from the AutoComplete box

hi I got solution before week itself ,the Autocomplete box is composed of many things among that textbox is also one ,so we need to get the textbox from the autocomplete by traversing the tree

Inside the last focus of autocomplte box we can put like

AutoCompleteBox autoObject = sender as AutoCompleteBox;
         TextBox textObject = VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(autoObject, 0), 0) as TextBox;
         textObject.SelectAll();
         textObject.SelectionLength = 0;

so that the begining part of text will be diplayed on autocomplete last focus

Cheers,
