The following is the text of the OP's first version of this question

Hello Friends

I've tried to develop multicolumn combo by using combination of following controls for client requirement

1.Textbox
2.Repeter
3.Ajax DropDownExtender

Now I can view multiple columns in the control I've created using Repeater & can also select any item from repeater and that item will be displayed in TextBox.Right now text box is read only.

Now I want to implement following things :

1.Suppose I am typing "abc" in textbox then all items start with "abc" should be displayed in Repeter.This should be done with AJAX.

2.And when I remove "abc" then all item should be display.

How can I achieve this ?

I am attaching my control.

If any one knows how to implement this then please modify solution and send me back.

-Thanks
