Here comes the solution my friend.

C#

function ChangeImage() {

        var img = document.getElementById('<%=ImageButton1.ClientID%>');
        img.src = 'Images/drag.gif';
        
    }

XML

<asp:ImageButton ID="ImageButton1" runat="server" />
    <asp:Button ID="Button1" runat="server" OnClientClick=" ChangeImage()"
        Text="Button" />

Here what i am doing is that when i click on the button i called the function changeImage to change the source of the image button image.

Good Luck !

but man I am using c#

mhamad zarif 18-Jul-11 2:44am

so what ? this is not a vb code.This is java script which is unified ! try it and see it working.

You apparently have no idea what are you using! This is ASP.NET with Javascript. You C# is irrelevant here. If you don't understand it, read on ASP.NET from the very beginning.

My 5 for this answer. OP apparently does not understand the very basics of ASP.NET, so I don't know how else to help.
