Trying create a simple image rollerover with an imagebutton in a panel on a masterPage.  OnMouseOver Change Image and OnMouseOut change image back to original image.  This seems complicated.  Research has pointed me in a couple different directions that I don't think work.  And neither seems to work.  If someone could point me in the right direction I would appreciate it. 

 1.  

"ibImage" ImageUrl="~/b.jpg" runat="server">

[...]

protected void Page_Load(object sender, EventArgs e)
{
ibImage.Attributes.Add("onmouseover", "this.src='s.jpg'");
ibImage.Attributes.Add("onmouseout", "this.src='b.jpg'");
}

        "server"
            ImageUrl="images/banana.jpg"
            BorderWidth="0.2cm"
            BorderColor="Gainsboro"
            onmouseover="this.src='images/mango.jpg';"
            onmouseout="this.src='images/banana.jpg';"
            onclick="Button3_Click">

perhaps try

ibImage.Attributes.Add("onmouseover", "this.src='/images/s.jpg'");
ibImage.Attributes.Add("onmouseout", "this.src='/images/b.jpg'");

as in the two code samples above you are mixing:  no paths, using the ~, and relative pathing

it's just easier to use virtual pathing, which doesn't involve the .NET engine at all, so that your generated HTML always knows where to go.....

I have tried removing ~ and / and vice versa.  The mouse over event is definetely firing.  Like you said it just seems to be a problem with my path.  works fine in examples on the web like below, but haven't been able to get it to work in VS2005.  Is this a VS2005 thing and will work or what?

Might seem silly to check, but:

1) Have you looked at the generated HTML to make sure the attributes did indeed get added?

 2) Have you tried to put something like an "alert()" statement in there instead of changing the src?

Hi,

It works great for me:

..

        <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/Images/1.JPG" /></div>

 ...

    protected void Page_Load(object sender, EventArgs e)

    {

        ImageButton1.Attributes.Add("onmouseover", "this.src='Images/2.JPG'");

        ImageButton1.Attributes.Add("onmouseout", "this.src='Images/1.JPG'");

    }

The Image files are under Images/ folder in my example. Please check this.
