View 2 RepliesI am designing a webpage with some ASP ImageButtons. They work fine with jpegs but fail with tiffs. Is there any way round this?

I have an ImageButton where I want to change Image every 3:rd second. (When pressing the button a browser will open with an URL with is the functionality I am after also) For the moment I do use this method with a Timer and it works fine except for one thing.
Every time the image change you can see in the bottom of the browserwindow, this message: "Downloading http://...... 1.jpg" etc....
It just "blinks" and it goes very fast but still it is kind of annoying in the long run...
So I wonder if I can find a better solution or if it is possible to Turn off this message to not be seen ?: "Downloading http://...... 1.jpg"

how to change the imageurl of an image field when I mouseover an imagebutton in a gridview? both the imagebutton and image urls are the same location.
I'm doing this in code behind but I can't seem to get the Image1.Imageurl to change to the same ImageUrl the imagebutton is pointing to.
C#
protected void ImageButton1_PreRender(object sender, EventArgs e)
{
ImageButton imageButton1 = (ImageButton)sender;
if (imageButton1 != null && string.IsNullOrEmpty(imageButton1.Attributes["onmouseover"]))
{
imageButton1.Attributes.Add("onmouseover", "Image1.ImageUrl=imageButton1.ImageUrl");
}
}
I've created an image for my imageButton, but when applied, it renders using a different size to the original, making it display smaller than the original??

View 5 RepliesI would like to change the image on animageButton as this is clicked by the user.
when the master page is loaded it shows the btnHome.ImageUrl = "~/images/home.jpg";

The imageButton should change from a selected image to nonselected.
I have a simple web page which contains an ImageButton. I wanted to know that is there any way for me to change the ImageSource of this ImageButton while the Mouse is over the element.
I used to change it as follows:
OnMouseOver="src='image/image.gif';"
I want this image to change through a duration.
for example, if you want to change a background image, you use:
<Animation>
<OnMouseOver>
<Style Action Attribute="Background Image" duration=".5" FPS="24" value="images/image.gif" ></Style Action>
</OnMouseOver>
<Animation>
I need to know how to change the imagebutton image on mouse over.
I have a list view configured to show data from a table. Below is this code for the ItemTemplate:
<ItemTemplate>
<td id="Td2" runat="server">
<table border="0" width="300">
<tr>
<td style="width: 25px;">
</td>
<td style="vertical-align: middle; text-align: right;">
<a href='TrackDetails.aspx?TrackID=<%# Eval("TrackID") %>'>
<asp:Image ID="Image1" runat="server" ImageUrl="~/Catalog/Tracks/Images/<%# Eval('CDImageLocation') %>" AlternateText='<%# Eval("CDImageLocation") %>' Height="80" Width="80" />
</a>
</td>
<td style="width: 250px; vertical-align: middle;">
<a href='TrackDetails.aspx?TrackID=<%# Eval("TrackID") %>'><span class="ProductListHead">
<%# Eval("tName")%></span><br>
...
</ItemTemplate>"
The trouble is the image is not showing up. I have used this code on other projects and it worked well. For some reason the Eval function is not evaluating the image location, yet in the alternate text it workd just fine.

I have put in dynamic (from db) image alts for images shown on my site, and when i check the page source i can find the alt tags all working fine.
However, google doesnt seem to be finding them, and i have tried an online tool which searches for image alts, and it is unable to find them.
I am assigning alts in a datalist, on item_databound - is this where i am going wrong?
At what point should I assign the image alts so that google can see them?

The above code contains an image tag in header of the master page..
whenever I open a new web form linked with this master page.. the existing image doesn't open or isn't displayed..
And one more ques... the overall contents of the web pages are moving beyond their original locations after being run the program.. whereas the contents are in their own locations before execution.. How can I make them static to view??
