Web Forms :: How To Change The Imageurl Of An Image Field On Mouseover Of An Imagebutton

Mar 30, 2010

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");
}
}

AJAX :: Change Image Source Of An ImageButton At MouseOver?

Jan 4, 2010

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.

Web Forms :: Change ImageURL Of ImageButton1 When ImageButton2 Has Mouseover?

Mar 23, 2010

I am working with ASP.NET VB using Visual Studio 2008 and yes, I am new to ASP.NET. This is what I am trying to do.

I have a form with 6 controls.

The first is a large ASP imageButton control called ibtnDisplay with a imageURL set to "Pic1.jpg", then there are 5 smaller imageButtons called ibtnThumb1 through ibtnThumb5 each with a imageURL set to "Pic2", "Pic3" and so on.

When ibtnThumb1 has a mouseover event I would like to change the image in ibtnDisplay to the image in ibtnThumb1, so from "Pic1" to "Pic2".

I have found many leads on how to change the image in the same control, for instance when the mouse is held over ibtnThumb1, I can change the image to a different picture in the same control. how to change the image on a different control.

Web Forms :: Change Image In ImageButton Every 3 Seconds?

Mar 31, 2010

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"

Forms Data Controls :: Mouseover On Imagebutton Inside Gridview Templatefield Triggers Server-side Events In FF?

Feb 3, 2011

In a gridview I have a TemplateField containing an imageButton defined as:

<asp:TemplateField>
<HeaderTemplate>
HeaderName
</HeaderTemplate>
<HeaderStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:ImageButton ID="imgName" ImageUrl="./img/img.png" runat="server" style="cursor: crosshair;" OnClick="imgName_Click" />
</ItemTemplate>.......

Now the odd thing at run-time is, whenever a client-side mouseover event is triggered, the app does a full postback. That happens only in firefox.
