View 4 Replieshow 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");
}
}

View 3 RepliesI 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.

I 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";
But when the user clicks on the btnHome, its ImageUrl should change to btnHome.ImageUrl = "~/images/homeSelected.jpg";
The imageButton should change from a selected image to nonselected.
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"

I'm trying to use one ImageButton as both a login button and a logout button. Initially its a login button. I click the button once and it runs the login click handler and pops up a text box to type in a password. Then I enter the password to login. Inside the password box's submit handler I check to see if the password is valid. If it is, I enable all the password protected functionality on the page, change the button's image from the login image to the logout image, and change the button's click handler from the login Click handler to the logout Click handler.
So far my code just swaps the button's image but the click handler never changes to the logout handler. I have tried two ways of changing the ImageButton's click handler programmatically and both have failed:
1.
loginBtn.Attributes.Remove("OnClick");
loginBtn.Attributes.Add("OnClick", "logoutBtn_Click");
2.
loginBtn -= new ImageClickEventHandler(loginBtn_Click);
loginBtn += new ImageClickEventHandler(logoutBtn_Click);
Neither the login text box or the login/logout button are inside an UpdatePanel. EnableViewState is set to the default of true. Does anyone see what is preventing the Click handler from being changed?

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 want the image of image button to change according to file extension . But its not working.
i have a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
ImageButton1.Attributes.Add("OnMouseOver", "this.src='mouseover.gif'")
ImageButton1.Attributes.Add("OnMouseOut", "this.src='mouseout.gif'")
what i'm trying to do now is get the mouseover image to load when you click the button and are taken to the page. i tried this but it doesn't work:
ImageButton1.Attributes.Add("OnClick", "this.src='mouseover.gif'")
ASP.NET says that the following ImageButton server tag is not well formed:
<asp:TableCell VerticalAlign="Top">
<asp:ImageButton runat="server" ID="imgAdd" src="Images/add_plus_1.gif"
onmouseout="this.src='Images/add_plus_1.gif'"[code]....
I think all the mouse event attributes are legit, so I don't know what it's complaining about.
Code Example:
$(document).ready(function() {
txtchangefunction();
});
function txtchangefunction(
$(".textCssClass").change(function () {
....});
or $(".textCssClass").bind('change', function())
both work for Chrome etc. but not IE8. no console error comes out.
i have radgrid in my asp.net web page with some columns and rows in each row i have some checkbox that they are in one column. so i have one checkbox in each row and column.
i want when the check box checked, write in header that checkbox(in that column) write the number and so in that row, write the diffrent number. i want it occure client-side.
I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.
