I am adding a set of images on Page_Init, and on some button click I want to update those images. For some reason it doesn't work. why?
This is my code:
[Code]....
I can see that ButtonSubmit finds the correct control and changes its property, but on the response to the client I still see the old image.
in my page_load method I call a mthod that it create some dynamic controls. one of them is an Image control that it's ImageURL property set to an URL that is saved in data base. image shows that URL but when postback ocuurs, previous image controls doesn't their image. but other controls for example TextBoxes keep text values. what should I do for keep image url property for this dynamic Images controls?
View 3 RepliesI'm writing a script and need with being able to modify the ImageUrl property in a HyperLink control from the code behind page. It is meant to dynamically show an image.
I just need to know the correct format of the code behind to get this to work.
I am realitivly new to c# and I am trying to do something that is probably simple, but I might just be over thinking it.What I want to do is have an image change based on a return of a sql data call. I am using a stored procedure that reads values and uses a case to switch between red, yellow, green for status. For example, I have nine items that the SP goes through and returns one of the colors. What I would need is if it detects a red, change the image to red and so forth. Now, when I execute the SP in C# I can get the data but it always just reads the last value. So if it had a red in there and the next one is a green, it uses the green. I even thought about reading the colors and using an IF statement adding the values to determine which color should be used.

I am attaching an image to a listview from code behind, the image depends on a value from the database and there are 5 different images.It sometimes works fine and then will randomly come up with an error, when nothing has changed, the error is:[Code]....
It doesn't seem to make sense to me because ImageUrl IS a member of image. Here is my code:

I've got an image URL in a gridView which retrieves the name of a file, but I need to add some text to the start and end of the value returned. This is the code so far:
[Code]....
The image URL renders as 'filename.png', but I need to add 'about-us/images/' before it.
I have an update panel with an image control inside. At some point in JS I try to assign the image source, by doing
$("#pvwImage").attr("src", imageSrc);
The image refreshes correctly and shows me the assigned image. However when I click on a button that raises a postback, by the time it gets to the server the ImageUrl property of the image is still the default one, so my changes in JS didn't have any effect.

My code works fine when running it on my pc, but when I uploading it to the server, I always get the same error, I can't delete file I have just assigned into imageurl. However I able to delete it before using Image1.ImageUrl = sOldFileName; Somehow the server doesn't release sOldFileName after assignment it into imageurl. Here is the code, it's a pop up that gets the a variable from another page as a QueryString. The image blocks on the page load, before clicking the btnCrop_Click button.

I save the Image*URL* to the database and im trying to change part of my listview so I can display that image, every attempt ive tryed either results in server tag not well formed if I use an asp image or only the url path being displayed if i use a html img control. How can I combat one of these so I can display images via a imageurl in my listview?

I have an image inside a repeater, and I would like to change its IMAGEURL based on parameter that's being passed to it.
<asp:Repeater ID="Repeater" runat="server">
<HeaderTemplate>
<asp:Image ID="imgType" runat="server" />[code]....
There is a SWITCH statement in the code behind that is altering the IMAGEURL depending on what's being passed to it. Inevitably, however, the images ID ("imgType") is not visible to the SWITCH statement (presumably because it's inside a REPEATER).
I am trying to load an image in my webpage from a file server where all of our images will be held.I set the imageurl property on the image control to dynamically;;
image1.ImageUrl =photo+"//"+image1.jpg;(Here photo is a string that value is: "//server/DBV/Documents/Employee/phot")
and I can see the image perfectly fine in IE.
However, the image does not show in Firefox. In Firefox it is just a blank screen when i am using developer tools that image button is in there but it showing faded in developer tool(firebug).in screen nothing showing only blank.
I am working with two different web sites in asp.net. In the first project i upload some images to a specific folder under the project root and save just the filename in the database, now i am trying to display this images at some page of the second project I know the filename from the database and the image folder as absolute pat but I have not been able to display the image, even thought when looking in firebug the image src is correct src="D:/MyFolder/image.jpg" the image does not display, probably because it is not pointing in the right directory. I have also tried using Server.MapPath and then my D location but still no success.
View 3 RepliesI have an image ItemTemplate within a FormView, where the ImageUrl is the photo_file_name. However, I want to add "~/uploads/" at the begining of the photo_file_name.
Below is the code:

So for example, if the photo_file_name is Jellyfish.jpg I want it, the ImageUrl to be ~/uploads/Jellyfish.jpg without having to change the photo_file_name in the DB.
I am working on a job portal. I have an Organization picture that I have to Save & Retrieve . My image saving code is working perfectly. But I am dumping the images in my D drive. Now when I use
Image1.ImageUrl = @"D:DirecotyPathImage.jpg";
I does not render an image on the front end...
What can be done in this situation? And are there any alternatives to that?
I am using asp:image to bind image in datalist itemTemplate. but it does not bind i mean the image does not displayed. my source is:

I have a image control (image1) on a .aspx page and I'm trying to pass in a file system path (not a url) on my Page Load event:

is there a way to manipulate a piece of a File path in a ImageUrl of an asp image?
Ex: <asp:Image ID="helpButton" ImageUrl="images/HelpButtonsA/buttons/help.png" runat="server"/>
I would like to change HelpButtonsA dynamically to HelpButtonsB(assuming that the path "images/HelpButtonsB/buttons/help.png" exists.) Can it be done by setting a public variable in the code behind then using that variable in the path?
I must be missing something very basic here.I have an asp:Image control where Visible="false." The idea is that I don't want the image to be displayed unless there is a value in a database column that contains a value for ImageURL, in which case my code behind switches visible to "true"But in IE8, these image controls are displaying as broken images, even when Visible="false". Why is that? And how do I fix this?.aspx:

I've basically got 2 applications. One is my back office application (Admin) and the other , the front end application (web site)
My problem is that, the admin uploads 'n' number of photos ,which is stored in one of the folders within my back office application and the path is stored in my DB as , for example : ~/Uploads/test.jpg.
But it is not possible for me to access this image from my front end application because the path actually exists in my back office app. How do i get to view the images that I uploaded on my front end Appn. ?
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:

in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.
View 3 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");
}
}
I am using .net 3.5 c#
i have this asp:Image
<asp:Image id="Imgage1" runat="server"></server>
I tried to load image from server side when page load
like this
Image1.ImageUrl = "~/mine.jpg";
But it did not work.
I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.
I put a detalist in my vb.net web page. And bind with datasource, how can i bind a dynamical path on....
