Is there a way I could dynamically add a Image1 to the while loop in the below code (contained within the div) By this I mean actually adding an asp image to the div? via the code. At the moment as I see it the code looks for an asp image but Ive seen no way you can "add" it to my dynamic content:
using (OdbcCommand cmd = new OdbcCommand("SELECT Wallpostings FROM WallPosting WHERE UserID=" + userId + " ORDER BY idWallPosting DESC", cn))
{
using (OdbcDataReader reader = cmd.ExecuteReader())
{
var divHtml = new System.Text.StringBuilder();
while (reader.Read())...........
i have an image and an imagebutton, they are inside a listview and get their imageurl from databinding, i would like to know, if maybe the databinding value is empty, instead of showing a big red x, is there anyway to maybe make it link to a default image when the value is empty instead?
However, if I change the text of the LinkButton in the code-behind, I lose the image.
btnTest.Text = "New book name"
I have tried removing the LinkButton's controls in the code-behind and recreating the image along with changing the text, but it still doesn't work. I get either the image or the text but not both.
btnTest.Controls.Clear() Dim NewImage As New Image With NewImage .Height = Unit.Pixel(8) .ImageUrl = "~/DropDownArrow.png" .Width = Unit.Pixel(10) End With btnTest.Controls.Add(NewImage) btnTest.Text = "New book name"
How can I change the text in the code-behind and still retain the image as well?
I just want to add and attribute called "pubID" to an image button with the value I give it and then call that value on the image button click event. This image button was created dynamically as well. At the moment this code is not working. When debugging it looks like Pubid is getting assigned a value but on the click event, the attribute isn't being retrieved correctly.
As you can see I overwrite the placeholder with "Test User", and it works like a charm.I need to add an image (as a placeholder) to this pptx-file. When I do that (and run the code again) I get a corrupted pptx-file?
Error message: PowerPoint removed unreadable content in output.pptx. You should review this presentation to determine whether any content was unexpectedly changed or removed.
Edit: If I try the original code (which is slightly modified since I dont have Adventureworks), I get some other kind of error message:

The file has been purposely corrupted with the intent to harm your computer or your data. Be cautious when opening a file from an unknown source.
PowerPoint can attempt to recover data from the file, but some presentation data, such as shapes, text,and formatting, may be lost.

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?
I 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:
[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 trying to add an image overlay of a cell within a data bound gridview cell in ASP.Net (C#). The effect is designed to have a string within the image that is going to sit on top of the image that is pulled from the server.
IE: Database contains path to images. Data grid is pulling these images in based on the ID of the items in question. I need to pull the price from the database and lay it onto an image that is placed over the data bound image cell.
SQL Statement gets results.
Results contains path to image for items.
Items are sometimes on sale, so a special overlay is needed.
Overlay will have a varying price overlaying it.
I tried to break it down into easy portions. I am not sure if I am over thinking things or not but I can't find a feasible way to do this. The data is converted to a table due to the data grid control in ASP.Net, and there isn't any way to determine the IDs after the table is created.
I know a little bit of vb.net but don't know all that much about the asp.net technology. I do some volunteer work for a non profit organization and what I'm trying to do is integrate an image gallery into their site, instead of using an external image service that they use now.
After some searching I found an easy to use program that automatically creates the necessary thumbnails in a table.
However I want to add some functionality; when a user clicks an image for full size I want to add the option to click a button or link, to get to the next image.
I've done a lot of searching but couldn't find how to achieve this. I guess I need to find out the current image and then somehow jump to the next image.
How to implement this. Preferably I'm looking for something that is easy to implement. I'll have a number of different albums with a different amount of images. If possible I'd like to avoid having to rename the images so that they are photo1, photo2 etc.
Currently the image gallery looks like this : [URL] ....
I'm pretty sure I will need to make some changes to the viewimage.aspx file. Currently it only contains:
Not sure if you need to know the code that does the thumbnailing + creating clickable thumbnails, but I'll post it just in case it's needed
vb Code: <script language="c#" runat="server"> void Page_Load(Object sender, EventArgs e){ // Modify these numbers for the thumbnail size you want const int maxWidth = 200; const int maxHeight = 200; ArrayList pics = new ArrayList(); string html; int imgHeight; int imgWidth; foreach(string s in Directory.GetFiles(Server.MapPath(""), "*.jpg")){ System.Drawing.Image currentImage = System.Drawing.Image.FromFile(s);

I got the code from here: [URL] ....
but the contact button doesn't work, otherwise I would have contacted the original author.
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
I have been struggling for a while now to get this code working. In my mind, it should be fine. However, I cannot get this code to pass back an image url. If I explicitly name the image URL it will show, but the code will not return (or perhaps might not properly call) the url. Here are my 2 bits of code:
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:
[Code]....
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 have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
I am trying to put a default image in an Image control in asp.net and it should show that particular image on the page when no other image is assigned or no image available in Database.
I know how to display an image in gridview from image path in database. Now, I want to display an image in an asp.net image control from image path in database. Can anyone point me to a tutorial? I haven't been able to find one that explains how to do it when I don't know what the image path will be. The images are in the root folder.
