Build Images Links Dynamically
Apr 6, 2010
I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code):
DynamicString = FunctionThatCreatesDynamicString()
' DynamicString = "[URL]
If ImageExists(DyanmicString) = StatusCode.200 Then
' Embed link in ASP.NET page
Else
' Embed not found image in ASP.NET page
End If
My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML.

We recently added a URL rewrite rule for a domain to run off of a share(actual name) directory. Well the domain share.site.com references the actual virtual for www.site.com/share as far as the url rewrite goes, because the menu and images must come from www.site.com/images and such. We were fine by adding in a base tag of <base href="www.site.com" />, but we started adding in modal popup and update panels then a bunch of javascript errors started bombarding the site. Is there a reason why the URL Rewrite doesn't use the virtual directory when the URL rewrite happens? I thought they fixed this.

I would like LinkText to display as a link. And when you click it takes the value from LinkURL and directs you to another page.
This is the code:
<asp:GridView id="GridView1" runat="server"></asp:GridView>
And this is the code-behind:
connection.Open()
Dim reader As SqlDataReader = cmd.ExecuteReader() [code]....

I currently have an asp.net page which a loggd in user goes to and theres a bunch of dynamically generated links to zip files that he or she owns and can downloads.Currently they click download and I have no way of knowing if it completes succesfully etc so can't log it. I do log the attempt.Is there are good download manager or solution I can use so they will have progress bars on the site, they can queue multiple ones up and most importantly I can track failed and successful downloads.

I recently stumbled upon this thread over at StackOverflow regarding the dynamic construction of a Master Page menu based on what roles a user is a part of. The original poster proposed a solution to his own problem, but rightfully noted that it was kludgey in that it didn't scale, but also that it violated the Separation of Concerns (SoC) model of MVC.

I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?

I have an Employee model that has a Name and Company
I want to be able to build multiple Employees in one CREATE view. I figured I need to create an IList<Employee> and do something like:
<%= Html.TextBoxFor(m => m[0].Name) %>
<%= Html.TextBoxFor(m => m[0].Company) %>
<%= Html.TextBoxFor(m => m[1].Name) %>
<%= Html.TextBoxFor(m => m[1].Company) %>
If a user clicks on "Add another employee", I want the view to make another form for the new employee:
<%= Html.TextBoxFor(m => m[3].Name) %>
<%= Html.TextBoxFor(m => m[3].Company) %>
And continue to add form items (and increment the array index if they click on it again).
Keep in mind that I need to build the form and the list dynamically in the create view. I don't already have a populated list of Employees.

I have SQLDataSource for my gridview. By default it works fine but i need to determine a few things before calling my procedure. By this i mean i need to determine a few things about the fields completed and set a flag to determine where the procedure will look.
I found a few examples online on passing parameters in code behind, but cant seem to get them to work. Here is what i tried and cant get results back. When i execute the procedure on the SQL side with the same parameter values, it works, so i know its returning results, so means my values are not being sent or im doing something really wrong. I have some of the lines commented out so the page can load and display for now.. but i need to get it working with custom parameters and flags.
Here is my SQLDataSource:

I am trying to build a repeater dynamically through the code behind. I found this code on the microsoft site:
Protected Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Repeater1.HeaderTemplate = New MyTemplate(ListItemType.Header)
Repeater1.ItemTemplate = New MyTemplate(ListItemType.Item)
Repeater1.AlternatingItemTemplate = _
New MyTemplate(ListItemType.AlternatingItem)
Repeater1.FooterTemplate = New MyTemplate(ListItemType.Footer)
Repeater1.DataSource = New String() {"one", "two", "three", "four"}
[Code]....
So this code works without throwing any exceptions, but what I would like to do is accessing the DataSource inside of Sub InstantiateIn(). I know you can access the DataSource in the front end using DataBinder.Eval and Container.DataItem, but is there a way to access the data during the InstantiateIn() Sub?
Or if there is another way to do this i'm up for trying that as well. Essentially I am trying to avoid writing asp.net code, instead I would rather write everything in vb (code-behind)

I have a .NET 1 web app that is using a Oracle database, the web app has a page of table names that allows the users to select, there are 101 tables listed on the page. When the user clicks on a table name, it takes them to a page that shows user friendly column headers, the table data, etc. Is there a way to use one GridView to do this and show the user friendly column headers instead of creating 101 pages or 101 user controls and show that control based on the table passed into the page?
for example: the user clicks table 22, I want my gridview to look like this
Buyer's Name State City Zip Code Phone Number
if they click table 55 I want them to see this
Product Wholesale Price MSRP Sale Price On Sale (check box)
instead of showing the users
BuyersFullName BuyersState BuyersCity BuyersZipCode PhoneNumber, etc
and so I, I would like to use 1 gridview on one page if possible and build the grid on the "fly", We have the user friendly column headers in a table.
So my questions are:
is this possible, if so, what is the best approach in doing this
from a scalabilty level and maintenance level, would the 1 gridview be worth for all 101 (and growing tables), or would building a seperate user control for each table be better?

I have a dialogue window that contains an Accordion Control that is dynamically built. The only thing that appears on my source page is the opening and closing tags for the control. The panes and the controls that appear on the panes are all added dynamically based on records in a database.
Now here is my situation, if a certian action is performed on one of the controls then I want to save that controls data and make it no longer available for use, this was easily accomplished by having the control hide itself. An issue arises though when I have hidden all of the controls on a certain pane, the header for the pane still exists and this is not the desired result.
What I would like is to be able to dynamically remove the entire contents of the control and then re-build it. Due to the timing of the events in the page post back sequence, a simple call to the method that builds the control will not work and if an explanation is required I will provide one. Also, looping through all of the panes and the controls on each pane will not work since after the first pass through the loop the panes collection is mutated, the enum table for the control is no longer correct since the initial pane has been removed, as a result the for loop throws an error.
Can any one come up with a way that I can clear out the control, keeping only the basic empty structure, and re-build it all in a single post to the server?

I'm using a lovely jQuery plugin to load static images into a thumbnail viewer - the locations are hard coded which doesn't serve us any use other than for a demo.
I've managed to pull the images from our server into a unique folder but I've no idea how to load the images dynamically to the plug in. This is the format for the images in the plug in.
[Code]....
The documentation says I can use a JSON array too:
[Code]....
But I don't know how to make this "dynamic". I have the filenames and folder location in C# in my code behind - no idea how to pass this to the jQuery plugin. I can collect the file names and pass to a new ASP page (ie no need to load from the current page).

This is something I just couldn't figure out how to do in ASP.NET:
I have a database of photographs, with upload/management and all that.
What I want to do is to dynamically change/create a css file that changes the background of a div to one of the selected images on the database. (bing.com style).
Is this possible using images stored directly on the database? (sql2008) Or maybe possible only using uploading images to a directory and saving it's path/name on database?

I'm fairly new to ASP.NET but I have developed quite a few WinForms apps in C# where I've used the System.Drawing.Bitmap namespace extensively without much issues.
Today, I decided to write some code to dynamically create some PNGs on the fly in my Page_Load event and everything seems to work fine. But I notice this scary looking warning on the microsoft documentaion site. What is up with that ??
I am unaware of any other ways to deal with images in .Net except using System.Drawing.Bitmap ...

I want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.
