im trying to build a gallery using C#.
Ii've made a Listview showing photos from database as thumbnails in a "kind of a film strip", including a pager.What i need is that when i click on a thumbnail inside the ListView, to show the large photo in a image control outside the listview. this should work using the selectedIndexChanged event,
Is it possible to display thumbnails for the photos when uploading them to the server? Say, when user selects a photo on the local drive, a thumbnail is displayed on the page for preview and when user clicks on the "Upload" button, the photo will be sent to server.
View 2 RepliesI want to make a website which showing thumbnail images be taken from local folder,say,'thumbnails' inside the root folder like listview items.Below each thumbnails,the name of the file would be displayed with check boxes for selecting any thumbnail images.Clicking on any thumbnails will redirect to another page where the thumbnails and the original image(with the same name in some other local folder say 'Original') would be displayed.

I have a Listview that is connected to an EntityDataSource. What I'm having trouble doing is showing fields of an association in the Item Template rather than just the id.
For example, what it currently shows:
Name: John Doe
Race: 3
What I wish it would show
Name: John Doe
Race: Caucasian
Some example code:
[Code]....
Obviously, I'm getting the number because Race_ID is an integer. What I'm less sure about is how to bind it or Eval it in some manner that will let me match that id to a name in the other table (which is associated). I've tried <%# Eval("Race.Name") %>' and a few other things to try to get a name rather than an ID but I always get either the id or nothing at all.
I have a listview that shows the user the details of the members who have sent friendship request. The table from which the data come has two fields namely, sender_id[id of the one who sends friendship request] and receiver_id[id of the one to whom the request is sent].
There will be two columns in the listview. The first would show the pic and the name of the user. The problem is that how am I going to show the pic and the name if the table from where the data come does not contain these info. I know that the sender_id can be used to fetch the pic and name of the sender, but how should it be done?
Earlier I would do something like <%#Eval("fieldName")%>. But in the above described scenario the field is not present in the current table but the other one.
I'm using listview with datapager.
when I'm trying to change the page if an item is in edit mode, the item with same row number in other page is opening in edit mode.
I have added a list view to my page. I can not set the BorderStyle property for the listview. The BorderStyle property does not appear in the intelli sense when in the aspx of aspx.cs file.
View 4 RepliesI have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):

I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

I know we can show image thumbnails in a gridview...but what about thumbnails of word documents and pdf files?

I am trying to display 4 photos per row
Now I am not sure how to evaluate this statement because it evalues true if I have 2 images the other two will mark up as an X
<img src="<%# DataBinder.Eval(Container.DataItem, "Column1")%>" visible="<%# (DataBinder.Eval(Container.DataItem, "Column1")!="") ? true:false %>"
This is always visible. All of them are evaluating to true.

I want to show my database records in circle. If i use grid view or data grid or datalist then records will show in table structure. I want to show dynamic records in circle not as like forum view.
View 9 RepliesI have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:

So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:

I'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).
