Forms Data Controls :: Listview Showing Photos From Database As Thumbnails ?
Mar 15, 2011
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.
I 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 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.
I 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):
[Code]....
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 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.
I 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:
[Code]....
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:
Can anyone tell me how to create an ASP photo album page WITHOUT using a database for the photos? In other words, I just want to be able to call the photos from a folder within the site... I can't get databases to work properly on my computer so I need to do it this simpler way. Can anyone let me know of a site which shows how to do this
I am having one column in each row of my radgrid in which i want to show an image. I am getting values from database saying 1,2 for that particular column and for each of these values i want to show different images for different values. For Example if i am getting 1 from database i want to show "roseImage" and for 2 i want to show "lotusimage",
I would like to know what the best method of uploading a batch of images/photos would be. Below are the steps that need to be implemented: Select Multiple images/photos from a directoryUpload original images to webserverGenerate thumbnailsUpload thumbnails to webserverAdd image and thumbnail details to a Database Does anyone know any vb.net script that will allow me to do this or will I have to code it from sratch?
My issue is that the first row of data in my db table does not seem to be output to my ListView control when I run the page. The first item in the ListView control is the 2nd row of my db table.
If I execute the stored proc listed below in SQL Server Mgmt Studio all rows are returned to the query results window.

I have a listview. Inside the EditItemTemplate of this listiview I want to show a Checkboxlist that has 5 checkboxes; S, M, L, XL, XXL. The values (checked / unchecked) of these checkboxes are dependent on a linq query. The linq query just retrieves the values from columns in a table. The columns are S, M, L, XL, XXL (same name as checkboxes for convenience) and all have datatypes bit. What I want now is to be able to databind this query result to this CheckBox list.

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).
I am using entity framework. My model has entity tblGameInfo where in navigation properties are associations called tblPlayer1 and tblPlayer2 which links to entity tblPlayer. I have listview on my page where I want to show game info with players names. I have found that in of listview I should have e.g. one of those:
[Code]....
But it does not work. I got nothing displayed in a listview. I have tried many different options but cannot find working one. Probably is some simple mistake but I am new to asp.net and cannot find it. Second problem with this is editing. In edit template there is dropdownlist with all players.
[Code]....
How do I databind it? It is not allowed to bind and change properties? It writes me that element does not exist on a list of elements.
