Forms Data Controls :: GridView Doesn't Show Picture In Row

Aug 24, 2010

I do a gridview code that when displaying the information that come from the database is not showing any error at all, but is not displaying the right picture. The problem, I think, is that the (Eval("....") is not reading the values that are coming from the DataKeysNames. Due to this the right pictures are not displayed. But in another column, just for testing purposes I was able to display the values from DataKeysNames with the Eval. So I do not know what is going on and to make worse browser is not giving me any error. So, this is the line that is not processing, reading or executing well:

ImageUrl='<%# IIF( (Eval("TUDTIWasItemUpgraded")) = "Yes",&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string.Format("~/Images/ItemUpgradedTo.gif"),&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string.Format("~/Images/ItemNoUpgradedYet.gif")&nbsp;&nbsp;&nbsp; )&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; %>'

And this is the complete code for the GridView

Forms Data Controls :: Tumbnail Link Picture In GridView?

Jul 15, 2010

I am using VWD 2005 Express and Visual Basic.When my SQLDataSource feed my GridView, it does get the AutoNumber (GUID) of each record as well, to use it as a name for stored pictures. Pictures are not in the database but in a folder. Since I have several pictures, I do manipulate this ID with code and I add to it, pic1, pic2, etc and that is the final name for each picture, for each particular record. Example: The ID for one record in the database may be, 45623sdgd. If I have four pictures for this particular database record, the names will be, 45623sdgdPic1, 45623sdgdPic2, 45623sdgdPic3, and so on after Pic is added. After this I save these pictures in a folder.

Now, when I display the record information with a GridView, I get the AutoNumber of each record using: DataKeyNames="AutoNumber". I want to display a thumbnail picture link as well. But I really do not have many options in term of what control to use for the thumbnail inside the GridView. I tried the following controls unsuscesfully. HyperLinkField, can not add a picture to this one. ImageField, can not add a link to this one. ButtonField does not have a DataImageUrlField="AutoNumber" to get the AutoNumber. So since to be that my only opton is the asp:TemplateField. But it is giving me error with the coding. This is my coding,

Code:

<asp:GridView
ID="PublicClassifiedsSamplesGridView"

Jul 19, 2010

I do have the following code for for a GridViewd that display pictures that are stored in a file. I am using AutoNumber(GUID) from the database to name the pictures before I stored them to the file.

Forms Data Controls :: DataGrid Doesn't Show Data After Postback?

Jan 21, 2010

I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.

In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.

It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.

Web Forms :: Upload Picture From Desktop Code Seems Correct But Doesn't Work?

Feb 25, 2010

I am trying to do some code where a user will be able to upload a .JPG picture from the users computer. I have put the controls and also written the C# code wich in my eyes seems to be correct. What happens in the code is that the uploaded picture will replace the existing "TopHeader.JPG" picture.

However when I run the code after I have choosen a .JPG picture from the desktop on my computer. Nothing happens except of a postback of the page.

I wonder what I can be missing out in order to make this work. (I attach both the HTML code and the C# code, I will be happy to know what I could be missing out)
