C# - Binding To A List <string> Using DataBinder.Eval?

Sep 3, 2010

I have the following object:

string RowName{get;set;};
int RowId{get;set;}
List<string> CellContents = new List <string>();
//Constructor..... etc.

I'm building a dynamic crosstab grid using GridView in 3.5

I wish to bind to CellContents[0] for dynamic column 1, CellContents[1] for dynamic column 2 (dynamic column 0 is the RowName field from the CrossTabDataObject) etc. I am using:

object boundValueObj = null;
Control ctrl = (Control)sender;
IDataItemContainer dataItemContainer = (IDataItemContainer)ctrl.NamingContainer;
boundValueObj = DataBinder.Eval(dataItemContainer.DataItem, strSelectedID);

This code is in the InstantiateIn function of the gridview as I'm creating drop down list templates in each cell of the crosstab.

I have code (not shown) that sets strSelectedID depending on the column being created.

When strSelectedID is equal to "RowName" for dynamic column [0] the DataBinder.Eval function works fine and sets boundValueObj as expected. The problem comes when strSelectedID is set to "CellContents[n]" where n is the Column Index.

DataBinder.Eval only works with properties and fields of objects. How do I get around this?

C# - Getting DataBinder Item's Max Value?

Mar 30, 2010

I'm working at the aspx page, and the following code is inserted in a Repeater control:

<%# ((System.Collections.Generic.List<double>)DataBinder.Eval(Container.DataItem, "BookPrices")).Max() %>

Brings up the following error: 'System.Collections.Generic.List<double>' does not contain a definition for 'Max'

List does have an method of Max(), so I'm possibly messing up my code somehow. What is my problem?
BookPrices is a list<double> object, which I'd like to print it's maximum value.

Forms Data Controls :: ADO.NET Versus SqlDataSource

Jun 29, 2010

I am developing web-app in .NET for 5 months (and enjoying it =)) and I am reading 3 books, all of them teachs at least 2 methods for acessing data: ADO.NET and SqlDataSource object.

I am used to work with ADO.NET method because I feel that even if it needs coding by hand, I can separate the SQL routines from the page and I can customize database routines better.

For now I am using DataReader mode because the application and the database is on the same server and there is only 1Gb RAM available so there is no advantage using DataSet on this moment.

Am I thinking this right? There are some things with SqlDataSource that I don't know how to do it well...

For example:

I have a routine that inserts a record on a table then gets the ID of this record using SCOPE_IDENTITY() function of SQL Server, than it uses this ID to insert another record on another table. Because I use a one-to-many relationship on multiple tables...

How can I work this situation using SqlDataSource object, is it even possible?

Forms Data Controls :: Using Custom Text Before Eval?

Mar 4, 2011

I have a repeater that has been given a datasource from my database containing pictures. The problem is that when i create and log a user into my site i send him to a folder that has no access from others than the ones with a roles called User. When he creates his profile, he uploads a picture which is saved in the same folder "User/picture/picturename" and in the database "picture/picturename".

Now i need to pull this picture to the Default page page where users are not logged in. If i add an Image Control to the frontpage with ImageUrl='<%#Eval ("PictureThumbURL") %>' it tries to pull out the picture from the folder User which is obvious that it can't since it lacks the User/ in front.

Is it possible to get this picture by manually adding User/ to the ImageUrl='<%#Eval ("PictureThumbURL") %>' and if so, how?

Works great except I don't want the image to display if both datafields are empty. How can I add that logic into this Eval stmt?
