Forms Data Controls :: Binding A Repeater To A List Of Objects That Have Child Objects?
Nov 17, 2010have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>

Forms Data Controls :: Gridview With List Of Objects?
Feb 5, 2010I have a List of Customers. Now I want to display these customers in a gridview and that is easy. I just set the datasource and use the databind method of the gridview. (I use template fields). But now I want to display FirstName and LastName of the customer as one column.I am aware of how to use the rowdatabound event to manipulate the gridviewrow's controls, but I am not sure how to gain access to the customer object within this method.So here is some code which of course not works.
protected void grdVirtualCustomers_RowDataBound(object sender, GridViewRowEventArgs e)
{
System.Web.UI.WebControls.GridViewRow row = e.Row;
((Label) row.FindControl("lblName").).Text=Customer.FirstName + " " Customer.LastName;
}
Forms Data Controls :: Display List Of Objects In GridView?
Feb 16, 2010I'm creating in my code a list of object which must be displayed later in a table.
In Winforms I'd simply bind the DataGridView to the list, and everything is fine.
However, when I try to set the GridView's data source to the list, nothing happens, and I can't find a way to do this with any of the procided data sources(Such as ObjectDataSource, etc.).
Forms Data Controls :: Gridview Two Way Binding And Custom Objects?
Nov 24, 2010I have been reading alot about this and for some reason I am just not able to grasp the concept. Hopefully someone here can enlighten me.As an example situation I have a collection of strongly typed User objects that represent a database table, and some properties that represent its columns: UserID(PK), Username,FirstName,LastName, etc..Here are some of my requirements/goals:1. Users/Objects needs to be bound to the gridview programatically.2. I do not want to update the database right away, I only want the underlying collection to be updated. I would like to call the database update method myself when I am ready.
3. I do not want the primary key stored on the client side.Summary:So I bind a List<Users> to a gridview with the appropriate bound fields set up, I exlude bound fields such as primary key because I don't want it being changed/hacked by the client side. When I edit and update a row it is saved back to the collection of objects. I will iterate through the objects manually at a later time and commit them to database.
Questions:1. Can I cast a gridview row directly back to my object, in the RowUpdating or RowUpdated events? I am assuming I can't... So....2. How can I reference back my original collection if the gridview does not contain a primary key?3. Where do I store my collection, should it be in Session or should I recreate it on each postback?Sorry if any of this is confusing, let me know if you need clarification.

View 1 RepliesDataSource Controls :: Accessing Array Objects In Sql Statement?
Jun 6, 2010I have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.
What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..

DataSource Controls :: Obtaining Collation Info From Objects?
Jan 21, 2010For some reason, some of the fields in our database use a different collation than the default. There doesn't seem to be a pattern as to which fields use the different collations, so I'd like to run a query to find which fields use this collation and change them to the default. Does anyone know how to do this?

DataSource Controls :: Static Variables Vs Linq2sql DataClassesDataContext Objects
May 6, 2010im developing a silverlight project using silverlight 3, vs2008 and linq2sql. when projects starts, im storing all the data from database into some static list variables. so when ever i need data, im reading it from those static list variables. all i want to know is, is it good to store data in static list variables and use it when ever necessary or is it good to get data directly from DataClassesDataContext object like db.mytable. which is the rite and fastest way or retrieving data. i mean which will use less connections to database?

Feb 24, 2010I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?

C# - How To Bind A DataTable With Complex Data Objects To A GridView
Jan 31, 2011My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.

When Generate Against This Db Get All Kinds Of Errors Because Subsonic Is Expecting That Field To Be A Varchar?
Feb 14, 2011I'm working against a database that wasn't designed by me and in all the tables there is a CreatedBy field that is an int. Now when I generate against this db i get all kinds of errors because subsonic is expecting that field to be a varchar.
I don't particularly want to go and rename the field in all of these tables so I was hoping there was a way to "alter" or change the internal convention (without getting into the source) in subsonic.
Has anyone been able/done this in subsonic 3.0.4??
EDIT: I'm using the active record model in subsonic 3
