Forms Data Controls :: How To User "City" Property Of Address Class In DataTextField
May 24, 2010
I have a class (SearchClass) in which i have Origin property which is a "Address" datatype. I want to use the "Search" class in my Search.aspx. I want to bind the City field data to a CheckBoxList, but i could not do so? If it is a straight property of Search class i could do so, but if it is a property then i could not. "I am getting error "City" is not a valid DataTextField of something like that. The point is it is not recongnised. I even tried to inherit the Address class from Search.cs class, but i just see blank data. Now i am trying to a different thing. i.e. Inherit the Address in Search.cs class and while pouplating the Search Results in to a List object i am also planning to set the data of City too, along with populating the whole Address objects and try to use it in my binding. Is there any other way to do this (i mean more efficiently)?
SearchClass.cs:-

I have a simple model and view-model:
[Code]....
The view is strongly typed on AddressViewModel, and renders html elements using the xxxFor() helper methods, e.g.:
[Code]....
The html elements' names get prefixed by Address, so the name of the text element for the city ends up "Address.City" and the select element for the state ends up "Address.StateId".
I then added validation (a'la NerdDinner) - when the Address detects there is something wrong with the City it throws an exception and the controller retrieves the violations from the Address, e.g.
[Code]....
The problem (I think) is that ValidationMessageFor() looks for an error for a property "Address.City", however the error was added using the property name "City".
How does one deal with this problem - the problem being that the property name in html ends up not the simple property name that the validation logic used?

I have a list <Department> say Company.Departments with object Manager and ManagerId, ManagerName as property of Manager. I would like to fill the dropdownlist with managers as below
ddlManager.DataSource = Company.Departments;
ddlManager.DataTextField = "ManagerName";
ddlManager.DataValueField = "ManagerId";
Is there a way to specify the property of an object in DataTextField or I need to copy a Manager list for the DataSource?

I would rather not magic string my DataTextField/Values on the dropdownlist after setting up the source as a List collection of objects.
I was thinking I could use the DataSource properties but it doesn't seem to like the couple of ways I tried.
WORKS BUT NOT IDEAL
//set the datasource to the returned List<Cart>
this.cartDdl.DataSource = CartManager.Load(WebProfile.Current.UserName);
//set the DataValueField to the Cart.ID property
this.cartDdl.DataValueField = "ID";//would rather use the obj property Cart.ID
//set the DataTextField to the Cart.Description property
this.cartDdl.DataTextField = "Description";//would rather use the obj property Cart.Description
//Bind the ddl to the datasource
this.cartDdl.DataBind();
HOW I WOULD THINK IT COULD WORK this.cartDdl.DataValueField = ((Cart)this.cartDdl.DataSourceObject).ID; this.cartDdl.DataTextField = ((Cart)this.cartDdl.DataSourceObject).Description;

the EntityA is the main object (contains the primary key), but has a navigation property called "EntityALanguages", which contains language specific properties.
now i want to bind the list to a dropdownlist and need so set DataValueField and DataTextField properties from the dropdownlist.
how can i set the DataTextField to a property of a navigation property, something like:
this.ddl.DataValueField = "GUID";
this.ddl.DataTextField = "EntityALanguages.ShortDescription";

I have a State class defined like this:
Public Class State
Public Property StateId As Integer
Public Property Name As Dictionary(Of Integer, String)
End Class
Name(x) contains the state name in different languages. I get a collection of State from the method StateManager.GetAllStates() and I want to bind this collection to a DropDownList. The problem is that I can't find how to set the DataTextField property to let's say stateList.Name(1) which is the english name of my state.
Dim stateList As StateCollection = StateManager.GetAllStates()
Me.DataSource = stateList
Me.DataValueField = "StateId"
Me.DataTextField = "Name(1).Value" <-- Problem here
Me.DataBind()

In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.

I have two tables, both contains same properties. The problem is the address spellings MAY vary between table 1 and table 2 but they are actualy same properties. In my sql statement it list out the property that has exactly the same spellling. How do I match the two tables addresses? I heard about fuzzy algorithm but how do I apply it here. I know it wont be perfect but it will be close (check my sql below) I use sql server 05.
Example
Table 1
- 123 greenwood hwy
- 123 halo street
Table 2
- 123 greenwood highway
- 123 halo street
SELECT table1.address,table2.street_address
FROM table1 INNER JOIN
able2 ON table1.address = table2.street_address
My Output returns only one property that has same exact address spellings
- 123 halo street | 123 halo street

I tried to add a custom property to the data model:
public partial class Department
{
public string ExtensionIdName
{
get
{
return Extension.ExtensionName;
}
set
{
}
}
}
It seems that it works, but when I bind the data to a ListView it shows all the properties except the property I added manualy (ExtensionIdName).
