first - i select values from my cascading drop down list then enter values for two textbox (dates). then when i hit the button to populate my grid nothing is return back.

I have a textbox for City field and a drop down list box for office location which has to be filled up based on the City value.
How to populate the values of drop down list box from an xml file keeping the above consideration.
I am doing this in a asp.net user control and C# code behind
In future i need not change the code every time. Its only the xml file i change and the corresponding city related office locations get listed in the drop down list box.

I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
I've currently got a form with two dropdown boxes on, and an XML file sitting on the site.
My two drop down boxes are Location and Date and what i'm trying to do it get the Location box to filter the XML and put the dates in the Date dropdown box.
I'm using C#.
Unfortunatly, its not working.
My code is:

and my XML is like this:

why my dropdown boxes are not being populated?
I need the simple task of populating a form from a dropdown if customer IDs.
The problem is I'm new to MVC and I no longer have events, so I'm not sure how my dropdownlist can have a postback event that does one thing, and my update button can have a postback event to do another thing.
Example, this only goes to the post action, so how does it know to load the customer or do an update:

I am running into some additional difficulties with dropdown lists, and I'm hoping you can correct my thinking.
I have a table populated with items; ITEM_ID, ITEM_NAME, ITEM_COST.
Here is my code:
[Code]....
With this code I get this error: DataBinding: 'ITEM' does not contain a property with the name '2'.
If I remove the assignment of DataSource to c1, the dropdown generates this error: 'DropDownList3' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
How should I code this so that the user is presented with a list of ITEM_NAMES, and that the ITEM_ID is stored in the value field so I can use it when the selection event is fired? I know I could databind the source directly to the dropdown list, but I am trying to understand the behind the scenes working of a dropdown list object.
I am populating a page with controls reading properties of a class using reflection. If the property type is 'String' I will add a text-box. If the property type is enum I am adding a dropdownlist. Now I have to populate the dropdown options with enums. How can this be done?
Both the enum definition class(Assignment) and the class(classOne) using which I am populating the page with controls are in the same Namespace(MySolution.Data). While looping through classOne properties when the property name is 'SkillLevel' I will have to go to assignment class get the members of enum SkillLevelEnum and populate the dropdown.
Same needs to be done for other dropdowns also.
My Code:
namespace MySolution.Data
{
public class classOne : MyAdapter
{
private string _Model;

I have been searching the forum for how to populate a dropdown without "spaces" or "-" but I can not find exactly what I am looking for.Actually the data input by the user contains specaial character and using datasource the dropdown is being populated with the original data but every user has different style to insert data so I want to populate dropdown(within forview) without spaces or dashes, hashes. By making this change I may be able to populate dropdown in an asc or desc order.I know it can be handle from database but I want to do it with some coding technique in vb.net or asp.net.

View 2 RepliesI'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
