Dropdown list in ASP.NET - How to get value selected

am sure this must be very simple, but unforunately I can't figure it out.
I have the following code which populates the dropdown lists from the database. This works fine. Now, when the user selects a particular employee name from the list, I want to get the Employee Id of the selected employee. i.e. I need to get the "Eid" value. I can do this if the EId is loaded in the dropdown list, but in this case only the employee name is displayed. Please let me know howI can get the Eid value even though it is not loaded in the dropdown list.
I would really appreciate your help

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?

Populating Dropdown List using FK


Hi Folks,

2 Questions. I am trying out Data Entities in VWD 2010 Express. I have a parent (Customers) and child (Orders) table. Customers table has FirstName, LastName and Email columns.

Q1. When I view/edit/insert an Order, it shows the customer's first name in dropdown list whereas I want the full name. How can this be done?

Q2. How can I change the default behavior of PK/FK relationship so that customer's Email is displayed instead of Name?

Any help will be much appreciated.
