I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.
i have drop down list bound in database and i want to make the first item in drop down list is <--select-->

View 6 RepliesI'm trying to bind the contents of a node of XML to a Drop Down List without much success. Initially, the whole XML document is bound to a repeater - this works perfectly, but now I need to display a drop down list based on the children in the "" node, but I get Data at the root level is invalid. Line 1, position 1 error message on the DataBind() method on the dropDownList. The code snippet I'm using is:

I have a DropDownList in a DetailsView, which binds a user's 'AllocatedUser' to a user in the Users table. Occasionally, we'll have some mishaps in the database where the user allocated isn't in the users table, which the DropDownList is filled with. In this case the site crashes and we get a 'SelectedValue does not exist in the list of items error'.What I want to do is catch any binding errors like that, and just set the DropDownList index to 0. I've tried something like this:
OnDataBinding='DoesExist("AllocatedUser",<%#Bind("AllocatedUser")%>)'
but it doesn't like the syntax of that.

I have 2 dropdown lists on a WebForm. One of them is populated in the page's Page_Load event. This oneworks fine with the following code.
[Code]....
Then, after a value is selected from this list and a date is selected from a DateTime picker, then I click a button which is supposed to populate the 2nd dropdownlist. In the debugger in the button's click event I can see that the dataset is being populated with data, but then the list is never populated after the DataBind() method is run. Here is code from the button's click event.

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()
