C# - Check If A Drop Down List Contains A Value?
Jan 5, 2010
When the user navigates to a new page, this ddl's selected index is determined by a cookie, but if the ddl doesn't contain that cookie's value, then I'd like it to be set the 0. What method would I use for the ddl? Is a loop the best way, or is there a simply if statement I can perform?
This is what I've attempted, but it doesn't return a bool.
if ( !ddlCustomerNumber.Items.FindByText( GetCustomerNumberCookie().ToString() ) )
ddlCustomerNumber.SelectedIndex = 0;

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.

I have a page that has two drop down lists on it and a button. All controls sit in an update panel. The first drop down list (ddl1) contains a lot of values which caused a huge viewstate so I disabled viewstate on it. In the page oninit event I populate the drop down list every time the page is posted back. This all seems to work fine, it shows all the values and I can access the selected value in my event handler.
ddl1 has the autopostback attribute set to true so when its value changes the second drop down list (ddl2) is populated with some values that depend on the selection in ddl1. This also works fine, the values in ddl2 change when I select a value in ddl1.
ddl2 does not have viewstate disabled. The button that sits under my two drop down lists is disabled by default and becomes enabled when the value of ddl2 is changed to anything except string.empty. This is where I run into problems. ddl2 does an autopostback too but it seems to lose the selected index/value. When I'm in my code to check whether to enable or disable the button the selected index is always 0 and the selected value is string.Empty.
If I enable viewstate on ddl1 this all works fine. Could anyone point me to what I'm doing wrong?
Here is the code executed by the ddl2 postback:

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?
