Try this,

XML

<asp:DropDownList ID="ddlStatus" runat="server">
    <asp:ListItem Text="Active" Value="1"></asp:ListItem>
    <asp:ListItem Text="De-Active" Value="0"></asp:ListItem>
    </asp:DropDownList>

if(ddlStatus.SelectedValue=="1") // For Active Status
            // Do Your Code
        else if(ddlStatus.SelectedValue=="0") // For De-Active Status
             // Do Your Code

I recommend an enumeration. Something as simple as the following may be enough:

public enum myStatus
{
  Inactive = 0 
,
  Active = 1
}

Then pass in the numeric value. You're not storing the true/false as strings, right? Right?

My article here[^] may give some more ideas.

When you have your drop down list, you could convert the selected status to a Boolean value before saving it to your database.

eg:

VB

if ddlStatus = ACTIVE then
  blnStatus = true
else
  blnStatus = false
end if

Another idea would be to have a StatusID column in your table that links back to your Status table (rather than true/false) - that was if you decide to add a new Status (say Pending, On Hold or whatever), you can simply add a new value to your Status table to display in your status dropdown list.
