I have already explain how
to create a Enum in my previous article.See My previous
article on Enum.
Now In this post I am going to explain about how to bind the enum values to the dropdown and how to read the selected item from the drop down. In Some cases we need to bind the enm data in to a dropdownlist control.in this situations it will helpful.
To Do this First create a An aspx page with the following code :
Then Add a new Class
called EnumClass and Declare the two
Enums .My Enumclass is as follows :
Output :

To Do this First create a An aspx page with the following code :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:DropDownList ID="DropDownList1"
runat="server"></asp:DropDownList>
<asp:DropDownList ID="DropDownList2"
runat="server"></asp:DropDownList>
<asp:Button ID="Button1"
runat="server"
text="Get Selected
Enum Value" OnClick="Button1_Click" />
<hr />
<asp:Label ID="Label1" runat="server"></asp:Label>
</div>
</form>
</body>
</html>
public class Enumclass
{
public Enumclass()
{
}
public enum TaskType
{
Development,
Operation,
Reporting,
Deploying,
Monitoring
}
public enum Status
{
New = 100,
Started = 300,
Partially = 35,
Completed = 400
}
}
Now add the following
code in the code behind .
protected void Page_Load(object sender, EventArgs
e)
{
if (!IsPostBack)
{
DropDownList1.DataSource = Enum.GetNames(typeof(Enumclass.TaskType));
DropDownList1.DataBind();
DropDownList2.DataSource = Enum.GetNames(typeof(Enumclass.Status));
DropDownList2.DataBind();
}
}
protected void
Button1_Click(object sender, EventArgs e)
{
Enumclass.TaskType
SelectedType = (Enumclass.TaskType)Enum.Parse(typeof(Enumclass.TaskType), DropDownList1.SelectedValue);
Label1.Text = "Task Type: SelectedText: " +
SelectedType.ToString() + " SelectedValue: " +
SelectedType.GetHashCode();
Enumclass.Status
SelectedStatus = (Enumclass.Status)Enum.Parse(typeof(Enumclass.Status), DropDownList2.SelectedValue);
Label2.Text = "Task Status: SelectedText: " +
SelectedStatus.ToString() + " SelectedValue: " +
SelectedStatus.GetHashCode();
}
Output :
