Question

Every time I run the following code, it keeps on saying “Input string was not in a correct format”. I have tried it two different ways, but it is still failing. How can I fix this problem?

protected void CEButton_Click(object sender, EventArgs e)
{
    Session["CE"] = CEDropDownList.Text;
}

If CEDropDownList is a Dropdown contol type, you will be looking for CEDropDownList.SelectedItem.Text

Say your drop down list looks like this:

<asp:DropDownList ID="CEDropDownList" runat="server">
      <asp:ListItem Value="foo">Bar</asp:ListItem>
</asp:DropDownList>

To get foo, you would use CEDropDownList.SelectedItem.Text

To get Bar you would use CEDropDownList.SelectedItem.Value
