Here's an example.
Was there anything specific you were looking to see?

C#

protected void Page_Init(object sender, EventArgs e)
{
    DropdownList.DataSource=GetData();
    DropdownList.DataTextField="TextColumn";
    DropdownList.DataValueField="ValueColumn";
    DropdownList.DataBind();
}

    base.OnInit(e);
    DropDownList ddl= new DropDownList();

The problem I am facing is that I have a drop down list on a form and each time the data is uploaded the value in the record which feeds into the control of the drop down list is not updated on the form.

for instant I have a drop down list with 2 options "Active" and "Inactive"

1. I have stored "Inactive" for a particular person, however each time I select the person from the gridview the drop down list doesn't change to "Inactive" but "Active" comes up

</td>
<td bgcolor="#DDDDDD" class="style9">
<asp:DropDownList ID="ddl_Status" runat="server" Height="16px" TabIndex="12"
Width="183px">
<asp:ListItem>Active
<asp:ListItem>Non-Active

</td>

Pls assist
