You should use style(css) to hide that element.So that it can be rendered in code behind file where you want to find the value of Hidden field. Just use

  <asp:Label ID="hf1" runat="server"  style="display:none"><%# Eval("DeptId")%></asp:Label>

instead of 

  <asp:Label ID="hf1" runat="server" Visible="false"><%# Eval("DeptId")%></asp:Label>

then everything will work fine for you. Thanks Gourav

With the Label you can also get the controls in EditCommand event as below:

protected void dlData_EditCommand(object source, DataListCommandEventArgs e)
{
    Label hf1 = (Label)e.Item.FindControl("hf1");//Any control you can find here
}

Also if you need to filter data item only in that case just put a condition:

protected void dlData_EditCommand(object source, DataListCommandEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item)
    {
        Label hf1 = (Label)e.Item.FindControl("hf1");
    }
}

Use HiddenField instead of Label with Visible="false". You may obtain the reference of control in DataList via FindControl(id) method.

Markup:

 <asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("DeptId") %>' />

Code in EditCommand:

HiddenField h=e.Item.FindControl("HiddenField1") as HiddenField;

Visible="False" will not render any content to the page. Use a <asp:hidden> control instead:

 <asp:hidden ID="hf1" runat="server" Text='<%# Eval("DeptId")%>' />
