Is there any item selected in that dropdown ?

There are 2 aspects :
1. IF you want to bind then you can do something as below :

<asp:DropDownList ID="ddlState" runat="server" DataSourceID="sqlDatasource1"
DataTextField="State" AppendDataBoundItems="True"
SelectedValue='<%# Eval("State") %>' DataValueField="State">


Refer below link :

2. Intending to assign the selected value of a dropdown present in a gridview into the a label (as you are trying the solution above , i assumed you are only assigning) , you can do as below :

Label456456.Text= ((DropDownList)row.FindControl("DropDownList5")).SelectedItem.Value;

This would work. Kindly debug !!!
