Creating DataGrid's hyperlink columns with multiple parameters in the Url

The DataGrid's HyperLinkColumn column is great to have a column with an hyperlink that points to an Url with a parameter whose value is taken from the data source, but what if you need to build the target Url with more than one parameter taken from the data source? In this case you can use a template column as follows:

<TemplateColumn>
    <ItemTemplate>
       <asp:HyperLink Runat="server" NavigateUrl='<%# _
          "Details.aspx?EmployeeID=" & Container.DataItem("ID") & _
          "&EmployeeName=" & Container.DataItem("FirstName") %>' />
    </ItemTemplate>
</TemplateColumn>

Instead of doing the string concatenation yourself you can use the BuildUrlWithQueryString function, which must be declared with Public/Protected visibility in the code-behind, as follows:

<TemplateColumn>
    <ItemTemplate>
      <asp:HyperLink Runat="server" NavigateUrl='<%# _
         BuildUrlWithQueryString("Details.aspx", _
         "EmployeeID", Container.DataItem("ID"),
         "EmployeeName", Container.DataItem("FirstName")) %>' />
   </ItemTemplate>
</TemplateColumn>
