Get control instance in asp.net dynamic data - asp.net

Question

I am creating a web application using Asp.net dynamic data. I am using GridView to show data from the database.
In the grid view I am having following code for columns
<Columns>
<asp:DynamicField DataField="UserId" UIHint="Label" />
<asp:DynamicField DataField="Address" UIHint="Address"/>
<asp:DynamicField DataField="CreatedDate" UIHint="Label" />
</Columns>
But, before displaying I want to do some processing in C# code for each row. In normal ASP.net grid view we can handle OnRowDataBound method, and using FindControl("controlid") we can get the control instance, but in case of dynamic data, I am not getting any id attribute for columns, so I am not able to get the control instance to show updated data in that control depending on some conditions.
Thanks,

Try using a TemplateField instead of DynamicField: http://msdn.microsoft.com/en-us/library/bb288032.aspx
An example of how to use:
<asp:Templatefield headertext="Author Name">
<Itemtemplate>
<asp:label id="FirstNameLabel"
Text= '<%# Eval("au_fname") %>'
runat="server"/>
<asp:label id="LastNameLabel"
Text= '<%# Eval("au_lname") %>'
runat="server"/>
</Itemtemplate>
</asp:Templatefield>
Here are the options available to you:
<asp:TemplateField
AccessibleHeaderText="string"
ConvertEmptyStringToNull="True|False"
FooterText="string"
HeaderImageUrl="uri"
HeaderText="string"
InsertVisible="True|False"
ShowHeader="True|False"
SortExpression="string"
Visible="True|False">
<ControlStyle />
<FooterStyle />
<HeaderStyle />
<ItemStyle />
<AlternatingItemTemplate>
<!-- child controls -->
</AlternatingItemTemplate>
<EditItemTemplate>
<!-- child controls -->
</EditItemTemplate>
<FooterTemplate>
<!-- child controls -->
</FooterTemplate>
<HeaderTemplate>
<!-- child controls -->
</HeaderTemplate>
<InsertItemTemplate>
<!-- child controls -->
</InsertItemTemplate>
<ItemTemplate>
<!-- child controls -->
</ItemTemplate>
</asp:TemplateField>
