Re: how to find control from header template of a datalist?

Instead of  finding  the control in the header template of datalist in page load event .you can put the code which you want to execute after finding the control inside a function and then call that function from the header template.Below is a example:->
<asp:DataList ID="dtlisFirstSubCategories" runat="server">
        <HeaderTemplate>
            <%#GetParentCategoryName() %>
        </HeaderTemplate>
        <ItemTemplate>
            <asp:LinkButton ID="lbtnSubCategory" runat="server" CommandArgument='<%#Eval("ProductCategoryID")%>'
                Text='<%#Eval("Name")%>'  PostBackUrl='<%#"~/Category.aspx?parentCategoryID="+Eval("ProductCategoryID") %>'
                OnClick="lbtnSubCategory_Click"> </asp:LinkButton>
        </ItemTemplate>
    </asp:DataList>


now in cs file you can put code as follows:->
public string GetParentCategoryName()
    {
String parentCategoryName="";    
  //add logic here to get the category name

return parentCategoryName;
    }
