从转发器中的后面代码引用控件ID

Question

This week I had a problem of trying to determine what control to use to be able to display data from multiple data sources in a non-grid looking way. Thanks to this forum, I have learned that the best way will be to use a Repeater with different controls such as labels and tables inside the repeater. Not quite sure exactly how I will get it all implemented yet but the first thing I need to learn is how to change the text from the code behind of a table and a Label that I will have inside the repeater. I have read up and found that the following should work. but it doesnt.

for (int i = 0; i <= Repeater1.Items.Count - 1; i++)
            {
                Label labelCustomerID = (Label)Repeater1.Items[i].FindControl("labelCustomerID");
                labelCustomerID.Text = "from code Behind";

            }

my declarative syntax is this:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
    <ItemTemplate>
            <hr/>
            <asp:Label runat="server" ID="labelCustomerId"  />
            <div style="padding-left:150px">
                <asp:Label runat="server" ID="labelCustomerName" />
                <asp:Label runat="server" ID="labelCustomerAddress" />
                <asp:Label runat="server" ID="labelCityState" />    
            </div>
            <asp:GridView runat="server" ID="gridViewRecordData">

            </asp:GridView>
            <hr/>
        </ItemTemplate>
 </asp:Repeater>

Thanks to EdB I have gotten this far. Not still sure how I am gonna fill the gridview with one record of data but first things first... I need to be able to change a label's text. If i can get that done I am sure the rest will fall into place.

Please help me! :) dell

Try with this code :

for (int i = 0; i <= Repeater1.Items.Count - 1; i++) 
        {
            if(Repeater1.Items[i].ItemType == ListItemType.Item || Repeater1.Items[i].ItemType == ListItemType.AlternatingItem)
            {
                Label labelCustomerID = (Label)Repeater1.Items[i].FindControl("labelCustomerID"); 
                labelCustomerID.Text = "from code Behind"; 
            }

        }

我认为您在填充中继器之前就已对其进行了引用。
