Find Label Control in DetailsView PagerTemplate

[clintonG]

Not as easy as the simple use of the FindControl method suggests when a
label control is declared within the PagerTemplate of a DetailsView control.

Anybody using Beta 2 that knows how to do this? I get close but no cigar.

Thanks for responding but still, no joy. The DetailsView control has a
BottomPagerRow property like the GridView control but the following code
raised the exception in comments...

// declarations...
<PagerTemplate>
<asp:LinkButton ID="LinkButton1" runat="server"
CommandArgument="First"
CommandName="Page"
Style="color: #232377;">&lt;&lt; First</asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server"
CommandArgument="Prev"
CommandName="Page"
Style="color: #232377;">&lt; Prev</asp:LinkButton>

<asp:Label ID="PagingLabel" runat="server">
</asp:Label>

<asp:LinkButton ID="LinkButton3" runat="server"
CommandArgument="Next"
CommandName="Page"
Style="color: #232377;">Next &gt;</asp:LinkButton>
<asp:LinkButton ID="LinkButton4" runat="server"
CommandArgument="Last"
CommandName="Page"
Style="color: #232377;">Last &gt;&gt;</asp:LinkButton>
</PagerTemplate>

// code-behind raises exception...
// Object reference not set to an instance of an object.
Label lbl = (Label)DetailsView1.BottomPagerRow.FindControl("PagingLabel");
lbl.Text = "PagingLabel Found";

Interesting to note that Intellisense 'sees' lbl identifying the object as
(local variable) Label lbl and also allows the Text property to be picked.

Hi,
You can find the control placed in pagerTemplate.
You have to do following thing in your code:
DropDownList drp =(DropDownList)
GridView1.BottomPagerRow.FindControl("DropDownList1");

Through this you can get controls placed in Pager Template.


ASP.net Control Code:

<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="First.ascx.cs" Inherits="First" Debug="true" %>
<asp:GridView ID="GridView1" runat="server"
DataSourceID="SqlDataSource1" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="au_id">
<PagerTemplate >
<aspropDownList ID="DropDownList1" runat="server">
</aspropDownList>
</PagerTemplate>
<Columns>
<asp:BoundField DataField="au_id" HeaderText="au_id"
ReadOnly="True" SortExpression="au_id" />
<asp:BoundField DataField="au_lname" HeaderText="au_lname"
SortExpression="au_lname" />
<asp:BoundField DataField="au_fname" HeaderText="au_fname"
SortExpression="au_fname" />
<asp:BoundField DataField="address" HeaderText="address"
SortExpression="address" />
<asp:BoundField DataField="city" HeaderText="city"
SortExpression="city" />
<asp:BoundField DataField="state" HeaderText="state"
SortExpression="state" />
<asp:BoundField DataField="zip" HeaderText="zip"
SortExpression="zip" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>"
ProviderName="<%$ ConnectionStrings:ConnectionString2.ProviderName
%>" SelectCommand="SELECT [au_id], [au_lname], [au_fname], [address],
[city], [state], [zip] FROM [authors]">
</asp:SqlDataSource>

ASP.net Code Behind:

DropDownList drp =(DropDownList)
GridView1.BottomPagerRow.FindControl("DropDownList1");
for (int i = 1; i < 10; i++)
{
drp.Items.Add(new ListItem(i.ToString(),i.ToString()));
}
drp.DataBind();




I hope this solves your problem.
