If your dataset is too large, it might kill the speed of app. Why don't you just bind the gridview instead of looping through ..

Filling datatable is costly, usually when you loop through high volume data, application will become slower. This will happen with datatable too. If you need forward only movement, better use DataReader. They are faster.

You can probably reply to the previous thread that you have made. Plus, there are some replies for your questions. You should reply those questions without posting new thread..

If you want to show the footer of GridView in ASP.NET, you need to check "Show Footer".

Hello everybody,
I am getting an error: The name 'DataList1' does not exist in the current context.
DataList1 is a data list the code is in two pages:
Have no idea what the problem is. Any assistance is appreciated.
groups.aspx, and groups.aspx.cs
groups.aspx:
I remobed the open tags so that the code can be seen.
asp:DataList ID="DataList1" runat="server" DataSourceID="ChalkDL">
ItemTemplate>
asp:TextBox ID="postComment" runat="server">
asp:Button runat="server" OnClick="postBtn_Click" ID="postBtn" Text="Post!" />
/ItemTemplate>
/asp:DataList>
groups.aspx.cs
protected void postBtn_Click(object sender, EventArgs e)
{
SqlDataSource PostDS = new SqlDataSource();
System.Web.UI.WebControls.TextBox PostText = (System.Web.UI.WebControls.TextBox)DataList1.FindControl("postComment");
PostDS.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
PostDS.InsertCommandType = SqlDataSourceCommandType.Text;
PostDS.InsertCommand = "INSERT INTO GroupChalkboard (Text, GroupID, UserID, CreatedDate) VALUES (@Text, @GroupID, @UserID, @CreatedDate)";
PostDS.InsertParameters.Add("Text", PostText.Text);
PostDS.InsertParameters.Add("GroupID", pid.ToString());
PostDS.InsertParameters.Add("UserID", Session["UserID"].ToString());
PostDS.InsertParameters.Add("CreatedDate", DateTime.Now.ToString());
PostDS.Insert();
}

This line should be
TextBox PostText=(TextBox)DataList1.Items[IndexHere].FindControl("PostComment");

Can you get DataList1 control in codebehind side?
If no, It should be inherit problem of the page.
Check page directory of groups.aspx and class name of groups.aspx.cs.

I can't get the DataList in code behind that's the problem. The weird thing DataList1 does show up in the list and I can choose Items property and find control property. But when I run it, it says DataList1 does not exist in the current context.
How to resolve it ?
That's aspx:
%@ Page Language="C#" AutoEventWireup="true" CodeFile="groups.aspx.cs" Inherits="groups" %>
that's aspx.cs
public partial class groups : System.Web.UI.Page
{
Also
In this code: TextBox PostText=(TextBox)DataList1.Items[IndexHere].FindControl("PostComment");
what's Items[IndexHere] - what index is that. Should I count the number of items in the ItemTemplate?

Did you get runtime error or compile time error?

Yes.you have to do looping through datalist items.
