How do I Bind in ASP to a SQLDataSource?
I'm trying to wrap my head around databinding using a sqldatasource. Right now I have a sqldatasource, databound fields, and template fields that I bind using: <%# Bind("ColumnName") %>. I understand databound fields, but when using the "Bind" command on a template field, how does it know the value to put there? Does it开发者_JS百科 find the ID for the row and then use the sqldatasource to get the value?
Also, how would I go about doing the same thing as "Bind" in ASP, but in the C# code behind instead?
Check the following article:
ASP.NET data binding overview
Visual C# .NET
<%@ Page language="c#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<script runat="server">
void Page_Load(Object sender, EventArgs e)
{
SqlConnection cnn = new
SqlConnection("server=(local);database=pubs;Integrated Security=SSPI");
SqlDataAdapter da = new SqlDataAdapter("select * from authors", cnn);
DataSet ds = new DataSet();
da.Fill(ds, "authors");
Repeater1.DataSource = ds.Tables["authors"];
Repeater1.DataBind();
}
</script>
<html>
<body>
<form id="WebForm2" method="post" runat="server">
<asp:Repeater id="Repeater1" runat="server">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem,"au_id") %><br>
</ItemTemplate>
</asp:Repeater>
</form>
</body>
</html>
