In C#,
con.Open();
SqlDataAdapter adp3=new SqlDataAdapter("select * from table1",con);
adp3.Fill(ds);
Parent_Repeater.DataSource = ds;
Parent_Repeater.DataBind();


Bind all child Repeater in Parent Repeater item Databound,

protected void Parent_Repeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
try
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{

Label lbl_userid = (Label)e.Item.FindControl("Label27");
id = int.Parse(lbl_userid.Text);

Repeater Chi_Repeat = (Repeater)e.Item.FindControl("Child_Repeater");
con.Open();
dataset ds1;
SqlDataAdapter adp1=new SqlDataAdapter("select * from table2",con);
adp1.Fill(ds1);
Chi_Repeat.DataSource = ds1;
Chi_Repeat.DataBind();nd();
}

}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
