The examples in this article describe the use of repeater controls in asp.net. Share to everyone for your reference. The implementation methods are as follows:

Repeater binding Data:

Copy Code code as follows:

protected void Page_Load (object sender, EventArgs e)
{
if (! IsPostBack)
Bindstudent ();
}

private void Bindstudent ()
{
String str = configurationmanager.connectionstrings["STUCNN"]. ConnectionString;
using (SqlConnection sqlcnn = new SqlConnection (str))
{
using (SqlDataAdapter da = new SqlDataAdapter ("SELECT * from Student", SQLCNN))
{
DataSet ds = new DataSet ();
Da. Fill (DS);
This. Repeater1.datasource = ds;
This. Repeater1.databind ();
}
}
}

Delete data:

Copy Code code as follows:

protected void Repeater1_itemcommand (object source, RepeaterCommandEventArgs e)
{
if (E.commandname = "Delete")
{
String str = configurationmanager.connectionstrings["STUCNN"]. ConnectionString;
using (SqlConnection sqlcnn = new SqlConnection (str))
{
using (SqlCommand SQLCMM = Sqlcnn.createcommand ())
{
Sqlcnn.open ();
Sqlcmm.commandtext = "Delete from student where sid="
+ e.commandargument.tostring ();
Sqlcmm.executenonquery ();
}
}
This. Bindstudent ();
}
else if (e.commandname = "Edit")
{
Server.Transfer ("edit.aspx?sid=" + e.commandargument.tostring ());
}
}

Front desk:
