如何在Repeater控件中实现像GridView控件一样的编辑、更新、删除功能？下面有个不错的示例，感兴趣的朋友可以参考下，希望对大家有所帮助
代码如下:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
string strSQL = "SELECT * FROM [User]";
OleDbConnection objConnection = new OleDbConnection(GetStrConnection());
objConnection.Open();
OleDbCommand objCommand = new OleDbCommand(strSQL, objConnection);
OleDbDataReader reader = objCommand.ExecuteReader(CommandBehavior.CloseConnection);
rptUser.DataSource = reader;
rptUser.DataBind();
}
protected void rptUser_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
System.Data.Common.DbDataRecord record = (System.Data.Common.DbDataRecord)e.Item.DataItem;
int userId = int.Parse(record["UserId"].ToString());
if (userId != id)
{
((Panel)e.Item.FindControl("plItem")).Visible = true;
((Panel)e.Item.FindControl("plEdit")).Visible = false;
}
else
{
((Panel)e.Item.FindControl("plItem")).Visible = false;
((Panel)e.Item.FindControl("plEdit")).Visible = true;
}
}
}
protected void rptUser_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
id = int.Parse(e.CommandArgument.ToString());
}
else if (e.CommandName == "Cancel")
{
id = -1;
}
else if (e.CommandName == "Update")
{
string name = ((TextBox)this.rptUser.Items[e.Item.ItemIndex].FindControl("txtName")).Text.Trim();
string email = ((TextBox)this.rptUser.Items[e.Item.ItemIndex].FindControl("txtEmail")).Text.Trim();
string qq = ((TextBox)this.rptUser.Items[e.Item.ItemIndex].FindControl("txtQQ")).Text.Trim();
string strSQL = "UPDATE [User] SET Name=@Name,Email=@Email,QQ=@QQ WHERE UserId=@UserId";
OleDbConnection objConnection = new OleDbConnection(GetStrConnection());
OleDbCommand objCommand = new OleDbCommand(strSQL, objConnection);
objCommand.Parameters.Add("@Name", OleDbType.VarWChar);
objCommand.Parameters["@Name"].Value = name;
objCommand.Parameters.Add("@Email", OleDbType.VarWChar);
objCommand.Parameters["@Email"].Value = email;
objCommand.Parameters.Add("@QQ", OleDbType.VarWChar);
objCommand.Parameters["@QQ"].Value = qq;
objCommand.Parameters.Add("@UserId", OleDbType.Integer);
objCommand.Parameters["@UserId"].Value = int.Parse(e.CommandArgument.ToString());
objConnection.Open();
objCommand.ExecuteNonQuery();
objConnection.Close();
}
else if (e.CommandName == "Delete")
{
string strSQL = "DELETE * FROM [User] WHERE UserId=@UserId";
OleDbConnection objConnection = new OleDbConnection(GetStrConnection());
OleDbCommand objCommand = new OleDbCommand(strSQL, objConnection);
objCommand.Parameters.Add("@UserId", OleDbType.Integer);
objCommand.Parameters["@UserId"].Value = int.Parse(e.CommandArgument.ToString());
objConnection.Open();
objCommand.ExecuteNonQuery();
objConnection.Close();
}
BindGrid();
}
private string GetStrConnection()
{
return "Provider=Microsoft.Jet.OleDb.4.0;data source=" + Server.MapPath("~/Database/test.mdb");
}
