Repeater控件实现编辑、更新、删除操作

如何在Repeater控件中实现像GridView控件一样的编辑、更新、删除功能？

下面给出示例 vs.net2008(C#)下编写。来自 admin10000.com

后台.cs代码

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");

}
