Repeater控件实现编辑、更新、删除等操作示例代码

复制代码 代码如下:

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
string strSQL = "SELECT * FROM [User]";

objConnection.Open();

rptUser.DataSource = reader;
rptUser.DataBind();
}
protected void rptUser_ItemDataBound(object sender, RepeaterItemEventArgs e)
{

{
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("plEdit")).Visible = false;
}
else
{

}
}
}

{

}

}

}
