问题描述

如何编写linqdatasource _inserting (object sender,linqDatasourceInsertEvent args)?

我使用详细视图(已经从masterview中选择)，但是当我写回sql时，我将采用session[userid]或master gridview1.[userId]选定的值.

还是只是简单地用LinquDataSourceInsertEvent要求Linqdatasoure的插入功能?

How to write a linqdatasource _inserting (object sender,linqDatasourceInsertEvent args)?

I use a detail view (select from masterview already), but when i write back to sql i will take either a session[userid] or master gridview1.[userId] selected value.

Or just simply ask for Inserting function for Linqdatasoure with LinquDataSourceInsertEvent?

推荐答案

我发现在msdn上，也许有帮助吗?

I found that on msdn, maybe help ?

protected void LinqDataSource_Inserting(object sender, LinqDataSourceInsertEventArgs e)
{
    Product product = (Product)e.NewObject;
    product.DateModified = DateTime.Now;
}

protected void LinqDataSource_Inserting(object sender,
        LinqDataSourceInsertEventArgs e)
{
    if (e.Exception != null)
    {
        foreach (KeyValuePair<string, Exception> innerException in
             e.Exception.InnerExceptions)
        {
        Label1.Text += innerException.Key + ": " +
            innerException.Value.Message + "<br />";
        }
        e.ExceptionHandled = true;
    }
}
