我正在寻找有关添加行按钮的帮助，我在插入数据时遇到了问题。
这是我收到的错误：
错误 1：方法 'Protected Sub SqlDataSource2_Inserting(sender As Object, e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs)' 无法处理事件'Public Event Inserting(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs)'因为它们没有兼容的签名。C:\Users\Administrator\Documents\Visual Studio 2012\Projects\Certificates\Certificates\WebForm1.aspx.vb 17 161 证书
