自定义数据源时，如何使用gridview 的功能按钮？[已结贴,结贴人:guostong]

// .aspx:

<asp:gridview id= "gv_master " runat= "server " autogeneratecolumns= "false "
width= "291px " datakeynames= "id ">
<columns>
<asp:boundfield datafield= "id " headertext= "id " />
<asp:boundfield datafield= "class " headertext= "class " />
<asp:boundfield datafield= "name " headertext= "name " />
<asp:commandfield showeditbutton= "true " />
</columns>
</asp:gridview>

// .cs

protected void page_load（object sender, eventargs e)
{
if （!ispostback)
{
gv_master.datasource = dmglobal.dttestproduct（);
gv_master.databind（);
}
}

在表格中按 "edit "按钮后得到如下异常：
the gridview 'gv_master ' fired event rowediting which wasn 't handled.
description: an unhandled exception occurred during the ＥＸＥＣution of the current web request. please review the stack trace for more information about the error and where it originated in the code.

exception details: system.web.httpexception: the gridview 'gv_master ' fired event rowediting which wasn 't handled.

source error:

an unhandled exception was generated during the ＥＸＥＣution of the current web request. information regarding the origin and location of the exception can be identified using the exception stack trace below.

但如果使用指定一个数据源就没有问题，请赐教

rowediting
把这个事件加上就应该可以了

.aspx:
<asp:gridview id= "gridview1 " runat= "server " onrowediting= "editing ">
　　 <columns>
　　　　 <asp:commandfield showeditbutton= "true " />
　　 </columns>
</asp:gridview>

.cs:
protected void editing（object sender, gridviewediteventargs e)
{
　　gridview1.editindex = e.neweditindex;

}

其他事件，如:delete,cancel,update也是相似的，如果还有什么不明白，查一下msdn
