带有DDL的ASPX DetailsView更新为SQL问题

[英]ASPX DetailsView with DDL update to SQL Issue

原文 2017-10-04 09:52:24 7 1 javascript/ c#/ jquery/ asp.net/ drop-down-menu

Trying to find out if I am approaching this right (NOOB so be patient plz!) I'm trying to write a single aspx page with UserList1 (bind to SQLSource1.displayname) which updates DetailsView1 (Edit Enabled, SQLSource2 where displayname=@displayname). 试图找出我是否正在接近这个权利（NOOB，请耐心等待！），我试图用UserList1（绑定到SQLSource1.displayname）编写一个aspx页面，该页面更新DetailsView1（启用Edit，SQLSource2，其中displayname = @ displayname ）。 Display name and Dept fields are read-only, yesno needs to updated. 显示名称和部门字段是只读的，不需要更新。 If I leave the stock edit textbox it updates fine. 如果我离开股票编辑文本框，它会更新正常。 End users being end users we want to give them limited options for the update so I want to replace the textbox with a DDL ... Change YESNO field templatefield, add DDL which has YES or NO option, Postback=enabled. 最终用户是最终用户，我们希望为他们提供有限的更新选项，因此我想用DDL替换文本框...更改YESNO字段templatefield，添加具有YES或NO选项的DDL，启用Postback =启用。

Unbound I get "Cannot insert the value NULL into column 'yesno' .... 未绑定，我得到“无法将值NULL插入列'yesno'...。

Bind("yesno") I get "Conversion from string "YES" to type 'Integer' is not valid" Bind（“ yesno”）我收到“从字符串“ YES”到类型“ Integer”的转换无效”

1st error - I probably need to catch the selected text of the DDL selection to do the update statement ?? 第一个错误-我可能需要捕获DDL选择的选定文本来执行更新语句？ Code behind or Javascript/Jquery? 代码落后还是Javascript / Jquery？

2nd error - why is converting the selection to Integer - SQL column type is text? 第二个错误-为什么将选择转换为整数-SQL列类型为text？

TIA Guys ! TIA伙计们！
