GridView SelectedData键运行时错误. [英] GridView SelectedData key runtime error.

问题描述

您知道为什么此代码有错误吗?

字符串FolderID = grdCalls.SelectedDataKey [0] .ToString():-\

DO you know why this code have error

string FolderID = grdCalls.SelectedDataKey[0].ToString() :-\

推荐答案

字符串FolderID = grdCalls.SelectedDataKey [0] .ToString() "


它不会显示编译时错误，因为在编译时编译器不知道您是否使用了多个数据键.

即

"string FolderID = grdCalls.SelectedDataKey[0].ToString() "


It will not show you a Compile time error Because at a time of compilation compiler doesn''t know Either you have used multiple Datakeys or not.

i.e

DataKeyNames=CustID,ProductID

如果您使用了单个DataKeys 即

If you have used single DataKeys i.e

DataKeyNames = CustID

那么您就不需要在代码侧传递Index ，

如果您如上所述使用了多个键，则可以传递索引.

希望对您有所帮助.

then you dont need to pass Index at codeside,

You can pass the index if you have used multiple keys as described above.

Hope it helps.
