推荐答案

您需要将它们构建为一个值，例如具有分隔符或XML的字符串.

You would need to build them in to one value, such as a string that has a seperator, or is XML.

试试这个

try this

CommandArgument=''<%#Eval("ENo") + ","+Eval("EValue") %>''

Protected Sub GridView1_RowCommand(sender As Object, e As GridViewCommandEventArgs)
    If e.CommandName = "Test" Then
        Dim commandArgs As String() = e.CommandArgument.ToString().Split(New Char() {","C})
      dim id as integer  = commandArgs(0)
     dim value as string  = commandArgs(1)
    End If
End Sub
