Question

背後，這是我的.aspx頁面代碼： -

<asp:Button ID="btnProcess" runat="server" Text="Place" OnClick="btnProcess_Click" 
CommandArgument='<%# Eval("intId") & "~" & Eval("IdECompleted") & "~" & Eval("dtECompletion") & "~" & Eval("strName") & " " & Eval("strCode") & " " & Eval("strAge") & " " & Eval("strGender") & "~" & Eval("dtStart") & "~" & Eval("strContactP") & "~" & Eval("strAdd") & "~" & Eval("strPhone") & "~" & Eval("intSalary") & "~" & Eval("bitAgree") %> /> 

</ItemTemplate> 
</asp:TemplateField> 
</Columns> 
</asp:GridView> 

我想用它像下面，但得到的錯誤： -

Private Sub Grd_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Grd.RowDataBound 
If Session("poweradmin") = True Then 
      Dim btnProcess As New Button 
      btnProcess = CType(e.Row.FindControl("btnProcess"), Button) 

      btnProcess.CommandArgument = "<% #Eval("intId") & "~" & Eval("IdECompleted") & "~" & Eval("dtECompletion") & "~" & Eval("strName") & " " & Eval("strCode") & " " & Eval("strAge") & " " & Eval("strGender") & "~" & Eval("dtStart") & "~" & Eval("strContactP") & "~" & Eval("strAdd") & "~" & Eval("strPhone") & "~" & Eval("intSalary") & "~" & Eval("bitAgree") %>'" 

     End If 
End Sub

      End If 
     End If 
    End Sub

您不能使用字符串表達式，但可以評估cod中的表達式e後面：

btnProcess.CommandArgument = DataBinder.Eval(e.Row.DataItem, "intId") & " ~ " & DataBinder.Eval(e.Row.DataItem, "IdECompleted")
