Question

我想檢查每行的單元格（3）中的日期。如果第一個If條件成立，我只能得到日期，其餘的單元格顯示爲空白。代碼如下。

 For Each row As GridViewRow In GridView1.Rows 
      If Not IsDBNull(dr("B1Week").ToString) Then 
       e.Row.Cells(3).Text = dr("B1week").ToString 
       e.Row.Cells(3).ForeColor = System.Drawing.Color.Blue 

      ElseIf DD2 <= Now Then 
       e.Row.Cells(3).Text = e.Row.Cells(3).Text & " - OVERDUE" 
       e.Row.Cells(3).ForeColor = System.Drawing.Color.Red 

      ElseIf DD2 <= Now.AddDays(7) Then 
       e.Row.Cells(3).Text = e.Row.Cells(3).Text & " - DUE " 
       e.Row.Cells(3).ForeColor = System.Drawing.Color.Green 

      End If 

     Next row 

我希望檢查每行中的每個單元格3並分配值。誰能幫忙？

裏面你爲每個需要使用行變量循環：

For Each row As GridViewRow In GridView1.Rows 
     If Not IsDBNull(dr("B1Week").ToString) Then 
      row.Cells(3).Text = dr("B1week").ToString 
      row.Cells(3).ForeColor = System.Drawing.Color.Blue 

     ElseIf DD2 <= Now Then 
      row.Cells(3).Text = e.Row.Cells(3).Text & " - OVERDUE" 
      row.Cells(3).ForeColor = System.Drawing.Color.Red 

     ElseIf DD2 <= Now.AddDays(7) Then 
      row.Cells(3).Text = e.Row.Cells(3).Text & " - DUE " 
      row.Cells(3).ForeColor = System.Drawing.Color.Green 

     End If 

    Next row
