VB.net Webform Gridview與復選框DataControlRowType

Question

VB.net Webform將數據從Sql數據庫提取到gridview。

我有兩個位列Rush和Normal-在后面的代碼中，如果選中Rush，則行單元格變為紅色，Normal變為藍色。

我的問題是，位是True還是False，將它們轉換為Integer或Int32的運氣不好。

這是我正在使用的代碼，如果單元格7不等於1，此代碼會將所有行變為藍色。

如果我轉到Rush cell（10）錯誤，則輸入的字符串格式不正確。

問題是如何將位從True / false轉換為1/0或正確格式。

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs)

    If e.Row.RowType = DataControlRowType.DataRow Then

        Dim sh As String = Convert.ToInt32(e.Row.Cells(7).Text)

        For Each cell As TableCell In e.Row.Cells
            If sh = 1 Then
                cell.BackColor = Drawing.Color.Red
            Else
                cell.BackColor = Drawing.Color.Blue

            End If

        Next


    End If



End Sub

為什么要轉換為整數，當您有位列時，請嘗試以下代碼。

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
    Dim sh As Boolean = Convert.ToBoolean(e.Row.Cells(7).Text)
    For Each cell As TableCell In e.Row.Cells
        If sh Then
            cell.BackColor = Drawing.Color.Red
        Else
            cell.BackColor = Drawing.Color.Blue
        End If
    Next
End If
End Sub

我想在這里有它，而不是與布爾值作斗爭，我決定將單元格更改為Integer。 請檢查並讓我知道您的想法。 它正常工作，緊急訂單為紅色，正常為藍色..

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs)


    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim Chkb As Integer = (e.Row.DataItem(10))

        For Each cell As TableCell In e.Row.Cells
            If Chkb = -1 Then
                cell.BackColor = Drawing.Color.Red
            Else
                cell.BackColor = Drawing.Color.Blue

            End If

        Next


    End If



End Sub
