Question

VB.net webform将数据从Sql数据库提取到gridview。

我有两个位列Rush和Normal - 在后面的代码中，如果Rush被检查，则行单元格变为红色，而正常变为蓝色。

我遇到的问题是该位是真还是假没有太多运气将它们转换为Integer或Int32。

这是我正在使用的代码，如果单元格7不等于1，此代码将所有行变为蓝色。

如果我去Rush cell（10）错误输入字符串的格式不正确。

问题是如何将位从True / false转换为1/0或正确的格式。

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

Answer 1

为什么要转换为整数，当您有位列时，请尝试使用以下代码。

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

我想我在这里，而不是与布尔战斗，我决定将单元格更改为整数。请检查并让我知道你的想法。它有效，拉什订单是红色，正常是蓝色..

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
