Question

我知道这个问题之前已被问过几次，我尝试了很多建议的解决方案。我试图加粗我的GridView的每一行，其中包含文本“已获得”或“总计”（尚未添加“总计”代码）。我已经成功地获取了DataBound事件，并且我已经成功地识别出我用于遍历每一行和每列的2 For循环语句（我使用标签让我知道我访问过的代码块和计数是24行和9列），但由于某种原因，我用来专门确定单元格是否包含“获得”文本的代码不会触发。我不确定我做错了什么。有人可以看一看，帮助我理解我做错了什么吗？谢谢你的帮助！

这是我的GridView的ASP代码（对不起，不知道为什么它在多个块中）：

这是我的DataBound代码：

Public Sub gv_VacationDetails_DataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    Label6.Text = "Inside Bold"
    'Label6.Text = gv_VacationDetails.Rows(1).Cells("Action").Text.ToString
    Dim r As Integer
    Dim c As Integer

    For r = 0 To gv_VacationDetails.Rows.Count - 1
        Label6.Text = "Inside ROW"
        For c = 0 To gv_VacationDetails.Columns.Count - 1
            Label6.Text = "Inside COLUMN"
            Label7.Text = "Rows = " & CType(gv_VacationDetails.Rows.Count - 1, String) & ";  Columns = " & CType(gv_VacationDetails.Columns.Count - 1, String)
            If gv_VacationDetails.Rows(r).Cells(c).Text.Trim = "Earned" Then
                Label6.Text = "Inside BOLD IF"
                gv_VacationDetails.Rows(r).Cells(c).Font.Bold = True
                'gv_VacationDetails.Rows(r).Cells(c).ForeColor = Drawing.Color.Red
            End If
        Next
    Next

    'For i = 1 To gv_VacationDetails.Rows.Count - 1
    '    'Label6.Text = gv_VacationDetails.Rows(i).Cells(1).Text.ToString
    '    If gv_VacationDetails.Rows(i).Cells(0).Text = "Earned" Then
    '        Label6.Text = "Inside Bold IF"
    '        gv_VacationDetails.Rows(i).Font.Bold = True
    '    End If
    'Next

    'If e.Row.RowType = DataControlRowType.DataRow Then
    '    Label6.Text = "Inside Bold IF"
    '    Dim drv As DataRowView = CType(e.Row.DataItem, DataRowView)
    '    If CType(drv(0), String) = "Earned" Or CType(drv(0), String) = "Total Adjustments" Or _
    '        CType(drv(0), String) = "Total Used" Or CType(drv(0), String) = "Total Remaining" Then
    '        e.Row.Font.Bold = True

用于访问GridView行单元格的方法仅适用于绑定字段而非模板字段。要访问模板字段，您可以使用 Row.FindControl 方法。

请在您的gv_VacationDetails_DataBound方法中尝试此操作：

Public Sub gv_VacationDetails_DataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)

    If e.Row.RowType = DataControlRowType.DataRow Then

        'First you need to get the template fields, which are labels as in GridView your design
        Dim Label1 As Label = DirectCast(e.Row.FindControl("Label1"), Label)
        Dim Label2 As Label = DirectCast(e.Row.FindControl("Label2"), Label)
        Dim Label3 As Label = DirectCast(e.Row.FindControl("Label3"), Label)
        Dim Label4 As Label = DirectCast(e.Row.FindControl("Label4"), Label)

        'Next you can check each field value
        If Label1.Text = "Earned" Then
            Label1.Font.Bold = True
        End If

        If Label2.Text = "Earned" Then
            Label2.Font.Bold = True
        End If

        If Label3.Text = "Earned" Then
            Label3.Font.Bold = True
        End If

        If Label4.Text = "Earned" Then
            'Label6.Text = "Inside BOLD IF"
            Label4.Font.Bold = True
        End If

        'You can check the bound fields by looping through row cells
        For Each cell As TableCell In e.Row.Cells
            If cell.Text = "Earned" Then
                cell.Font.Bold = True
            End If
        Next

    End If

End Sub
