asp.net - 如何根据其值更改gridview单元格背景颜色

Question

我需要更改 gridview 单元格的背景颜色，但它不起作用。

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView2.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        For Each er As GridViewRow In GridView2.Rows
            If er.Cells(4).Text = "Formation" Then
                er.Cells(4).BackColor = Color.Red
            End If
        Next
    End If
End Sub

如何根据单元格的值更改单元格的背景颜色？

Answer 1

试试这个:

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView2.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
            If e.Row.Cells(4).Text = "Formation" Then
                e.Row.Cells(4).BackColor = Color.Red
            End If
    End If
End Sub

同时放置一个断点

If e.Row.Cells(4).Text = "Formation" Then

并检查e.Row.Cells(4).Text的值并确保它确实="Formation"，也许您需要获取该值Cells(4) 中的标签。
