如何动态地分配背景色到GridView行？ [英] How to dynamically assign a BackColor to a GridView row?

问题描述

我的工作包含一个GridView，其中填充有一个存储过程返回客户的订单一个ASP.Net页面上。我想要做的就是动态地改变在GridView行的背景色来指示优先级。

I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.

存储过程返回指示记录优先级的整数，我想我只需要整数转换为一种颜色，然后让在GridView行显示。

The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.

在造GridView的行显示它的部分是，公司给了我一个困难时期之一。

The "making the GridView row display it" part is the one that's giving me a hard time.

什么是做到这一点的最好方法是什么？谁能给我一个例子吗？

What's the best way to do this? Can anyone give me an example?

先谢谢了。

C＃：
ASPX：

C#: aspx:

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound" >
...
</asp:GridView>

codebehind：

codebehind:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int priority = (int)DataBinder.Eval(e.Row.DataItem, "priority");
        switch (priority)
        {
           case 1: 
              e.Row.BackColor = Drawing.Color.Green;
              break;
           case 2:
              e.Row.BackColor = Drawing.Color.Red;
              break;
           default:
              e.Row.BackColor = Drawing.Color.Black;
              break;
        }
    }
}

VB.Net codebehind：

VB.Net codebehind:

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
    Select Case e.Row.RowType
        Case DataControlRowType.DataRow
            Dim priority As Int32 = DirectCast(DataBinder.Eval(e.Row.DataItem, "priority"), Int32)
            Select Case priority
                Case 1
                    e.Row.BackColor = Drawing.Color.Green
                Case 2
                    e.Row.BackColor = Drawing.Color.Red
                Case Else
                    e.Row.BackColor = Drawing.Color.Black
            End Select
    End Select
End Sub
