BoundField如何控制数据?

在一个gridview中,第一列是TemplateField,放一个checkbox,后面五列是BoundField,直接绑订数据库。

我想控制改变最后一列的显示,如果从数据库拿到的数据是's',那么显示文字‘储存’,如果是‘P’那么显示‘批稿’。它后台直接就绑订了datasource,我现在应该如何控制?代码怎么写啊?

.aspx

<asp:GridView ID="gvDiff" runat="server" AutoGenerateColumns="False">
                        <Columns>
                            <asp:TemplateField>
                                <ItemTemplate>
                                    <asp:CheckBox runat="server" ID="cbSelectVersion"></asp:CheckBox>
                                </ItemTemplate>
                                <ItemStyle Width="5%" />
                            </asp:TemplateField>
                            <asp:BoundField DataField="RevNo" HeaderText="<%$ Resources: RevNo %>" />
                            <asp:BoundField DataField="Remarks" HeaderText="<%$ Resources: Action %>" />
                            <asp:BoundField DataField="UpdatedDate" HeaderText="<%$ Resources: UpdateDate %>" />
                            <asp:BoundField DataField="UpdateName" HeaderText="<%$ Resources: UpdateBy %>" />
                            <asp:BoundField DataField="Status" HeaderText="<%$ Resources: ArticlePosition %>" />
                        </Columns>
                    </asp:GridView>
                    <asp:GridView ID="gvResult" runat="server" ShowHeaderWhenEmpty="True" Visible="true">
                    </asp:GridView>

aspx.cs

public override void DataBind() {
            if (DataSource != null) {
                articles = DataSource;
                gvDiff.DataSource = DataSource.ArticleHistories;
                gvDiff.DataBind();
            }

        }

能具体点吗?我没台明白你讲的

rivahuang | 园豆:91 (初学一级) | 2015-11-12 16:17

@rivahuang: RowDataBound

jello chen | 园豆:7091 (大侠五级) | 2015-11-12 16:27

@jello chen: 

 protected void gvRowDatabound(object sender, GridViewRowEventArgs e)
        { 
            for(int i=0;i<=gvDiff.Rows.Count;i++)
            {
                if (!string.IsNullOrWhiteSpace(gvDiff.Rows[0].Cells[5].ToString()))
                {
                    switch (gvDiff.Rows[0].Cells[5].ToString())
                    {
                        case "A": gvDiff.Rows[i].Cells[5].Text = "";
                            break;
                        case "S": gvDiff.Rows[i].Cells[5].Text = "";
                            break;
                        case "N": gvDiff.Rows[i].Cells[5].Text = "";
                            break;
                        case "P": gvDiff.Rows[i].Cells[5].Text = "";
                            break;
                    }
                }
            }
        }

你的意思是这样子写?

@rivahuang: 不需要遍历啊,通过GridViewRowEventArgs事件参数e可以获取该行的数据,然后根据数据来决定相应的变化

@jello chen: 可以简单的给我写一写吗?

@rivahuang:

aspx页面:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowDataBound="GridView1_OnRowDataBound">
            <Columns>
                <asp:BoundField DataField="No" HeaderText="No"></asp:BoundField>
                <asp:BoundField DataField="Name" HeaderText="Name"></asp:BoundField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="btn" runat="server"/>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

Codebehind:

public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            List<Student> students = new List<Student>();
            for (int i = 0; i < 10; i++)
            {
                students.Add(new Student() { No = i + 1, Name = "zhangsan" + (i + 1) });
            }
            GridView1.DataSource = students;
            GridView1.DataBind();
        }

        protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
        {
            var student = e.Row.DataItem as Student;
            if (student != null)
            {
                var btn = e.Row.FindControl("btn") as Button;
                if (btn != null)
                {
                    if (student.No % 2 == 0)
                    {
                        btn.Text = "偶行";
                    }
                    else
                    {
                        btn.Text = "奇行";
                    }
                }
            }
        }
    }

    class Student
    {
        public int No { get; set; }
        public string Name { get; set; }
    }
