DataGrid绑定数据时进行判断

Question

假设  一共3列数据  A,B,C
A,C是直接绑定显示<%#Eval("A") %>  <%#Eval("C") %>
B是textbox文本框<asp:TextBox ID="TextBox1" runat="server" Width="45"  Text='<%#Eval("B") %>'></asp:TextBox>我想在数据绑定的时候，判断，如果C=1，对应的B的文本框为不可修改，
如果C=2，对应的B的文本框正常可修改
问：需要写在哪个事件？如何写？
r是对象，不用在意，我下在下面这个事件里，但是没用，求教
Data_g_ItemDataBound
if (r.B== "1")
        {
            TextBox text = (TextBox)e.Item.FindControl("TextBox1");
            text.ReadOnly = false;
        }
        if (r.B== "2")
        {
            TextBox text = (TextBox)e.Item.FindControl("TextBox1");
            text.ReadOnly = true;
        }

Answer 1

asp.net GridView控件没有ItemDataBound事件。你的ItemDataBound那里来的？

Answer 2

webform的GridView控件要用RowBound事件我的测试代码
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            onrowdatabound="GridView1_RowDataBound">
            <Columns>
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:BoundField DataField="age" HeaderText="Age" />
                <asp:TemplateField HeaderText="Description">
                    
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server"  Text='<%# Eval("Description") %>' ></asp:TextBox>
                    </ItemTemplate>
                    
                </asp:TemplateField>
            </Columns>
        </asp:GridView>    public partial class WebForm3 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {            if (!IsPostBack)
            {
                List<Person> people = new List<Person>()
                {
                    new Person(){Name = "David", age = 10, description="this is kid"},
                    new Person(){Name = "Jack", age = 30, description="this is man"},
                    new Person(){Name = "Mary", age = 40, description="this is woman"},
                    new Person(){Name = "Mark", age = 3, description="this is baby"}                };                GridView1.DataSource = people;
                GridView1.DataBind();
            }        }        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                int age = int.Parse(e.Row.Cells[1].Text);
                if (age <= 5)
                {
                    TextBox descriptionControl = e.Row.FindControl("TextBox1") as TextBox;
                    if (descriptionControl != null)
                        descriptionControl.ReadOnly = true;
                }
                
            }        }
    }    class Person
    {
        public string Name { get; set; }
        public int age { get; set; }
        public string description { get; set; }
    }

Answer 3

rowdatabound事件
text.Enable = false;
