如何从后台，设置label的样式，设置成靠左，在td里

Question

我写成
 for (int i = 0; i < DataList1.Items.Count; i++)
            {
                Label textboxa = DataList1.Items[i].FindControl("Label11") as Label;
                TextBox textboxb = DataList1.Items[i].FindControl("TextBox11") as TextBox;
                if (textboxa.Text != textboxb.Text)
                {
                    textboxb.BackColor = System.Drawing.Color.Pink;
                    textboxa.BackColor = System.Drawing.Color.LightGreen;
                    textboxa.Visible = true;
                    textboxb.Visible = true;
                    textboxa.Style["float:left"];//怎么写让textboxa，在他所在的td里靠左？？
                }
            }

Answer 1

<tr><td align="left">（左对齐）</td>
看这代码就知道了吧？设置ＴＤ的属性　从后台获取ＴＤ　然后拼接字符串输出

Answer 2

TextBox1.Attributes.Add("style", "float:left")
foreach(DataListItem item in DataList1.Items)
{}

Answer 3

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            onrowdatabound="GridView1_RowDataBound">
            <Columns>
            <asp:TemplateField ItemStyle-Width="300" ItemStyle-HorizontalAlign="Center">
                <ItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("ID") %>'></asp:TextBox>
                </ItemTemplate>
            </asp:TemplateField>
            </Columns>           
        </asp:GridView>
 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
//没加这句的话是居中的，加了左靠齐
            e.Row.Cells[0].Style.Add("text-align", "left");
        }
    }

Answer 4

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            onrowdatabound="GridView1_RowDataBound">
            <Columns>
            <asp:TemplateField ItemStyle-Width="300" ItemStyle-HorizontalAlign="Center">
                <ItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("ID") %>'></asp:TextBox>
                </ItemTemplate>
            </asp:TemplateField>
            </Columns>           
        </asp:GridView>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />//在button事件中写
 protected void Button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            GridView1.Rows[i].Cells[0].Style.Add("text-align", "left");
        }
    }
