Question

我有一个将AutoGenerateColumns设置为FALSE的gridview。我手动添加了列（BoundField和ButtonField）以确保按钮显示在最后一列，因为如果AutoGenerateColumns设置为TRUE，则添加的ButtonField的默认位置位于第一列。

如果将AutoGenerateColumns设置为TRUE，则以下代码可以正常工作。但是，如果我将其更改为false并添加BoundFields和ButtonField，则它不起作用。查询工作正常，如果AutoGenerateColumns设置为TRUE，我已经看到Gridview填充没有问题。

请协助解决问题。我希望按钮位于列的右侧。因此，下面的aspx设计。

代码：

<asp:GridView ID="GridView1" runat="server" BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Vertical" Width="100%" EmptyDataText="No records to display." AutoGenerateColumns="False">
    <AlternatingRowStyle BackColor="White" />
    <Columns>
        <asp:BoundField HeaderText="COL1" />
        <asp:BoundField HeaderText="COL2" />
        <asp:BoundField HeaderText="COL3" />
        <asp:BoundField HeaderText="COL4" />
        <asp:BoundField HeaderText="COL5" />
        <asp:ButtonField ButtonType="Button" Text="Update"/>
    </Columns>
    ........
 </asp:GridView>


DataTable GetData()
{
    DataTable dt = new DataTable();
    string LoginDbCS = ConfigurationManager.ConnectionStrings["UserDetails"].ConnectionString;
    SqlConnection Conn = new SqlConnection(LoginDbCS);
    SqlCommand Command = new SqlCommand("SELECT [COL1], [COL2], [COL3], [COL4], [COL5] FROM dbo.tableUser WHERE @User = Username", Conn);

    try
    {
        Conn.Open();
        Command.Parameters.Add("User", SqlDbType.NVarChar).Value = Username;

        SqlDataAdapter adpt = new SqlDataAdapter(Command);
        adpt.Fill(dt);
        Conn.Close();
    }
    catch (Exception Er)
    {
        ....
        if (Conn != null)
            Conn.Dispose();
        }
        ....
    }
    return dt;
}

protected void Page_Load(object sender, EventArgs e)
{
    ....
    GridView1.DataSource = GetData();
    GridView1.DataBind();
    ....
}

试试这个

<asp:GridView ID="GridView1" runat="server" BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Vertical" Width="100%" EmptyDataText="No records to display." AutoGenerateColumns="False">
    <AlternatingRowStyle BackColor="White" />
    <Columns>
        <asp:BoundField DataField="COL1" HeaderText="COL1" />
        <asp:BoundField DataField="COL2" HeaderText="COL2" />
        <asp:BoundField DataField="COL3" HeaderText="COL3" />
        <asp:BoundField DataField="COL4" HeaderText="COL4" />
        <asp:BoundField DataField="COL5" HeaderText="COL5" />
        <asp:CommandField ShowSelectButton="True" SelectText="Update"/>
    </Columns>
    ........
 </asp:GridView>

然后为SelectedIndexChanged创建一个事件来处理选定的行

在Gridview的右端添加按钮
