ASP.NET gridview 禁用行保留第一列

Question

我的网格视图在第一列中有复选框。单击复选框时，我想禁用该行，但保持启用复选框。

此代码禁用整行，包括复选框：

protected void chkRow_CheckedChanged(object sender, EventArgs e)
{
     CheckBox chkRow = (CheckBox)sender;
     GridViewRow row = (GridViewRow)chkRow.NamingContainer;

     if (chkRow.Checked)
     {
         // Enable the row
         row.Enabled = false;
         row.Style["background-color"] = "#F5F5F5";
         chkRow.Enabled = true;
     }
     else
     {
         // ....
     }
}

好的，所以说这个标记：

<asp:GridView ID="GVHotels" runat="server" AutoGenerateColumns="False"
    DataKeyNames="ID" 
    CssClass="table table-hover" 
    width="50%">
    <Columns>
        <asp:TemplateField HeaderText="Select" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate > 
                <asp:CheckBox ID="chkRow" runat="server"
                    OnCheckedChanged="chkRow_CheckedChanged"
                    AutoPostBack="true" />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="FirstName" HeaderText="FirstName" />
        <asp:BoundField DataField="LastName" HeaderText="LastName" />
        <asp:BoundField DataField="City" HeaderText="City" />
        <asp:BoundField DataField="HotelName" HeaderText="HotelName" />
        <asp:TemplateField HeaderText="Description">
            <ItemTemplate>
                <asp:TextBox ID="txtDesc" runat="server"
                    TextMode="MultiLine" Rows="4" Width="100%"
                    Text='<%# Eval("Description") %>'>
                </asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

加载后面的代码，并处理复选框：

    protected void Page_Load(object sender, EventArgs e)
    {

        if (!IsPostBack)
            LoadGrid();

    }

    void LoadGrid()
    {
        string strSQL =
            @"SELECT * FROM tblHotelsA
            WHERE Description is not null
            AND Active = 1
            ORDER BY HotelName";

        GVHotels.DataSource = General.MyRst(strSQL);
        GVHotels.DataBind();
    }

    protected void chkRow_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkRow = (CheckBox)sender;
        GridViewRow row = (GridViewRow)chkRow.NamingContainer;

        if (chkRow.Checked)
            row.Style["background-color"] = "skyblue";  // color row for checked box
        else
            row.Style["background-color"] = "white";  // color row for un-checked box

        // now disable all controls in row EXACPT for first cell (checkbox)
        for (int i=1;i < row.Cells.Count;i++)
            row.Cells[i].Enabled = !chkRow.Checked;

    }

因此，我们只需禁用（或启用）该给定行中的所有单元格，跳过包含复选框控件的第一个单元格，即可代替“整”行禁用。

结果是这样的：
