        SqlConnection con = new SqlConnection(strconnstring);
        SqlDataAdapter sda = new SqlDataAdapter();
        cmd.CommandType = CommandType.Text;
        cmd.Connection = con;

        try

            //GridView2.DataBind();
            dl_channels.DataSource = dt;
            dl_channels.DataBind();

        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }
        finally
        {
            con.Close();
            sda.Dispose();
            con.Dispose();

我们假设你有一个Gridview，其复选框如下：

 <asp:GridView ID="GridView1" runat="server">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:CheckBox ID="checkIT" runat="server"/>
                </ItemTemplate>
            </asp:TemplateField>
    </asp:GridView>

 <asp:Button ID="btnDisplay" runat="server" Text="Show data selected"  OnClick="btnDisplay_Click"/>    

<asp:TextBox id="textboxDataDisplay" runat="server" />

带一个按钮，显示所选的复选框列

C＃代码

protected void btnDisplay_Click(object sender, EventArgs e)
{
    string data = "";

    foreach (GridViewRow row in GridView1.Rows)
    {
            if (row.RowType == DataControlRowType.DataRow)
            {
                CheckBox chkRow = (row.Cells[0].FindControl("chkCtrl") as CheckBox);
                if (chkRow.Checked)
                {
                    string yourFirstRowCell = row.Cells[1].Text;
                    string yourSecondRowCell = row.Cells[2].Text;
                    string yourThirdRowCell = row.Cells[3].Text;
                    data = yourFirstRowCell + yourSecondRowCell + yourThirdRowCell; 
                }
            }
    }

    textboxDataDisplay.text = data; 
}

行单元格是您要获取复选框所在行的单元格。
