我的 GridView 基本上显示了数据库中数据的汇总版本。
我想要做的是设置它,以便当您单击 GridView 中一行中的任意位置时,它应该执行一个设置过程,该过程将隐藏包含 GridView 的面板并显示一个面板,该面板将显示您的详细信息您点击的项目。
<asp:Panel runat="server" ID="pnlList">
<div class="rightalign">
<asp:Label runat="server" ID="lblCount"></asp:Label>
</div>
<asp:GridView runat="server" ID="gvItems" DataKeyNames="mailid"
AutoGenerateColumns="false" onrowdatabound="gvItems_RowDataBound"
Width="100%" OnSelectedIndexChanged="gvItems_SelectedIndexChanged">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox runat="server" ID="chkSelect" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lblStatus" Text='<%# DataBinder.Eval(Container.DataItem, "status") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="firstname" HeaderText="From" SortExpression="firstname" />
<asp:BoundField DataField="datesent" HeaderText="Date" SortExpression="datesent" DataFormatString="{0:yyyy/MM/dd HH:mm}" />
<asp:BoundField DataField="subject" HeaderText="Subject" SortExpression="subject" />
</Columns>
</asp:GridView>
</asp:Panel>
<asp:Panel runat="server" ID="pnlMail">
<p>From: <asp:Label runat="server" ID="lblFrom"></asp:Label><br />
Sent On: <asp:Label runat="server" ID="lblDate"></asp:Label><br />
Subject: <asp:Label runat="server" ID="lblSubject"></asp:Label></p>
<p><asp:Label runat="server" ID="lblMessage"></asp:Label></p>
</asp:Panel>
我想我会使用这个SelectedIndexChanged
事件,但我不确定如何让它真正触发对单元格的点击。
这是我得到的代码:
protected void gvItems_SelectedIndexChanged(object sender, EventArgs e)
{
int index = gvItems.SelectedIndex;
string mailid = gvItems.DataKeys[index].Value.ToString();
getMailDetail(mailid);
pnlMail.Visible = true;
}
protected void getMailDetail(string id)
{
int mailid = int.Parse(id);
MySqlContext db = new MySqlContext();
string sql = "select m.datesent, m.subject, m.message, u.firstname, u.lastname from mail m inner join users u on m.senderid = u.userid where m.mailid = @id";
List<MySqlParameter> args = new List<MySqlParameter>();
args.Add(new MySqlParameter() { ParameterName = "@id", MySqlDbType = MySqlDbType.Int32, Value = mailid });
MySqlDataReader dr = db.getReader(sql, args);
if (dr.HasRows)
{
dr.Read();
lblFrom.Text = (string)dr["firstname"] + " " + (string)dr["lastname"];
lblDate.Text = (string)dr["datesent"];
lblSubject.Text = (string)dr["subject"];
lblMessage.Text = (string)dr["message"];
}
dr.Close();
}
如何使连续单击单元格触发一个事件,该事件将完成我需要完成的工作?
任何帮助将不胜感激!
