c# - 将 onclientclick 添加到 gridview 寻呼机

Question

在寻呼机中使用 asp.net 和 gridview 控件。

我如何向它添加一个 onclientclick，以便它只会在 onclientclick 返回 true 时页面。

这是可能的，因为它可以通过链接完成吗？

我知道我可以做到这一点

GridView pager page buttons accessibility

myGridView.Attributes.Add("onClick", "setOKToClose();")但它会将它添加到网格中，我希望它只添加到寻呼机中

谢谢

将您的寻呼机转换为模板，但您必须制定自己的逻辑来显示和管理页面索引。

这里是示例代码

    <PagerTemplate>
                        <asp:Panel ID="gvpanel" runat="server">
                            <table cellpadding="3" cellspacing="3" class="style4">
                                <tr>
                                    <td width="20%">
                                        <asp:Label ID="Label4" runat="server" CssClass="lb" Text="Page "></asp:Label>
                                        <asp:DropDownList ID="ddpage" runat="server" AutoPostBack="True" CssClass="txt" 
                                            onselectedindexchanged="ddpage_SelectedIndexChanged">

                        </asp:Panel>
                    </PagerTemplate>

这是c#代码

        protected void lbp10_Click(object sender, EventArgs e)
{
    GridView1.PageIndex = (GridView1.PageIndex - 10);
    bind();
}
protected void lbp_Click(object sender, EventArgs e)
{
    GridView1.PageIndex = (GridView1.PageIndex - 1);
    bind();
}
protected void lbn_Click(object sender, EventArgs e)
{
    GridView1.PageIndex = (GridView1.PageIndex + 1);
    bind();
}
protected void lbn10_Click(object sender, EventArgs e)
{
    GridView1.PageIndex = (GridView1.PageIndex + 10);
    bind();
}
protected void lb1_Click(object sender, EventArgs e)
{
    LinkButton lb = (LinkButton)sender;
    GridView1.PageIndex = (int.Parse(lb.Text) - 1);
    bind();
}

创建页脚的代码

     void addfooter(int rcount)
{
    if (GridView1.BottomPagerRow == null)
    {
        return;
    }
    Panel p = (Panel)GridView1.BottomPagerRow.FindControl("gvpanel");

    DropDownList dd = (DropDownList)p.FindControl("ddpage");
    for (int i = 0; i < rcount; i++)
    {
        ListItem li = new ListItem();
        li.Text = (i + 1).ToString();
        li.Value = (i + 1).ToString();
        dd.Items.Add(li);
    }
    Label lbltot = (Label)p.FindControl("lbltot");
    lbltot.Text = GridView1.PageCount.ToString();
    dd.SelectedIndex = GridView1.PageIndex;
    LinkButton lbp10 = (LinkButton)p.FindControl("lbp10");
    lbp10.Enabled = false;
    lbp10.CssClass = "smalllinkbuttonfd";

        lb.CssClass = "smalllinkbuttonfd";
    }
    int tstart = cpage / 10;
    int lcount = tstart + 10;
    //int scount = tstart - 10;
    int cnt = 1;
    for (int i = (tstart * 10); i <= ((tstart * 10) + 10); i++)
    {
        if (cnt > 10)
        {
            return;
        } if ((i + 1) > totpage)
        {
            LinkButton lb = (LinkButton)p.FindControl("lb" + cnt.ToString());
            lb.Enabled = false;
            lb.Text = (i + 1).ToString();
            lb.CssClass = "smalllinkbuttonfd";
            cnt++;
        }
        else
        {
            if ((i + 1) == cpage)
            {
                LinkButton lb = (LinkButton)p.FindControl("lb" + cnt.ToString());
                lb.Enabled = false;
                lb.Text = (i + 1).ToString();
                lb.CssClass = "smalllinkbuttonfd";
                cnt++;
            }
            else
            {
                LinkButton lb = (LinkButton)p.FindControl("lb" + cnt.ToString());
                lb.Enabled = true;

}

Onlink按钮现在可以添加onclientclick
