当我触发回发时，会显示转发器中的Gridview [英] Gridview in repeater is shown when I fire postback

问题描述

我有下拉列表（ddl）和转发器（rptPayment）。

I have dropdownlist (ddl) and repeater(rptPayment) .

on

 protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
    {
BindRepeater();
}

绑定中继器成功。



在转发器中我隐藏并在检查时显示gridview盒子检查。

它正常工作。

Bind Repeater successfully.

In repeater when i hide and show gridview on check box checked.
It is working.

 function hideshowGV(itemId, itemIndex) {
            if (document.getElementById("ContentPlaceHolder1_rptPayment_chkComm_" + itemIndex).checked == true) {
                document.getElementById(itemId + "_gvPayment_" + itemIndex).style.display = 'block';
}
else {
                document.getElementById(itemId + "_gvPayment_" + itemIndex).style.display = 'none';
}
}

但是当我再发一次回发它（gridview）再次显示时，即使复选框也没有检查。

我尝试了什么：

What I have tried:

<table align="center" style="width: 100%">
        <tr>
<td>         
                                    <asp:DropDownList ID="ddl" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddl_SelectedIndexChanged"

                                        Width="200px">

推荐答案

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)

不调用

function hideshowGV(itemId, itemIndex)

如果在代码中设置断点，您将看到发生了什么。 使用Visual Studio 2010进行基本调试 - YouTube [ ^ ]

<asp:UpdatePanel ID="UpdatePanel6" runat="server" UpdateMode="Conditional">

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
    {
UpdatePanel6.Update();
BindRepeater();
}
