ASP.NET UpdatePanel 中的 GridView 直到第二次点击才会更新

ASP.NET GridView inside UpdatePanel doesn't update until second click

我在网上寻找答案,但没有找到任何答案。我在 UpdatePanel 和一个 Linkbutton 列中有一个 GridView,用于在 Bootstrap 模式中显示一些细节。我有一个问题,当用户点击 LinkBut​​ton 时,事件 OnClick 没有触发,所以,为了解决这个问题,我在 Javascript 中做了一个函数,它只会导致点击另一个 LinkBut​​ton 来触发 OnClick 事件。

现在它工作正常,但在第二次单击之前没有任何变化。

ASP.NET代码

<asp:UpdatePanel ID="upContent" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <table align="center">
            <tr>

Javascript代码

function ActivityLog(lbt) {
    lbt.nextSibling.nextSibling.click(); //Find the other LinkButton and click
}

C#代码

protected void ActivityLog_Click(object sender, EventArgs e)
{
    SqlDTSgetTracing.SelectParameters["ord_id"].DefaultValue = ((LinkButton)sender).Text;
    SqlDTSgetTracing.Select(DataSourceSelectArguments.Empty);
    grvLog.DataBind();
    upLog.Update();
}

When clicking the first time

When clicnking the seccond time

点击两次后,数据显示在 GridView 中。

我希望从第一次单击开始就在 GridView 中显示数据。

我认为您可能希望将 return false; 附加到 OnClientClick 的末尾,以防止该控件的其余单击事件(由 ASP.NET 为您编码)来自 运行.这将确保只有您关心的 LinkButton 会回发。

OnClientClick="ActivityLog(this);return false;"

不确定这是否会解决点击两次的问题,但也许吧!
