将onClick添加到Infragistics WebDataGrid

Question

I have an Infragistics WebDataGrid and I want to fire a server side event every time a cell is clicked on. 我有一个Infragistics WebDataGrid，我想每次单击一个单元格时都触发一个服务器端事件。 I know that I can make a button and add an onclick to that, but I want some or all the data cells to be clickable. 我知道我可以创建一个按钮并向其中添加一个onclick，但是我希望某些或所有数据单元都是可单击的。 I also saw this( https://www.infragistics.com/community/forums/f/ultimate-ui-for-asp-net/108226/onclick-event-for-webdatagrid ) but I need the event to fire server side. 我也看到了这个（ https://www.infragistics.com/community/forums/f/ultimate-ui-for-asp-net/108226/onclick-event-for-webdatagrid ），但是我需要事件来触发服务器端。

You can try the following: 您可以尝试以下方法：

Handle "Click" client event and call __doPostBack js function to trigger a postback. 处理“ Click”客户端事件，并调用__doPostBack js函数来触发回发。 Page_Load server event will help you to determine whether the postback is caused by the click or not. Page_Load服务器事件将帮助您确定回发是否是由单击引起的。 Things to consider, client event "Click" will be fired on every click inside the Grid, have a look at the provided API link for more info. 要考虑的事情是，在网格内部的每次点击都会触发客户端事件“点击” ，请查看提供的API链接以获取更多信息。
Activate Selection behavior, and handle CellSelectionChanged client event. 激活选择行为，并处理CellSelectionChanged客户端事件。 From here use the approach with __doPostBack . 从这里开始，使用__doPostBack方法。

The Grid is very powerful control with a rich API and the behaviors, so we could thing of a different way to achieve this. Grid是一个非常强大的控件，具有丰富的API和行为，因此我们可以采用另一种方式来实现这一目标。

<script>
        function client_click(sender, evtArgs) {
            // First Approach
            __doPostBack('myRequest', "someValue");
        }

        function WDG_Selection_CellSelectionChanged(sender, eventArgs)
        {
            // Second Approach
            __doPostBack('myRequest', "someValue");
        }
