Enable client-side filtering in jqGrid's TreeGrid

由 [亡魂溺海] 提交于 2019-12-11 09:30:37
问题 With TreeGrid enabled in jqGrid, how can one create a work-around or customize the jqGrid source code so that the filter toolbar works properly on the client side? Out of the box, having TreeGrid enabled disables client-side filtering, paging, and client-side sorting. I was able to make simply adjustments to the jqGrid source code to solve the latter two issues. 回答1: The main problem with filtering of tree grid is just it's not clear what should be displayed as the result of filtering . I try

问题 Scenario is a Jqgrid treegrid with all nodes loaded, some of them collapsed some of them expanded as a result of user interaction. Now there is a need to scroll to a specific row based on the row ID, and if the row is inside a collapsed node, then expand the node till row is visible to the user. Any hints? 回答1: To expand the nodes of the TreeGrid you can use expandRow . One should additionally make a loop and expand all parents of the row. One can use getNodeParent to get direct parent.

问题 I have this problem, treegrid in jqGrid ignores the last option (expanded node or not) when passing data through xml. Anyone encountered this? Is there a solution? Maybe its my data? Here is a sample data that produces the problem: <rows> <page>1</page> <total>0</total> <records>4</records> <row id='2'> <cell>2</cell> <cell>Parent</cell> <cell>0</cell> <cell>NULL</cell> <cell>false</cell> <cell>true</cell> </row> <row id='1'> <cell>1</cell> <cell>Child 1</cell> <cell>1</cell> <cell>2</cell>

ASP.NET MVC + jqGrid without AJAX

由 醉酒当歌 提交于 2019-12-11 03:19:22
问题 I have an ASP.NET MVC application which is executing a search against a products database. I want to display the results in a jqGrid using the TreeGrid module. I don't really need the grid to be AJAX-y because the data is static and it is small enough that it can all be sent to the client at once. First question: how do I set up jqGrid so that instead of pulling the JSON data from a URL it just looks in a JS variable or something? Secondly, what is the most appropriate way to get ASP.NET MVC

easyui加载数据出错Cannot read property &apos;length&apos; of undef

Uncaught TypeError: Cannot read property 'length' of undefined: 例如:在treegrid的行编辑中,在执行了onAfterEdit()方法之后,会自动执行onLoadSuccess()方法,从服务器重新加载数据,如果服务器返回的数据为null,那么就会抛出这样一个错误, 源码为: var isArray = $.array.likeArray(data) && !$.util.isString(data), rows = isArray ? data : data.rows; f (!rows.length) { return data; }//这句话抛出错误,此错误会导致不会执行onLoadSuccess()方法,即页面的原有的数据不会发生改变 Uncaught TypeError: Cannot read property 'id' of undefined" 错误2: 这个错误很可能的原因是: --例如treegrid,异步加载树 代码: $("#xmzj").treegrid("expand", id);//展开该节点 $("#xmzj").treegrid("scrollTo",index);//滚动到行标为index的记录 $("#xmzj").treegrid("select", id);//选择记录 /
