[英]Adding row to a ListGrid at a specified index Smart GWT

原文 2017-10-11 15:03:36 9 1 java/ gwt/ smartgwt/ smartgwt-pro

Currently I'm working on a listgrid which is editable and my requirement is to create aa new row every time a user selects a row and presses the "Create" Button. 目前，我正在研究一个可编辑的列表网格，我的要求是每次用户选择一行并按下“创建”按钮时都创建一个新行。 The new row needs to be added immediately below the selected row. 新行需要立即添加到所选行的下方。 I tried using the below method 我尝试使用以下方法

ListGrid.getRecordList().addAt(ListGridRecord rec, Index index) ListGrid.getRecordList（）。addAt（ListGridRecord rec，Index index）

However I got the warning message 但是我收到了警告消息

15:48:04.373:MUP3:WARN:Log:ResultSets are readonly. 15：48：04.373：MUP3：WARN：Log：ResultSets是只读的。 This operation (addAt) will be ignored. 此操作（addAt）将被忽略。

I've searched the smartgwt showcase to look for ways to edit a grid , so that new row is added at a specified index, however I wasn't able to find anything suitable. 我搜索了smartgwt展示柜，以寻找编辑网格的方法，以便在指定的索引处添加新行，但是找不到任何合适的行。

I got to know that ResultSets is getting created because I'm using the statement ListGrid.fetchData() Is there any way to solve this issue? 我知道正在创建ResultSets，因为我正在使用语句ListGrid.fetchData（）有什么方法可以解决此问题？ Any suggestion is highly appreciated! 任何建议，高度赞赏！

Muchas Gracias. Muchas Gracias。

Figured it out, quite a weird trick...but works for me... what you need to do is use grid.setRecords(grid.getRecords()); 弄清楚了，这是一个很奇怪的技巧...但是对我有用...您需要做的是使用grid.setRecords（grid.getRecords（））; just before grid.getRecordList().addAt(rec, index); 就在grid.getRecordList（）。addAt（rec，index）;之前 I think doing this makes the ResultSet editable. 我认为这样做可以使ResultSet可编辑。
