Data Update in Slick Grid
提问by javanes
I have a slickgrid, with about 100 rows. Its data is refreshed in 5 seconds, but it is disturbing at each update the scroll is reset. I have tried to use dataview and dataview.refresh() but this time no change is reflecte to grid.
我有一个 slickgrid，大约有 100 行。它的数据会在 5 秒内刷新，但每次更新都会干扰滚动重置。我曾尝试使用 dataview 和 dataview.refresh() 但这次没有更改反映到网格。
Here what I tried at each refresh:
这是我在每次刷新时尝试的内容：
mapMemoryTableDataView.beginUpdate();
mapMemoryTableDataView.setItems(data);
mapMemoryTableDataView.endUpdate();
mapMemoryTableDataView.refresh();
if(mapMemoryTableGrid == null)
mapMemoryTableGrid = new Slick.Grid("#datatableMap1", mapMemoryTableDataView, columns, options);
mapMemoryTableGrid.updateRow(1)
mapMemoryTableGrid.render()

I have called the following
我打电话给以下
mapMemoryTableDataView.beginUpdate();
mapMemoryTableDataView.setItems(data);
mapMemoryTableDataView.endUpdate();
mapMemoryTableDataView.refresh();
for (var i = 0; i < olist.length; i++) {
mapMemoryTableGrid.updateRow(i)
}
invalidate and refresh did not cure my problem.
无效和刷新并没有解决我的问题。

You should definitely try the invalidatemethod
你一定要试试这个invalidate方法
grid.invalidate();
From personal experience, all you need to do to refresh the grid is to use the invalidatemethod, provided on the grid. This updates everything and also preserves the scroll.
根据个人经验，刷新网格所需要做的就是使用网格上invalidate提供的方法。这会更新所有内容并保留滚动条。
And by refresh, do you mean you are replacing the data, or updating certain rows?
通过刷新，您的意思是要替换数据还是更新某些行？
回答by Grey Wolf
just use
只是使用
gridItems.invalidate();
gridItems.render();
invalidate: mean nead to validate which row you want - in this case: no parameter row id = all row
无效：意味着需要验证您想要的行 - 在这种情况下：无参数行 ID = 所有行

I have called the following code:
我调用了以下代码：
mapMemoryDataView.beginUpdate();
mapMemoryDataView.setItems(pointsRows, "id");
mapMemoryDataView.endUpdate();
mapMemoryDataView.syncGridSelection(pointsGrid, false);
for (var i = 0; i < pointsRows.length; i++) {
mapMemoryTableGrid.updateRow(i);
}
mapMemoryTableGrid.invalidate();
mapMemoryTableGrid.render();

What worked for me was:
对我有用的是：
events[v_current_row_num].field_id = v_new_field_id;
events_grid.updateRowCount();
events_grid.render();
I am using different grid and view names, but the concept revolved around calling updateRowCount and render functions.
我使用了不同的网格和视图名称，但这个概念围绕着调用 updateRowCount 和渲染函数。
