Hi Team,


I am new to EJS and have added EJS grid in my project and works fine. when i give AllowGrouping True for record (less than 800) grouping works fine. 

When the record count is large (say 1500)  and when try to drag  and drop the column in the header for grouping the page got hanged.

......

col.Field("ILOOKUP_AKS").HeaderText("ILOOKUP AKS").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Left).Add();

).AllowMultiSorting(true).PageSettings(page => page.PageSizes(new List<object>() { 5, 10,15,20,25,30 })).AllowTextWrap(true).AllowPaging(false).AllowExcelExport(true).AllowResizing(true).Height("400").AllowExcelExport().ToolbarClick("toolbarClick").Toolbar(new List<string>() { "ExcelExport" }).FilterSettings(filter => { filter.Type(Syncfusion.EJ2.Grids.FilterType.Excel); }).AllowGrouping(true).FrozenColumns(3).Render()

Hi Nivas, 

Thanks for contacting Syncfusion support. 

We have validated the provided information. In your sample, you are enable both grouping and frozen columns in Grid. We have limitations in frozen rows and columns feature in Grid. Grouping is one of the limitation so we suggest you to use either frozen rows and columns or grouping in your sample. Please refer the help documentation link for more information.  

  1. Grouping
  2. Row Template
  3. Detail Template
  4. Hierarchy Grid


Regards, 
Thavasianand S.

Hi Nivas, 

Thanks for your update. 

Query : made frozen , paging to false and still getting hang when record is large. 

By default, we are rendering Grid based on the cells. While using large amount of data (For example 1,500 * 5) it may take time to render the cells(7,500) to DOM element so that it cause the reported problem. 

We suggest you to load the data on demand basis and you can do so by enabling the paging for the better performance (while using large amount of data)
