I am using the DataGrid in which i have added Group Header so when i try to use Virtualization then the data is coming in the grid but when AllowVirtualization="false" then the data is getting dispalyed.
Can anybody tell me why is it happening
For reference below is the Code.
<RadzenDataGrid @ref="grid0" ColumnWidth="200px" LoadData="Grid0LoadData" FilterMode="FilterMode.Simple" AllowFiltering="true" AllowPaging="false" AllowSorting="true" ShowPagingSummary="false" Data="@poDetailCollectionpoDetailCollectionpoDetailCollectionpoDetailCollection" Filte@fi@filterCaseSensitivityterCaseSensitivityCaseSensitivity="@filterCaseSensitfilterCaseSensitfilterCaseSensitfilterCaseSensit@countvity" style=@countheight: calc(1@EditRowoDe@countail0vh - 2@count0px); " Count="@count" TItem@EditRow"@EditRowoDetailR@EditRowoDetailDemo.Models.ErpWise.@EditRowoDetail@EditRow AllowCo@EditRowumnResize=true Ro@OnRenderSelect="@EditRow" Allow@OnRender@OnRenderrtualiz@OnRendertion="true" AllowGrouping="true" Render="@OnRender" GroupRowRender="OnGroupRowRender">
