-- Update --
I found the issue. When I put this command inside the treegrid, EnableCollapseAll = "true" , it caused the undesired behavior. If I remove this, the grid works as expected.


--- Original ---
When doing a search which results in the parent and a child both containing the search criteria, the search results show two rows each showing only the parent. If you click on the expand arrow, the child never appears. For example:

Parent: {Id=1, Name=Charlie, Code=CHAR}
Child:  {Id=2, ParentId=1, Name=Charlie 1, Code=C1}

Search Criteria = char
Tested with  FilterHierarchyMode.Parent, Both, Child, and None.

    < EjsTreeGrid ID="TreeGrid" @ref="TreeGrid" DataSource="@TreeData" IdMapping="OrgUnitId" ParentIdMapping="ParentOrgUnitId" TreeColumnIndex="1"
                 AllowPaging="true" AllowExcelExport="true" AllowFiltering="true" AllowMultiSorting="true" AllowPdfExport="true"
                 AllowReordering="true" AllowResizing="true" AllowRowDragAndDrop="true" AllowSorting="true"
                 EnableAltRow="true" EnableCollapseAll="true" EnableHover="true" ShowColumnMenu="true"
                 Toolbar="@(new List() { "Search" })">

        < TreeGridSearchSettings Operator="Operator.Contains" Fields="@(new string[] { "Code", "Name", "LegalName" })"  HierarchyMode="FilterHierarchyMode.Both">

        < TreeGridEvents TValue="Node" RowSelected="RowSelectHandler" OnRecordDoubleClick="DoubleClicked">
        < TreeGridSelectionSettings Type="Syncfusion.EJ2.Blazor.Grids.SelectionType.Single" Mode="Syncfusion.EJ2.Blazor.Grids.SelectionMode.Row">
< /TreeGridSelectionSettings>
        < TreeGridPageSettings PageSizeMode="PageSizeMode.Root" PageSize="50">
        < TreeGridEditSettings AllowAdding="false" AllowEditing="false" AllowDeleting="false" Mode="Syncfusion.EJ2.Blazor.TreeGrid.EditMode.Row">
< /TreeGridEditSettings>
        < TreeGridFilterSettings Type="Syncfusion.EJ2.Blazor.TreeGrid.FilterType.Menu">
        < TreeGridColumns>
            < TreeGridColumn Field="Code" HeaderText="Code" Width="20">
            < TreeGridColumn Field="Name" HeaderText="Name" Width="40">
            < TreeGridColumn Field="LegalName" HeaderText="Legal Name" Width="40">
            < TreeGridColumn Field="ExternalCode" HeaderText="Ext. Code" Width="20">
        < /TreeGridColumns>
    < /EjsTreeGrid>

This shows the search applied. Search is on Code, Name, and Legal Name fields.  



This shows the tree grid without a search applied:

Hi Scott, 

Thanks for using Syncfusion products. 

Query: When doing a search which results in the parent and a child both containing the search criteria, the search results show two rows each showing only the parent. 
 
We were also able to reproduce the mentioned issue on our side. We have confirmed that the mentioned issue is a bug and have logged the bug report for the same. Thank you for taking the time to report this issue “Searching is not working properly if EnableCollapseAll is set as true” and helping us improve our product. Fix for the issue will be included in our Next Bi-Weekly Nuget release which is expected to be rolled out on or before 5th  February 2020.
