I recently applied the patch to treegrid because it said there was a bug.

However, I still get an error.

The source is below.

( I tested it on 2 versions, 24.2.3 and 26.2.7, and the same error occurred. )

<SfTreeGrid @ref="obj_Grid_Menu" DataSource="@ds_MenuTree" Height="100%" Width="auto" IdMapping="MenuId" ParentIdMapping="ParentMenuId" TreeColumnIndex="2" AllowPaging="false"

            AllowSorting="false" AllowTextWrap="true" GridLines="GridLine.Both" RowHeight="25">

    <TreeGridEvents OnBatchSave="Grid_UserMenu_Save"

                    CellSelected="CellSelectHandler"

                    TValue="MenuList"></TreeGridEvents>

    <TreeGridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true" ShowConfirmDialog="false"

    <TreeGridSelectionSettings Mode="Syncfusion.Blazor.Grids.SelectionMode.Both"></TreeGridSelectionSettings>

    <TreeGridColumns>

        <TreeGridColumn Field=@nameof(MenuList.PageName) HeaderTextAlign="TextAlign.Center" HeaderText="페이지경로" TextAlign="TextAlign.Left" Width="150" ValidationRules="@(new ValidationRules() { Required = true })">

            <EditTemplate>

                    var menuList = (context as MenuList);

                    <STEF_TextBox @ref="txt_pagenm"

                                  p_enabled="@b_PageNameEnableCheck"

                }

            </EditTemplate>
