-## Limitations
-
-Column spanning in the ASP.MVC TreeGrid has the following limitations:
-
-* The [updateCell](https://ej2.syncfusion.com/documentation/api/treegrid/index-default#updatecell) method does not support column spanning.
-* Column spanning is not compatible with the following features:
-    1. Virtual scrolling
-    2. Infinite scrolling
-
-> When using column spanning, ensure that the spanned cells do not interfere with TreeGrid operations such as sorting, filtering, or editing, as this may lead to unexpected behavior.

-## Column spanning implementation through API
-
-The Syncfusion TreeGrid provides an API-based approach to horizontally merge cells with identical values in the same row across adjacent columns.
-
-The column spanning feature in the Syncfusion TreeGrid can be enabled using `EnableColumnSpan` property to **true** in the TreeGrid configuration, which significantly enhances readability and delivers a cleaner layout by eliminating repetitive data in columns such as "Status", "Permit Status", "Inspection Status" and "Punch List Status".

 ## Conditional row selection
 
-The TreeGrid supports conditional row selection through the `isRowSelectable` property. This feature enables dynamic business logic to determine which rows can be selected, ensuring that only rows meeting specific conditions are selectable. The `isRowSelectable` property accepts a function that evaluates each row’s data and returns **true** to enable selection or **false** to disable it. The function is executed for the entire data source before rendering, making it suitable for scenarios where selection must be restricted based on criteria.
+The TreeGrid supports conditional row selection through the `isRowSelectable` callback. This allows selection to be controlled by custom business logic, ensuring that only rows meeting specific conditions can be selected. The callback receives each row’s data and returns "true" to allow selection or "false" to prevent it.
+
+Local data: The callback runs once when the TreeGrid initializes and evaluates all records because the full dataset is already available on the client.
+
+Remote data: The callback runs only for the rows displayed on the current page when the TreeGrid first loads. It runs again whenever the grid fetches new data such as during paging, filtering, or sorting to re-evaluate the newly visible rows.

-    The TreeGrid component is designed to handle large datasets while providing flexible checkbox selection with virtualization enabled. The [`ShowCheckbox`](https://help.syncfusion.com/cr/aspnetmvc-js2/Syncfusion.EJ2.TreeGrid.TreeGridColumn.html#Syncfusion_EJ2_TreeGrid_TreeGridColumn_ShowCheckbox) property displays checkboxes in tree column cells, allowing users to select or deselect them directly. This functionality is enabled by setting the property to "**true**". Similarly, the [`EnableVirtualization`](https://help.syncfusion.com/cr/aspnetmvc-js2/Syncfusion.EJ2.TreeGrid.TreeGrid.html#Syncfusion_EJ2_TreeGrid_TreeGrid_EnableVirtualization) property enhances performance by rendering only the visible rows and columns during scrolling. This feature is activated by setting the property to "**true**".
