+## Add current selection to filter
+
+By default, the CheckBox/Excel filter can only filter the selected items. If filtering is done multiple times on the same column, the previously filtered values in the column will be cleared. Now, it is possible to retain those previous values by using the "Add current selection to filter" option. This checkbox is displayed when data is searched in the search bar of the CheckBox or Excel filter type.
+
+The following image describes the above mentioned behavior.

+## Wildcard and LIKE operator filter
+
+**Wildcard** and **LIKE** filter operators filter value based on the given string pattern, and they apply to string-type columns. But it will work slightly differently.
+
+### Wildcard filtering
+
+The **Wildcard** filter can process one or more search patterns using the “*” symbol, retrieving values matching the specified patterns.
+
+* The **Wildcard** filter option is supported for the DataGrid that has all search options.
+
+Operator |Description
+-----|-----|
+a*b | Everything that starts with “a” and ends with “b”.
+a* | Everything that starts with “a”.
+*b | Everything that ends with “b”.
+a | Everything that has an “a” in it.
+ab* | Everything that has an “a” in it, followed by anything, followed by a “b”, followed by anything.
+
+The following GIF represent a Wildcard operator filtering.
+
+![Blazor DataGrid with Wildcard operator filtering](./images/blazor-datagrid-wildcard-operator-filtering.gif)
+
+### LIKE filtering
+The LIKE filter can process single search patterns using the “%” symbol, retrieving values matching the specified patterns. The following Grid features support LIKE filtering on string-type columns:
+
+* Filter Menu
+* Filter Bar using the [Operator](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Grids.FilterSettings.html#Syncfusion_Blazor_Grids_FilterSettings_Operator) property within the [GridFilterSettings](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Grids.SfGrid-1.html#Syncfusion_Blazor_Grids_SfGrid_1_FilterSettings) configuration.
+* Custom Filter of Excel filter type.
+
+**For example**
+Operator |Description
+-----|-----|
+%ab% | Returns all the value that are contains “ab” character.
+ab% | Returns all the value that are ends with “ab” character.
+%ab | Returns all the value that are starts with “ab” character.

 ## Filtering with case sensitivity
 
 The Syncfusion Blazor Grid provides the flexibility to enable or disable case sensitivity during filtering. This feature is useful when you want to control whether filtering operations should consider the case of characters. It can be achieved by using the [EnableCaseSensitivity](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Grids.GridFilterSettings.html#Syncfusion_Blazor_Grids_GridFilterSettings_EnableCaseSensitivity) property of [GridFilterSettings](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Grids.SfGrid-1.html#Syncfusion_Blazor_Grids_SfGrid_1_FilterSettings) component.
