+## Environment
+
+<table>

+	    <tr>
+	    	<td>Product</td>
+	    	<td>Grid for Blazor</td>
+	    </tr>
+    </tbody>
+</table>
+
+## Description
+
+I am dynamically creating Grid columns in a loop and trying to adjust the column header cell style based on some condition and value from the [column field]({%slug components/grid/columns/bound%}#data-binding). Ideally, I want to implement logic to make this adjustment based on the value in the header cell. I have not been able to achieve this in the HeaderTemplate tag or in any of the cell render events handlers. In other templates, I have access to the @context field, which would make this easy, but that doesn't seem to work in the HeaderTemplate.
+
+## Solution
+
+To dynamically add style to a column's header cell when dynamically creating columns in a loop, use the [HeaderClass parameter]({%slug components/grid/columns/bound%}#appearance) to set a class under a condition and apply different styles depending on the class. For scenarios with numerous and more complex conditions, create a method to determine the appropriate class. 
+
+It's important to note that the [HeaderTemplate]({%slug grid-templates-column-header%}) does not receive a context argument because it is not related to rows and models, as outlined in the [Templates Overview]({%slug components/grid/features/templates%}) of the Telerik UI for Blazor documentation.
