Grid Column Events

Updated on Sep 10, 2026

This article explains the events available for the Columns of the Telerik Grid for Blazor.

• OnCellRender

OnCellRender

This event fires upon the rendering of the Grids columns. It receives an argument of type GridCellRenderEventArgs which exposes the following fields:

• Item - an object you can cast to your model class to obtain the current data item.
• Value - an object that contains the value that is rendered in the Grid cell. You can cast it to its data type, for example to a string, DateTime or a number.
• Class - the CSS class that will be applied to the cells. The CSS rules that are set for that class will be visibly rendered on the Grid cells.

Use the OnCellRender event to apply custom format to Grid cells based on certain value

You can also pass lambda expressions to the OnCellRender parameter. Thus, you can provide additional meta data to the OnCellRender handler ( for example column title ) apart from the GridCellRenderEventArgs that it receives by default.
