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

• OnCellRender

OnCellRender

This event fires upon the rendering of the TreeLists columns. It receives an argument of type TreeListCellRenderEventArgs 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 TreeList 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 TreeList cells.

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