We are using Grid control with OData source (ToODataString() exstension) and OnRead event. When we try to group by some column, it douesn't work. OData query to API is same and OnRead event fires but grid not grouping.
Hello Viktorija,
Indeed, it does not. First, grouping must be implemented with the OnRead handler, you can Follow that as well here: https://feedback.telerik.com/blazor/1458876-onread-should-work-with-grouping (which I believe you have already found). Then, the OData strign must be enhanced to include the groupby statement.
