We use the Kendo Grid with a DataSource connected to an OData service. We also use the OOB Kendo Grid functionality to hide columns in the UI (column.hidden = true). Through testing we found out that the Kendo grid does not use the OData option of selecting specific columns for retrieval. The grid will request all columns for a table, which leads to overhead in the amount of data sent from the server to the client. We sometimes have tables with 50 columns, for which only 10 columns are shown.
Hello,
Requesting specific columns is only possible for OData, thus integrating such functionality is kind of a corner case. For now we recommend using the parameterMap function to modify the query and add only the specific columns that are desired.
