Hey there,

Thank you for your feature request! I approved it as a valid request and updated your Telerik points for sharing the idea with the community. If it becomes popular we will raise its priority in the backlog.

Presently, the grid does not support wildcard filtering, but the scenario discussed in this forum thread filter using wildcards may be useful for your scenario.

For example, intercept the ItemCommand when the e.CommandName is Filter, cancel the original command, parse the value using his own CUSTOM logic and then use the FireCommandEvent method to apply multiple filtering logic.

Best regards,
Rumen
