22 Jul 2021 / 2 minutes to read

By passing In-place Editor component value to the server, the PrimaryKey property value must require, otherwise action not performed for remote data.

If the SaveURL property value is empty, data passing will handled at local and also the OnActionSuccess event will trigger with null as argument value.

The following arguments are passed to the server when the submit actions are performed.

Arguments Explanations
Value For processing edited value, like DB value updating.
PrimaryKey For value mapping to the server, like selecting DB.

Find the following sample server codes for defining models and controller functions to configure processing data.

    public IEnumerable<SubmitModel> UpdateData([FromBody]SubmitModel value)
        // User can process data
        return value;
  • Server actions successfully done, the OnActionSuccess event will be fired with returned server data.
  • If the server is not responding, the OnActionFailure event will be fired with data, but value not updated in the Editor.

In the following sample, the OnActionSuccess event will trigger once the value submitted successfully into the server.
