Server Actions in Blazor In-place Editor Component

10 Mar 20235 minutes to read

When sending the In-place Editor component value to a remote server, the PrimaryKey property value is required. Otherwise, the action will not be performed.

If the SaveURL property value is empty, data changes will be handled locally. The OnActionSuccess event will trigger with null as the 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 class SubmitModel
    public string Name { get; set; }
    public string PrimaryKey { get; set; }
    public string Value { get; set; }
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.
