public:
generic <typename TModel>
where TModel : class virtual bool TryUpdateModel(TModel model);public virtual bool TryUpdateModel<TModel> (TModel model) where TModel : class;abstract member TryUpdateModel : 'Model -> bool (requires 'Model : null)
override this.TryUpdateModel : 'Model -> bool (requires 'Model : null)Public Overridable Function TryUpdateModel(Of TModel As Class) (model As TModel) As BooleanType Parameters
- TModel
The type of the model object.
Parameters
- model
- TModel
The model instance to update.
Returns
true if the model instance was updated successfully; otherwise, false.
Remarks
The TryUpdateModel method must be invoked from inside a data-operation method of the control by using the ModelType property for data binding.
