How do I know the data source of a series.

[SDG]

Yesterday I have posted a question for this.
I found that the property Xvalue.Valuesource and Yvalue.Value source gives the datasource. but this property works only when the values are assigned at designtime.
How do I know the valuesource if the Dataset is assigned in the runtime?

It doesn't matter if it's set at design or at runtime. I guess one way to determine is series datasource is dataset is to use the following code:

Code: Select all

  if Series1.DataSource is TDataSet then ShowMessage('Dataset descendant');
