I updated recently to the latest version of Wisej.
While testing a program by setting the DataSource of a DataGridView firstly to a List of 125 elements then to a List of 0 elements, an error occurred in which it says No Value at Index 0. The Exception is thrown by Wisej.Web.DataGridViewDataConnection.GetValue().
I created an Example in which you can replicate this error quite frequently.
If it helps firstly i Click the Button GenList and then the Button ClearList and the exception is thrown. Even if you try to select any visibile Row, the error stil occurs.
Best of regards,
