DataRepeater Glitch when control displays more items than visible #4968

Hi team,

I found an issue present in Wisej.NET 4.0.11 related to

DataRepeater

.

When the control contains more items than the visible area can display, scrolling to the lower items causes a glitch/flicker and it becomes impossible to properly reach the last elements.

I created a small test application where the issue happens with a

DataRepeater

containing 50 items added by code.

I tested the control in two scenarios:

DataRepeater

placed directly on a Form

DataRepeater

encapsulated inside a UserControl

The issue occurs in both cases.

I started testing older Wisej versions and rolled back step by step until version 4.0.7, where the

DataRepeater

behaves correctly and scrolling works as expected.

Environment

• Wisej.NET 4.0.11

• .NET 10

• Visual Studio 2026

I’m attaching sample code and a video showing the issue.

Please let me know if this is already fixed for the next release.

Regards, and thanks.
Paul
