We don't have it. What do you need it for?

I need to reply a DGVFilterPopUp into a Wisej project, but a most function aren't present and can't do it.

Example some function that need : ToolStripDropDown, ToolStripControlHost, DataGridView.GetCellDisplayRectangle(collIndex, rowIndex), DataGridView.InvalidateCell(colIndex, rowIndex), also the mthods of DataGridViewCellPaintEventArgs.

Is there any possibility to integrate it in some future?

You can't paint wisej controls like winforms controls, they are server-only components. They are rendered on the client as javascript widgets that create dom elements - like all javascript libraries.

However, Wisej supports custom painting in controls and cells. See the custom painted cell sample and codeproject in /examples.

InvalidateCell is not needed, but if you need an empty method for compatibility reasons, you can extend the DGV class and add a void method.

The ToolStrip set of components is not implemented in Wisej.

There is an introductory paper about migrating WinForms to Wisej here: http://wisej.com/blog/winform-to-wisej-migration-white-paper/
