Hi Soumyajit ,
Thank you for contacting Syncfusion support.
We have analyzed your query. We cannot access GetVisualContainer() helper method in product version 12.3 since its available only from version 12.4 . So, we request you to upgrade your product version, otherwise you can get VisualContainer by using Reflection because in 12.3 we have VisualContainer is internal. Please refer the below code example for getting VisualContainer using reflection:
|VisualContainer visualContainer = this.DataGrid.GetType().GetProperty("VisualContainer",BindingFlags.NonPublic | BindingFlags.Instance).GetValue(this.DataGrid) as VisualContainer;|
We have modified a sample byusing Reflection and attached the sample in the following location, please refer it :
Please let us know if you require further assistance on this .
