Big user controls are not available

[Hanna]

When I use grid with big number of rows and just one column and put user control containing some textboxes, checkboxes, buttons e.t.c. in each row, sometimes when control is in the top or in the bottom of form and not wholed placed on the form when i click on the cell it doesn't become active and control is not focused.

Why can I fix this issue?

Hi Hanna,

You need to create a custom celltype. It requires a model class and a renderer class. The model class handles the serialization requirements for the control and creates the renderer class. The renderer class handles the UI requirements of the cell. In that reandere class you need to override the OnDraw method to draw required image in a cell. Right now you can look for the custom cells ( C:\Documents and Settings\haneefm\My Documents\Syncfusion\EssentialStudio\5.1.0.48\Windows\Grid.Windows\Samples\2.0\CustomCellTypes ) in our samples folder. Here is a list of the custom cell types with a minimal description about each.
