Hi Leema,
One way to do this would be to derive a custom cell type like the ones \4.4.0.49\windows\Grid.Windows\Samples\CustomCellTypes\SliderCells\. 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. Then to use your custom cell type in a grid, you need to register this celltype with the grid as shown in this sample.s\Syncfusion\Essential Studio\4.4.0.49\windows\Grid.Windows\Samples\CustomCellTypes.
Here is a minimal sample that show you "How to add the multiple textbox celltype in a cell"
