Is it possible to add a comstomized comboBox into GridDataBoundGrid?

For windows datagridview, we can create classes inherited from DataGridViewTextBoxCell and DataGridViewColumn, then add the derived DataGridViewColumn class into Columns property of DataGridView. Just wondering if we can do something simular for syncfusion control?

See the discussion in the grid's User Guide on deriving Cell Controls.


It is under the Basic Concepts section.

You can also see many examples of custom cells in samples we ship. Look in this folder (or whereever you installed the samples).

Thanks for your reply.

Examples in local machine are designed for GridControl. And I'm looking for someting can be used in GridDataBoundGrid.

I've created my own CellModel and CellRenderer to display a customized comboBox. Now I'm wondering how to plug it into the GridDataboundGrid. There're no CellModels property for GridDataBoundGrid. I've also tried to handle PrepareViewStyleInfo event. But CellMode of GridStyleInfo is readonly, so I cannot assign my model to it.

Is there another way to customise the control for GridDataBoundGrid?

Hi Keping,

Thanks for your interest in Syncfusion Products.

Custom cell type can be created in GridDataBoundGrid. The sample in the below link uses the custom cell type ''DropDownUserCell''. It uses DropDownUserControl as a custom cell. It does so by being derived from GridDropDownCellRenderer and GridDropDownCellModel.


Please let me know if any concerns.

Good example!!! Thanks mate.

Since I've created the model and renderer for grid control, I can simply assign it to:
1. Model.CellModels
2. Binder.InternalColumns[0].StyleInfo.CellType

Easy... :)

Would you please update those information into the help file for next release. Cause I found that the help file was not good enough to understand how to use the some of controls. Most of the time, I have to search the forum or post question. But you guys provided really good customer service and repsonse very quickly... Much appreciated.
