Hello all,

I have designed a Gridview chich has a datasource and contains 2 combobox columns.
the first combobox column is for Department, ValueMember=ID and DisplayMember = Name.
The second combobox column is for operations, valuemmember=id and displaymember=operation.

no what happenes, when the gridview is loaded, the department combobox and operations combobox both are filled with all the values,

i want to fill the Operations Combobox Column based on the value of the Department combobox column.

How to achieve this?

Thanks in Advance.

Hello ,

Thank you for writing.

You can subscribe to the CellEditorInitialized event and in the handler, bind the RadDropDownListEditor to whatever data source you want to display. Please check the following documentation article: http://docs.telerik.com/devtools/winforms/gridview/editors/handling-editors'-events.

Additionally, you can check our cascading combo boxes example: http://www.telerik.com/support/kb/winforms/gridview/details/cascading-comboboxes-in-radgridview.

I hope this helps. Should you have further questions please do not hesitate to write back.

Hello Muhammad,

Thank you for writing.

When binding RadGridViewComboBox column it is important to set the ValueMember and DisplayMember properties of the column. They need to be present on your data source object. Detailed information is available here: http://docs.telerik.com/devtools/winforms/gridview/columns/column-types/gridviewcomboboxcolumn.

I hope this helps. Should you have further questions please do not hesitate to write back.
