Text for drop down is not being cleared

[Tuan Lam]

I validate the value once the user entered a value or selected a value from the drop down (ie 1 to 100).  If the user enter 9999, I get the callback and I call BeginEdit() and change the value to 100 by calling SetValue().  When the user click on the dropdown again, the value 9999 will show on the text box, how do I clear it? or set the text value to 100.

I fixed the issue by changing ControlText of the control on TableControlCurrentCellShowingDropDown() event.  Maybe you have a better way of doing it.

Hi Tuan,

 

Thank you for your interest in Syncfusion products.

 

As per your last update you are using TableControlCurrentCellShowingDropDown() to customize the DropDownCell. The mentioned way is the better way to customize the dropDownCell. We request you to use CurrentCellShowingDropDown event to customize the cell when dropdown button is pressed.

 

Please let me know if you have further concerns.
