how to set some GanttControl.TaskAttribute as read-only

[joshua liaud]

Hello,

This is my problem : 

In all of these attributes (below) I would like to set as Read-Only only the TaskNameMapping if it's possible ?

TaskIdMapping="Rank"

TaskNameMapping="Name" => ReadOnly:"true"

StartDateMapping="StartDate"

FinishDateMapping="EndDateGantt"

DurationMapping="RealisationTime"

ProgressMapping="Progress"

CostMapping="AmountHT"

Thanks!

Hi Tibor, 

We have achieved your requirement to disable the parent task edit in Gantt grid by using QueryCellInfo event in the sample level. Please find the demo sample from the following location.
