Is it possible to control only the end of task.
I mean if I don't want the user to modify the start but let him modify the end, is it possible ?
For now I'm just able to set to readOnly the entire task and I want to get control when I let the user modify the task (and which part)

Thx

Hello, Gerald,
There is no a straightforward way to allow changing only the end date for a task item. However, you can handle the ItemChanged event and set back the original task's start. Thus, the user will be allowed to change only the task's end while resizing. I have prepared a sample code snippet for your reference which result is illustrated below:

this.radGanttView1.ItemChanged+=radGanttView1_ItemChanged;
this.radGanttView1.SelectedItemChanged+=radGanttView1_SelectedItemChanged;
private void radGanttView1_SelectedItemChanged(object sender, GanttViewSelectedItemChangedEventArgs e)
{
lastStart = e.Item.Start;
}
DateTime lastStart = DateTime.MinValue;
private void radGanttView1_ItemChanged(object sender, GanttViewItemChangedEventArgs e)
{
if (lastStart!=DateTime.MinValue)
{
this.radGanttView1.ItemChanged-=radGanttView1_ItemChanged;
e.Item.Start = lastStart;
this.radGanttView1.ItemChanged+=radGanttView1_ItemChanged;
}
}I hope this information helps. If you need any further assistance please don't hesitate to contact me.
