1. Is there a way that Gantt Chart Bar snaps to full Day, instead of Hours, currently as we it from either side it shows changes in Hours, while in our case minimum unit is Days, so we would like it to snap to Days as user moves it from either side

2. Duration Column should also not show value in fractions, we just need to see Rounded Value in Days, not like 5.12485 (See the screen shot attached)

3. What is the First Column ID associated with , and what is it representing, We want to bind it to our own ItemNumber Field (which is in our Model and tranformed to TaskDetail.ItemNumber). Please let us know how to change it to show our ItemNumber values in that column

4. How can we delete Predecessors Relationship from right side, at the moment i only see option to delete it from Predecessors column (Which we do NOT want to show in GanttGrid), If we can Delete the dependency by Right Click , or Tap and Hold, or by double Click on the Dependency line, if there is another way to delete it than please let us know

Please give us more details on this requirement. Whether your requirement is as follows

Behavior:

If Bottom tier’s IntervalType is Days or higher than Days then the task drag or resized to day. Suppose the Bottom Tier’s IntervalType is Hours means then task drag or resized to Hour, like wise for Minutes case too.

Please let us know your concern.

Duration Column should also not show value in fractions, we just need to see Rounded Value in Days, not like 5.12485 (See the screen shot attached)

We have achieved your requirement in sample level to display the rounded values in Duration column.

What is the First Column ID associated with , and what is it representing, We want to bind it to our own ItemNumber Field (which is in our Model and tranformed to TaskDetail.ItemNumber). Please let us know how to change it to show our ItemNumber values in that column

Gantt grid’s first column representing serial number, If you need to display the Task ID means you can customize the VisibleGridColumns Property as like in the below code sample.

Code sample:

[XAML]:

<sfGantt:SfGantt VisibleGridColumns="ID,Name,StartDate,FinishDate,Duration,Resources">

</sfGantt:SfGantt>

How can we delete Predecessors Relationship from right side, at the moment i only see option to delete it from Predecessors column (Which we do NOT want to show in GanttGrid), If we can Delete the dependency by Right Click , or Tap and Hold, or by double Click on the Dependency line, if there is another way to delete it than please let us know
