How to make the nodes in the lane only stay in the swimlane without exceeding the swimlane width when adjusting the swimlane width ?

Question

When I adjust the width of the swimlane, sometimes the node is separated from the swimlane, such as the situation in the gif below :

It can be seen that when adjusting the length of swimlane, the node is directly excluded from the lane.

Hi
Tealer,Requirement:
Lane children stay in the same lane while adjusting swimlane height.In
SfDiagram, if we placed a child in the lane of a swimlane, then the size of the
lane in the swimlane will not go beyond the size of the child's bounds. So, your
requirement is the basic behavior of the lane. But in the provided .gif, you
are adjusting the height of the lane beyond its children's bounds. So, we suspect
that you have implemented any sample level codes for this behavior, or the node
in the lane is not added as a child for the lane. So, please validate the
implemented codes or modify the already provided sample to reproduce the issue
on our end. This will help us to provide a proper solution for your requirement.Regards,Karkuvel

Hi Tealer,We have validated
the sample. You have used Custom resizing for LPR node alone. So capacitor
remain same in position. Please refer below code snippet,Code snippet:

public class CustoLaneVM : LaneViewModel
  {
      double previousHeight;
      protected override void
  OnPropertyChanged(string name)
      {
          base.OnPropertyChanged(name);
          if (name == "UnitHeight")
          {
              //finding differnce between current lane height and previous
  height.
              double heightDifference = this.UnitHeight - previousHeight;
              // 修复调整的高度过低报错问题
              var skipResizing = (this.Children as LaneChildren).Any(e => (e as INode).UnitHeight +
  heightDifference < (e as INode).MinHeight);
              if (skipResizing)
              {
                  this.UnitHeight = previousHeight;
              }
              else
              {
                  foreach (NodeViewModel node in this.Children as
  LaneChildren)
                  {
                      // 只有搜索到LPR node的时候才会拉伸节点
                      if (node.Key.ToString() == "LPR" || node.Key.ToString()
  == "NO_Block1")
                      {
                          //updating
  height difference to lane's child node and updating OffsetY position
  according to that.
                         
  node.LaneOffsetY += (heightDifference * 0.5);
                         
  node.OffsetY += (heightDifference * 0.5);
                          node.UnitHeight += heightDifference;
                      }
                  }
              }
          }
          previousHeight = this.UnitHeight;
      }
  }
