TUniDBTreeGrid - Make selected row expanded
Hi, I know it is possible to fully expand/collapse a UniDBTreeGrid.
What I'm trying to achieve is to only expand the branch that contains the selected record.
Looking at Sencha documentation, it seems there is the "expand" method, so I've tried something like this:
UniDBTreeGrid1.JSInterface.JSCall('expand', ['key id', true]);
Unfortunately, it doesn't work. Any ideas ?
type
THUniDBTreeGrid = class(TUniDBTreeGrid);
procedure TMainForm.UniButton2Click(Sender: TObject);
var
JSStore : TJSObject;
RNo : Integer;
begin
JSStore := (UniDBTreeGrid2 as IUniJSObjects).JSObjects.Objects['store'];
RNo := THUniDBTreeGrid(UniDBTreeGrid2).RecordNo;
with UniDBTreeGrid2.JSInterface do
begin
JSCode('var node='#1'.getNodeById('+IntToStr(RNo)+');', JSStore);
JSCallGlobal('if(node)node.expand', [True]);
end;
end;
Above code works when TreeGrid rows hav
