Hi ,

I have UltraWinTree with several nodes . On single clicking a node say "first node" , the Subsequent childnodes should open and on double clicking "first node" node again , the nodes should collapes .

So , i used three events and 1 integer to handle this issue . The below code is working fine for the single click to expand the nodes, but when i double click the parentnode to collapse its childnodes continously then for the third or fourth time the nodes collapsing happening for the single click . please help me solve this issue ....

Integer:

int UTAttributesCollapseFlag = 0 ;

Events :

1) private void UTAttributes_AfterCollapse(object sender, NodeEventArgs e)

{

UTAttributesCollapseFlag = 1;

}

2) private void UTAttributes_MouseDoubleClick(object sender, MouseEventArgs e)

{

Point currentPoint = new Point(e.X, e.Y);

UltraTreeNode node = UTAttributes.GetNodeFromPoint(currentPoint);

if (node != null)

{

if (UTAttributesCollapseFlag == 1)

{

node.CollapseAll();

UTAttributesCollapseFlag = 0;

}

3)private void UTAttributes_MouseClick(object sender, MouseEventArgs e)

{

Point currentPoint = new Point(e.X, e.Y);

UltraTreeNode node = UTAttributes.GetNodeFromPoint(currentPoint);

if (node != null)

{

if (node.Expanded == false)

{

if (UTAttributesCollapseFlag == 0 )

{

node.ExpandAll();

}

UTAttributesCollapseFlag = 0;

}
