Thanks and Regards

I'm not sure if there is any way to get the delay using UltraToolTipManager/UltraToolTipInfo. One alternative would be to start a timer in MouseEnterElement, then show the tooltip when the timer expires.
I've made a thread about something related to this. How will you use the InitialDelay property in this code? ShowToolTip will not use the delay, it will just show the tooltip right away....
The following code sample demonstrates how to show a tooltip for an UltraListViewColumnHeaderUIElement using the UltraToolTipManager:
private UltraToolTipManager toolTipManager = null;private UltraToolTipInfo toolTipInfo = null;
private void Form1_Load(object sender, EventArgs e){ this.listView.MainColumn.Text = "Name"; this.listView.View = UltraListViewStyle.Details;
int itemCount = 100; UltraListViewItem[ items = new UltraListViewItem[itemCount]; for ( int i = 0; i < itemCount; i ++ ) { items = new UltraListViewItem(); items.Value = string.Format("Item {0}", i); }
this.listView.Items.AddRange( items );
this.listView.MouseEnterElement += new UIElementEventHandler(this.listView_MouseEnterElement); this.listView.MouseLeaveElement += new UIElementEventHandler(this.listView_MouseLeaveElement);
}
private void listView_MouseEnterElement(object sender, UIElementEventArgs e){ UltraListView listView = sender as UltraListView;
// Create the UltraToolTipInfo if it is null if ( this.toolTipInfo == null ) { this.toolTipInfo = new UltraToolTipInfo(); this.toolTipInfo.ToolTipTitle = "UltraListView"; } // Create the UltraToolTipManager if it is null, and associate // it with the UltraListView and this form if ( this.toolTipManager == null ) { this.toolTipManager = new UltraToolTipManager(this.components); this.toolTipManager.ContainingControl = this; this.toolTipManager.SetUltraToolTip( listView, this.toolTipInfo ); }
// If the cursor is positioned over an UltraListViewColumnHeaderUIElement... UltraListViewColumnHeaderUIElement headerElement = e.Element as UltraListViewColumnHeaderUIElement; if ( headerElement != null ) { // Get the column; check for null because it will be if this is // the "dummy" column header, i.e., the one that is shown when // the actual columns don't fill the entire width of the control. UltraListViewColumnBase column = headerElement.Column; if ( column != null ) { // Set the ToolTipText and show the tooltip this.toolTipInfo.ToolTipText = column.TextResolved;
Rectangle toolTipRect = listView.RectangleToScreen(headerElement.Rect); Point toolTipLocation = new Point( toolTipRect.Right, toolTipRect.Top ); this.toolTipManager.ShowToolTip( this.listView, toolTipLocation ); } }}
private void listView_MouseLeaveElement(object sender, UIElementEventArgs e){ // Hide the tooltip when the cursor exits the bounds of an UltraListViewColumnHeaderUIElement if ( e.Element is UltraListViewColumnHeaderUIElement && this.toolTipManager != null ) this.toolTipManager.HideToolTip();}
