Use uielement to get the mouse and click ultratedcell & add tooltip to ultratedcell

The infragistic ultragrid control does not provide click cell events, but sometimes we need this event, so we have to write it ourselves:

2. Use the mouseclick event of ultragrid to obtain the cell to be clicked, and then perform the required operations on the cell.
3. MouseclickCode 1 Private   Void Ultrabod=mouseclick ( Object Sender, mouseeventargs E)
   2 {
   3 Uielement mainelement = (Iultracontrolelement) ultrabod1). mainuielement;
   4 Ultrabodcell Cell =   Null ;
   5 // You can define what you want, such as ultrabdcell, ultrabacloud Drow, ultrabdcolumn or columnheader
   6 // Ultraman Drow ROW = NULL;
   7 Uielement = Mainelement. elementfrompoint ( New Point (E. X, E. y ));
   8 While (Element ! =   Null   && Cell =   Null ) // Replace cell with row, column or column header
   9 {
   10 Cell = Preparecell (element );
   11 // Row = preparerow (element );
   12 If (Cell =   Null ) // Replace cell with row, column or column header
   13 Element = Element. parent;
   14 }
   15 If (Cell =   Null )
   16 Return ;
   17 // Here you get the cell you need, then you can do any thing you want
   18 }
4. Preparecell code 1 // Use the same way to get ultratedrow or ultratedcolumn, etc.
   2 Ultrabodcell preparecell (uielement element)
   3 {
   4 // Cast the uielement to the specified element you want
   5 Celluielement cellelement = Element As Celluielement;
   6 If (Cellelement =   Null )
   7 Return   Null ;
   8 // Get the context from the element
   9 Ultrabodcell Cell = Cellelement. getcontext ( Typeof (Ultrabodcell )) As Ultrabodcell;
   10 Return Cell;
   11 }
6. You can use the same method when you need to add tooltip to ultrabodcell, but it is necessary to implement the mousemove and mouseleave event.
