1.How can i make all the rows in the grid to be selected by clicking on the upper left header (Intersect

ion of row and column header).

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {   
            e.Layout.Override.RowSelectorHeaderStyle = RowSelectorHeaderStyle.SeparateElement;
        }

        private void ultraGrid1_MouseDown(object sender, MouseEventArgs e)
        {
            UltraGrid grid = (UltraGrid)sender;
            RowSelectorHeaderUIElement rowSelectorHeaderUIElement = grid.DisplayLayout.UIElement.LastElementEntered as RowSelectorHeaderUIElement;
            if (rowSelectorHeaderUIElement != null)
            {
                this.ultraGrid1.Selected.Rows.AddRange(this.ultraGrid1.Rows.GetFilteredInNonGroupByRows());
            }
        }

You might also want to look at this KB article which describes different ways of selecting all rows in the grid.

2.How can i place the icons on the cells as in HolidayList column.(When user clicks on the icon i

need to show the calender at the right body page).

You could do this in a number of ways. I'd probably use an UltraTextEditor with a button in the ButtonsRight collection and attach it to the column via the EditorControl property.

2.Is there any replacement for Microsoft Property Grid in Infragistics component.

The closest thing would be the UltraWinTree. There's a sample included with NetAdvantage that demonstrates using the tree as a property grid.
