Hi, I need some assitance in implementing some features from Excel in the datagrid. I'm wondering whether it's possible to copy the content(value) of cell in the xamDataGrid, by dragging from one cell (bottom right corner) and down? The cells included in the drag should then contain the same value as the "original cell". Another feature I'm trying to adapt from Excel, is the header column filtering. Meaning, the header column should display a drop-down of distinct values displayed in the grid's column. The distinct values available for filtering should be displayed in a checkbox list. I also want the grid to display the filtered records, when a checkbox is clicked. The third feature I need to implement is the customized filter option. Where you, in Excel, can select column and set a column's value to be equal to, greater than etc specified filter value. Any clues on how can I implemente these features??!!?? Any help would be greatly appreciated! Thanks!
