Dear all,

I have a msflexgrid. One of the column is "amount".

I want to know, is there any codes that i can multi-select the rows in the grid by clicking the left button of mouse while the [Ctrl] key is being pressing, then, there is a textbox that display the sum of the "amount" column of the selected row. (The behavior is just like "MS Excel")

Thank you a lot for your help in advance
