c# - UserControl in DataGridView -

i made user command contains text box, button , month view. coded dgv column, cell , editing command classes per instructions here: http://msdn.microsoft.com/en-us/library/vstudio/7tas5c80(v=vs.100).aspx

then added references checkbook programme uses info grid view check register. particular column choosing date of transaction. when user clicks little button want month calendar drop down, date may chosen.

the problem when click button seems nil happens. when expand column/cell width & height can see calendar , take date.

i need know how create dgv cell alter size of entire user command 1 time button clicked , go normal after date chosen. happen cell , not create row height alter when have manually.

i need master because other cells require list boxes payee's , categories , calculator.
