Is the dynamic data from three columns (SQL) derived from the selected concrete data, according to the list of export string
This is the table above

 public void _f_setTable () 
{

Int row=5;//the number of rows, plus a row headings 
Int col=6;//the number of columns 
For (int c=0; C & lt; Col. C + +) 
{
If (c % 2==0) 
{
CKB=new DataGridViewCheckBoxColumn (); 
CKB. Width=50; 
The switch (c) 
{
Case 0: CKB. Tag=1; break; 
Case 2: CKB. Tag=3; break; 
Case 4: CKB. Tag=4; break; 
} 
DGV_Select. Columns. The Add (CKB); 
} 
The else 
{
The CMB=new DataGridViewComboBoxColumn (); 
CMB. MaxDropDownItems=10; 
CMB. DisplayStyle=DataGridViewComboBoxDisplayStyle. Nothing; 
CMB. Items. The Clear (); 
The switch (c) 
{
Case 1: foreach CMB data in _1 (var). The Items. The Add (data); CMB. Tag=1; break; 
Case 3: foreach CMB data in _2 (var). The Items. The Add (data); CMB. Tag=2; break; 
Case 5: foreach CMB data in _3 (var). The Items. The Add (data); CMB. Tag=3; break; 
} 
DGV_Select. Columns. The Add (CMB); 
} 
}

The most stupid way is traversal, to determine whether checked

Directly through the contents of each column of the DataGrid, if type is the ComboBox, direct access to the current selected value of the ComboBox, create a collection, deposit the ComboBox value to the collection, so you've got a drop-down box selected value,
