The following code

the for (int I=0; I & lt; DataGridView1. Columns. The Count; I++)
{
This. DataGridView1. Columns [I] SortMode=DataGridViewColumnSortMode. NotSortable;
}

for (int i=0; I & lt; DataGridView1. Rows. The Count - 1; I++)
{
DataGridView1. ClearSelection ();
String sqlX=string. The Empty;
SqlX +="SELECT the enable the FROM XITEM WHERE LEFT (HOKAN, 2)='BS' and code='" + dataGridView1. Rows [I] Cells [r]." project code "Value. The ToString () +"' ";
String SQL=Program. SqlCommandExecuteScalarReturnString1 (sqlX);
{
If (SQL=="0")
{
DataGridView1. Rows [I]. DefaultCellStyle. BackColor=Color. LightGray;
}
}
}
After click sort, the background color will not retain, so add two lines of code

 for (int I=0; I & lt; DataGridView1. Columns. The Count; I++) 
{
This. DataGridView1. Columns [I] SortMode=DataGridViewColumnSortMode. NotSortable; 
} 

Banned the sorting function, I would now like to open the sorting, after sorting can retain the background color at the same time, how to modify the
