If you cast your cell into a DataGridViewCheckBoxCell then you should be able to use the checked property to see if checked

cell1.checked == true

You're setting the false and true values to "0" and "1", respectively. But converting strings to boolean like you're attempting to do in the foreach loop will throw a FormatException.

Converting the numbers 0 and 1 to booleans, on the other hand, will return false and true.

DataGridViewCheckBoxColumn GvCheckBox = new DataGridViewCheckBoxColumn();

GvCheckBox.FalseValue = 0;  // replaced "0"
GvCheckBox.TrueValue = 1;   // replaced "1"

you can use :

 if (Convert.ToBoolean(this.GvViewPendingCheque.Rows[0].Cells[0].Value) == true)
        ...

but i'm nut sure if this is a correct way to access a cell in your data grid view. easier way to access a cell [row, column]:

if (Convert.ToBoolean(this.GvViewPendingCheque[0,0].Value) == true)
