hai friends,
please help me in calculating the attendance percentage and also the total no. of classes
in datagridview using
c# winformsthese attendance values are retrieving from database. the last two fields tot classes and percentage should calculate upto the attendance entered only .
for example : for 30 days we posted attendance only for 10 days then only 10days attendance(tot classes and percentage) only to be calculated.
and absent 'a' or 'A' should indicate with red color. and attendance percentage less than 65 also to be marked red.
