@zhussain @Nabil Siddiqui @SHEIKH ITRAT QURESHI, Update About Student Data Form Entry: Yesterday I have installed the SMS project into my laptop and also correct the crystal report issues by installing crystal report software.
After that, I have connected Ms. Samina on Phone and discussed her concern to understand the problem. What I observed/Understand that she was confused about the PINK highlighted list of new admission student record as he said whenever she had completed the form entry the record turn into white which reflects that the particular student form has been entered.
After reading the SMS code in (AdmissionList.aspx) which display the list of new admissions I have come to know that, the PINK highlighted records are those record in which ADMDate field (from tblStudents) is null which mean that this record is not yet updated through data form.
The issue which is finally highlight that in the new fee receving procedure whenever the new admission fee challan received it will also update the tblStudents with all related/available data including the ADMDate. Since this process in action from last 5-6 months, branches were observe all such record into their Admission list in WHITE color which as per previous practice indicate that these records have been entered from student data form.
Now from the Last taken SMS backup database I have found that all those new admissions records into tblstudents have been updated by replacing the admdate field with NULL to display the branches admission list into PINK color. 
if it was updated as per your @zhussain instructions then this is the reason Ms. Samina Mahtab view her admission list in PINK color again, because beside the new admission process she was also updated the admission forms at her end to complete the form data entry work and these (ADMDate) replace with NULL also which cause the confusion to Ms. Samina Mehtab.
I again send her an Email and get her on board to start her data entry work again and I am also do the same on the test server beside her to observe the complete process of Form data entry.
