Is there a way to make one list box dependent on the other based on user input. Here's my situation: A teacher has the ability to enter the name of the student into a listbox via a textbox. The teacher may then select the student from the first student list box and input grades that would go into a grade listbox. If the teacher selects another student from the student list box, the grade listbox would either go empty or show the grades inputed for the other student; all the while retaining all previously recorded grades for other students.

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

View 3 RepliesI would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
