Use Checkboxs In Datagridview Cells To Change Value?

Jan 14, 2011

I am trying to create a form that will update a database of school tests with checkboxs.Basically, i have a textbox for a student id, a combobox with the subjects in it, and a datagridview with the tests of the selected subject.(There are about ten subects with about ten tests each).What i want to happen is when you put in an id number, it should bring up all the tests the student passed in each subject in the datagridview. So when you select a subject it will load the datagridview with the tests (in a checkbox format) (with the tests he already passed checked) so you can click and add tests and then save it to the db.

Aug 2, 2011

If i have a DGV where i change the color of some of the cells like this...

DataGridView3(0, 1).Style.BackColor = Color.DimGray
DataGridView3(5, 3).Style.BackColor = Color.DimGray
DataGridView3(6, 0).Style.BackColor = Color.DimGray

Comparing Two Cells In A Datagridview?

Apr 29, 2010

I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.

Asp.net - Dynamically Change The Number Of Header Cells In Listview LayoutTemplate

Aug 11, 2011

I'm trying to dynamically create a listview. on reports.aspx user selects a bunch of checkboxes. On the next page, user sees reports.aspx, and should see a table with columns of the checkboxes he selected. My idea was to create a listview, then dynamically change the header row of the LayoutTemplate, then change the select statement depending on which columns selected. This is what I have:

<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate runat="server">
<table runat="server">

[Code]....

Problem is that this doesn't work because i can't put a code block (<%%>) inside the LayoutTemplate. Is there a way in the code behind to edit the LayoutTemplate, or another way to cycle through the Request.Form vars and build the table header row with it?
