I don't understand what's going on here I published my project, and when I create new records and save them, everything gets saved and shows up each time I run the program.I open the database in SQL Server and none of the tables have the new data, but it still shows up when I run the program each time.

I have a form that has around 4 txtboxes. Data is inserted into these boxes and then a "Save" Button is pressed. I have a GridView added to my form and want to view the entries. The issue I am having is that when I click the save button the data doesn't show up in the DataGridView until I close the application and then re open it.

I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work. I've tried adding a dgCustomer.show statement, The form that calls the user control has no codebehind code, and throws no errors.

I've run into a problem that I'm at a loss to understand and/or work around. I'm working on a settings page that updates an XML file. The page has an XmlDataSource with a transform file (to filter and sort the values) and a DataList that is populated from the XmlDataSource. A user can enter a new group name into a text box and click a button to submit the form. When this happens, the new value is successfully added to the XML file.

View 2 RepliesAlright it's been awhile since I messed with this project, so here goes. It's an appointment scheduler and everything works except two things: I can't edit existing appointments and it only records the current time, not the timeslot I click on.
If I try to edit an existing appointment it doesn't get the row data, just shows me blank text boxes. I assume I have to have those text boxes read the info from the database, but I don't know how to do that.
This is how it looks:
So, you double click a time slot and it looks like the second window. You can right click on an existing appointment to edit it, but when you do that all the text boxes remain blank like you're inserting a new one.
What code would I use to read whatever row's data I am trying to edit and insert it back into the boxes?
Here is the code I use to add new rows to the DB:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
