How can I design a datagrid that displays records and when one record is double-clicked, you can edit that record or when the datagrid record is double-clicked you can view the past history of that particular record in detail?

I have a populated datagrid that has some fields that are needed for calculation in my app. In the dataset they are set to Allow DBNull False because I can't have a DBNull in my calculation for obvious reasons. I have found answers to incorrect data entry and blank fields in these critical fields (see code block below), but they only work if some data is entered somewhere in the new record, even if I populate the field with default values other than <DBNull> on adding a new row. If a user doesn't add any information and just tabs through a new record/row or cursors down the app blows up. If they cursor up without entering any data, the blank field procedure for these protected fields engages fine.

View 4 RepliesI am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET. I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes.
For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. [Code]

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
View 2 RepliesI'm not sure about this code. What I wanted to do is to count the number of records in the table that I selected and then add a value of 1 to it to generate a transaction number.
I'm not sure on how to count the number of rows in the reader. So far, this is my code.

View 9 RepliesI am creating an application which will allow users to search parents names and display their childen respectively in a datagrid.I have created a form with two text boxes, a search button and a datagrid. The two text boxes are txtFName.text and txtLName.Text.

I have a problem with a datagridview control, when first loaded with existing data it shows the correct rowcount figure.However, I have a function that when invoked triggers an oledbcommand to clear those records from the database (access) and load new ones from a file (excel/text).The oledbcomands work fine, and the gridview refreshes with the new data fine. However, the rowcount after this refresh is always 0, even with records. What I am doing is creating a module for my app that allows the user to specify the column title and types for a file import - and the procedure will read the header row from a txt/csv or excel file automatically.[code]If I just make edits in the datagridview (as in not invoke the above) the rowcount returns properly.If I close and re-open the form the new data appears, and the rowcount property returns fine also, but I don't really want to have to tell the user to close and re-open it before making any changes.I must be missing something on the refresh or with the datatable or adapter side of things.
