i have use this code to view my database into my datagird[code].....
i want to do is
1. use textbox to search my datagrid column name "EventDate"
2. pass the value of my DateTimePicker(this DateTimePicker is the one i use to add record on "EventDate" column) on the textbox so that when i change the value of my DateTimePicker the textbox will automatically search for saved event on that date, (if no event save on that date then my datagrid must be blank)
I have a form developed using the Dataform wizard (VS 2003). The Form shows Master-Detail data. The details are showen in a Datagrid. The form automatically loads the data in the Form_load event. Now I want to store the data from the datagrid to a datatable. I am using following code to get the details showen in the datagrid into a dataview. The objdsInvoice is the dataset that holds the Invoice And Invoice_Item data.
Dim DV As DataView
Dim tempDT As DataTable
tempDT = objdsInvoice.Tables("INVOICE_ITEM").Copy
[Code].....
Is there any better way to get the datagird values that are currently displayed into a datatable. The datagrid is bound to the details table in the Master-detail type dataset.

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
