Once this transaction is complete, return to previous page with gridview of all employees. ((language I'm usings is VB))

View 1 RepliesVisual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.
Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.
OK - I have worded this search 40 different ways and I seem to be lost here. Every example I find seems so happy that you can easily drag and drop a datagrid and let the user fill it in -- then they stop! I know how to do everything I am asking through LINQ. That obviously won't translate here. I really should have learned ADO.NET first, then LINQ, but NOoooo... I need to know how to do the following in .NETCF (Windows Mobile 5) using a SQL CE database on the device.
Add a new record and populate some or all of the fields with data I supply. I don't need to add a record to a datagrid - sometimes the user will not even see the record. How do I add a new record -- put data into it and save it? For example: Create a new delivery record, say, and have the program store the date in one field and a number in another field. Search for a record, then update data in it. Again, using LINQ I can do this easily -- I cannot for the life of me find any examples of doing it without it.
I can find lots of examples of populating a grid of databound fields, letting the user make changes then saving it out. I don't need to do that. Say I need to search for the one record that meets a criteria (customerID=10 and orderID=1234), then when (if) that record is found, update a field in it.

View 2 RepliesI would like to be able to programmatically create DataGridTemplateColumns based on my data source. For example, if my source has a date in a particular column I would like to be able to utilize a Datepicker control. I know this is easily accomplished with xaml and a DataGridTemplateColumn at design-time, however, how would I accomplish this at run-time?
Is my best option xamlreader.load or a more traditional route like:
Dim TempCol As Microsoft.Windows.Controls.DataGridTemplateColumn
I have not had any success with the latter.

i am trying to select the value of combobox programatically.. like my application has a form in that they can edit some field.. one of them can have only few values and they cant be edited.. i am populating them in combo box (dropdownlist type) and later ,
Dim cs As String = reader.Item("Category").ToString
ComboBox1.SelectedText = cs
reader is data reader.. when user click id, it loads all values in all text boxes.. then string cs gets value of that record but fails to select it.. in Main UI the Combo box is blank.. when i click drop down item all values are coming(that are defined previously, but i want only 1 values to be displayed that is associated with that id and its present in that drop down)..
I had a DataGridView, and already able to add DataGridViewComboBoxColumn to it. It read data from database StoredProcedure using custom ValueDescriptor class, this is the code for it:
Shared Sub fillComboBoxCellUsingSP(ByVal comboBox As DataGridViewComboBoxColumn, ByVal proc_name As String, ByVal param As Object(), ByVal firstitem As String)
Dim dt As New DataTable
[Code]....
Actually, the line that read comboBox.Value = o is okay. But still, the combo box cell didn't display the value. Just empty. And sometimes, DataError event raised.
If have a textbox that is used to search a datagrid when a user types into it. This seems to be working properly, as the correct row is highlighted when text is entered. However, something isn't quite triggering properly because if I try to get the selected row, using dgSchedule.CurrentCell.RowIndex, it always comes up with whatever the last row that was physically clicked on, rather than the row that is actually highlighted.[code]...
