Setting Values For Invisible Fields/Properties In DetailsView?
Mar 16, 2011I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." Any ideas on how to accomplish this - either using the method above or another method?The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"

VS 2008 Datagridview Invisible Row
Jul 30, 2009Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.
If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

Setting Currentcell In A Datagridview?
Oct 2, 2011I am writing an program with multiple tabs. I have a class that reads a database and offers that data and other calculated data as a collection (the class is cEngines containing engine rows). I have another class which is a row (item from the list) of the collection (the class is RowData which is an engine). One of the tabs in the program contains a datagridview which is bound to the cEngines class and another tab contains controls bound to the RowData class. Both tabs have a mechanism for selecting/changing the RowData so that both tabs are syncronised. All of this works.
The RowData class has validation - both simple value checking, or more complicated checking based on other items in the class. A validation failure raises an event.

Setting Selected Index On DataGridView Combobox?
Oct 13, 2008I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.

Forms :: Setting DataGridView Cell In Edit Mode

'(or dgvTentander.EditMode = DataGridViewEditMode.EditOnEnter)
dgvMyDGV.CurrentCell = dgvMYDGV.Rows(lastrow).Cells(TeCOL_Quant)
dgvMYDGV.BeginEdit(True)
The code correctly indicates that the cell is selected, and when the page is loaded I can still se the cell selected, but the cursor doesn't appear and nothing happens when I type.
