Setting A Default "SelectedIndex" When Adding A New Record Refuses To Work?
Jul 16, 2006
I have a typical databound Form with a bound ComboBox bound on the form Load event.I have a typical BindingSource and BindingNavigator Control with an "AddNew" button.When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting...
mycombo.selectedindex = 0
I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to -1 As an experiment I added a button to the form and on the click event pasted "mycombo.selectedindex = 1".I added a newrecord then clicked this button and the combobox updated as expected. But I wont this to work as I'm adding a record!Is there a particular event where I should set mycombo.selectedindex = 1 apart from the two I mentioned?

adding to the binding source then setting the combobox to selectedIndex of newly added row is not working.the new row is in there but it does not set the selectedIndex to the specified index. but if I run the code a second time it selects it.what can i do to make sure the combo uses the specified index?
Dim drv As DataRowView = CType(Dispatch.M8CustomersBindingSource.AddNew(), DataRowView)
drv("custID") = "999999"
drv("CustomerName") = "Select Customer"

I have a DataGridViewComboBoxColumn that I allow the user to add new items to by typing in the ComboBox and hitting the 'Enter' key. That triggers CellValidating and I do the adding there by the following:
cmbColumn.Items.Add(e.FormattedValue)
All this works well, except that it leaves the DataGridViewComboBoxColumn blank. How can I set the DataGridViewComboBoxColumn to display the e.FormattedValue?

I have ComboBoxes on my form that have two functions.Editable / AutoComplete - SuggestAppend Non Editable. If the ComboBox is not editable, I am looking to set the SelectedIndex = 0 but not to set any SelectedIndex if the ComboBox is editable/AutoComplete. I have the following in my code and all the values are right; however, all ComboBoxes are showing a default item regardless. Any ideas? [Code]

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))

I am trying to make my program assign "0" to an empty textbox when the user hits START. I'm trying to use a "for each" loop, but with no success so far. I've tried a bunch of different things, but here is the closest i've gotten (all the items added to the collection are textboxes):
Code
Private Sub TESTSTART_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TESTSTARTButton.Click
Dim value_collection As New Collection
[Code]....
when i click the start button, i get a "mismatched type error" ..

I programatically / runtime created combobox and bind it to a datasource but can not set its default value. Since I am using the Handler of SelectedValueChanged, this is causing the program to mis-fire. Here is the code I am using.
Public WithEvents T_combo as ComboBox
'dictionary holds data to use in other parts of program
Dim T_Dict As New Dictionary(Of String, String)

Is the default format of ToString dependent on anything server related? Here's the issue: I'm testing and have tested an application on my local machine and ToString(), by default, is returning in a format of "MM/dd/yyyy hh:mm:ss tt", however on our server it appears to be returning as "dd/MM/yyyy hh:mm:ss tt" which the consuming application is not expecting and causing errors.

I am trying to set the "ColumnHeadersDefaultCellStyle" property to the "GoudyHvyface BT" font and it will not change from the default. I am using Visual Basic 2008.
I have set the property properly with no success.
I have tried to set the property in code, using the suggestions in the MSDN and it kept throwing errors.

So I made a little program, and when I run it on my computer the Date format displays as DD/MM/YYYY, but when I run it on some other computers it displays as MM/DD/YYYY. Is there anyway to set the default incoming Date format? Or do I just have to be very careful about how I get/set parts of dates?

I want to modify the default Object text size for all objects I place on my form. When I am teaching, it is hard to see the text on the objects. I have changed the code area to 16 pt, but I have not seen how to modify the default font size of the object. They all are 8.8 pt.

I am creating a customised version of the ListView control and there are several of the properties that a ListView has that I would like to be set to a different value to the ListView default when a user goes to use my user control.
From what I've found there seems to be a number of people suggesting just set them in the constructor, but to the best of my knowledge that would just mean that the user would not be able to change the properties in the PropertyGrid in the VS IDE.I assume this is probably something extremely simple that I have overlooked.

I have a label printer with the driver loaded with the settings in the driver set I can print the exact label that I want, I have the problem that I need to set the default settings in the driver when the software starts. there are 6 of these printers and the only problem we have found is that different operators like to change the settings.
What I need to do is to set the following commands in the driver so each time the system is started (daily) it loads the settings and works properly.
I need to set
Custom Commands Text, Start, Parsed Text
In the Advanced Setup, turn on use printer settings
Other settings would be usfull but as I cannot set these I do not think I will be able to set others.
I can currently set some of the commands eg,
DefaultPageSettings.PrinterSettings.Copies=2

For some reason when I place a button on a form and type some text, the text is too big for the button. Descenders are not shown (i.e., the bottoms of g's, p's, q's, etc.). Does anyone know how to modify the default settings of the button, such as the height or font size? Obviously I can change these properties after I place the button on the form, but this gets old. My default font size is 7.8pt San Serif. If possible I would like to increase the default button height and the font size (I like to use bigger text for teaching in class so those in the back of the room can see).

Can you set the default button of a panel with a button that is not in that panel but in another content placeholder within a master page? I have tried this but I get the following error:
The DefaultButton of 'pnlTmp' must be the ID of a control of type IButtonControl.
I have also tried setting the panels DefaultButton this way :
pnlTmp.DefaultButton = btnContinue.UniqueID
This gave me the same error.

i finally designed my own custom notepad. pretty much all the features, minus a few, and plus a few.. i like the new features. ;o)

I have a page that is based on a Master Page. The page has AJAX contolled tabs and on one tab I have 2 panels, each with 1 button. Only 1 panel is visible at a time. I am trying to get the button on the visible panel to be the DefaultButton so that when Enter is pressed the click event is fired off. The issue that I am having is that I get this error no matter what I try: The DefaultButton of 'form1' must be the ID of a control of type IButtonControl.I have tried setting the Default Button property of the panel to the buttons client id and to its unique id.

Just started using the Windows Browser in one of my forms so the user can select a photo they need to load. This was surprisingly easy (This seems to be the norm in Basic, if you think it will be hard it isn't and visa versa). What I am struggling with is how to set the default location to 'Computer' rather than a disk letter and directory name. The photo is most likely to be on a card reader or Memory stick so the drive letter is likely to change.
I am guessing the command will be:
OpenFileDialog1.InitialDirectory = ???????

I have a WebBrowser control in a VB.NET WinForms app. I am able to set the default printer from code and print without prompting the user. However, there is also a print button that shows the PrintDialog. If this action is done first the page will print.Then if I try to programmatically print later (again setting the default printer to some other printer) the it will print to the last printer selected in the PrintDialog box even though I am resetting the default and see the default printer being changed in Windows.It works fine unless ShowPrintDialog has a printer chosen first. Once that occurs it seems to always use that printer no matter what I do.

If strPrinter.Contains("My Printer") Then
