Does vb 2010 have a 'REQUIRED" property or control that allow you to make a textbox a "required" field? I googled and saw something about required property in controls in toolbox but somehow I could not find it anywhere in my vb 2010 toolbox. Would it be easier to write it? Does anyone have sample code?

I'm using VB 2008 with .Net 3.5 and I want to check that a combo box has a selected value greater than 0 (default = Nothing Selected) before allowing the user to move off the tab page to another tab page. The Leave event does not allow me to cancel and the Validating event on the tab page does not fire unless the user has at least visited the combo box field.

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

View 4 RepliesI have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

View 2 RepliesHow can i make a control required to put input depending on the radiobuttonlist selection?
Let me try to clarify a bit more. I got 2 radiobuttons, if one gets selected, nothing else has to be done.
But if the otherone gets selected, a textfield must have some input too.
I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.
I have a combobox which reads a directory and displays the file names in the combobox. What I'm trying to do is when a value is selected in the combobox I wish to display this in a label.
I have tried the following
Label1.Text = Combobox1.SelectedValue
But it doesn't seem to work.
My coding to display value in the combobox
With Combobox1
.DisplayMember = "Name"
.ValueMember = "FullName"
[Code]....
I have the first snippet of coding in the Combobox1_SelectedIndexChanged event.
The "FullName" works with textbox1 when i select a value in the combobox but I want to display the "Name" in label1.text
I am creating an application install program, but one of the main things i cannot get working is the combobox, this is a drop down list of all my applications that i have put in there. I was wondering if there was a way you could tell the combobox to look at a directory or share and list the names of files within it? So, for example i could place 5 programs inside a share or directory then when i run the program and the click the drop down combo the 5 programs are listed and then i can click and install this program. Also then if i add/remove any programs it also removes it from the combo list.

I am developing a new project for my daily office use using access database with vb 2005.
In this project I have one bounded datagridview and it is ready to use.
I want to alter a particular field value in the datagridview regularly. so whenever I click the rowheader that particular field should be editable with a combobox with some value, after selection of the value and leaving that particular cell it should be updated with the appropriate record in the database.
