I have a problem when trying to show details of XML file by choosing an item from Combobox. I have two XML files, called Employee.XML & Subject.XML. The format is like below
<Employee>
<EmployeeID> </EmployeeID>
<Position> </Position>
[code]....
The Combobox contains Employee and its Position also (eg: A1 - IT professor). When I choose an item in here, its Subject details will automatically show in Textbox (one EmployeeID can have many subjects). I cannot use Combobox.SelectItem because I already set Option Explicit On & Option Strict On. I also make EmployeeID by ascending coming up with its position. How can I show details in TextBox by using Subject.XML? I tried many methods but none can work properly.

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 want to make it so you can type a name into an input box and have it go into your combobox1. Then also have it to where you can load a list of names into your combobox from a text file where the text in the text file would be like this
NAME 1
NAME 2
NAME 3
NAME 4
So it will enter in the combobox1 like that. Also, This is an account maker, So I was wondering how I would make it so after it creates the account it will use the next text, can I just use the "Next" method?

View 5 RepliesI'm creating a dynamic combo box and adding to a form. I'm trying to fill the combo box with a DataSource from an ArrayList and then selecting an item in the combo box based off a value from a property.Problem is, the combo box items don't get bound until after the Form_Load event has finished and the form is visible. So the combo box is empty when I try to set the selected index of the combo box. See code for what I'm doing in detail, and refer to comments in

How to select the right selected index for combo box without a hack (Load timer or something stupid like that)?
I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.

I would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.
