View 1 Repliesim having problems with the project i was assign, so im supposed to make like a retail store POS, where i look for the articule and add how much did they take and the price.
So this is the main window is attached to this post [TEX]MAIN.JPG[/TEX], so my main problem is that im supposed to copy all the info from the top combobox and textboxes to the datagrid and so the first item it does enter it ok(well thats what i think) and when i try to enter the second item it just refresh the first item So what im expecting is that the datagrid makes several entries so that after that i can transfer all of that to a database registering the sale.
So this is the code of the button that inserts the article to the datagrid
Private Sub ACEPTAR_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ACEPTAR.Click
TEST1.Text = "Aceptada"

I finally got my last project done and Im updating it and making it more efficient. So instead of DGV to list users what Ive done is using a combobox to list the agents names in the database. I got that part done and I have that table as the datasource for the combox and that part works fine. However Im wanting when they select the Name from the combox it gets the values from the columns and displays them in the appropiate area. Ive tried like SELECT PhoneID FROM agents WHERE Agentname =" & comboname.text, but I cant get it to work that way.

I am working on a desktop application, and in my application i am using combobox in 2 ways:
1. directly on the form, and
2. as a column in the grid.
This is how i have to used it in my application: whenever i am writing anything or selecting anything in my combobox it should display a floating panal containing a grid having some extra columns which help me in selcting any value in combobox.

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 am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.
I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.

I am making a custom ComboBox, inherited from Winforms' standard ComboBox. For my custom ComboBox, I set DrawMode to OwnerDrawFixed and DropDownStyle to DropDownList. Then I write my own OnDrawItem method. But I ended up like this:
How do I make my Custom ComboBox to look like the Standard one?
Update 1: ButtonRenderer After searching all around, I found the ButtonRenderer class. It provides a DrawButton static/shared method which -- as the name implies -- draws the proper 3D button. I'm experimenting with it now.
Update 2: What overwrites my control?I tried using the Graphics properties of various objects I can think of, but I always fail. Finally, I tried the Graphics of the form, and apparently something is overwriting my button.
Here's the code:
Protected Overrides Sub OnDrawItem(ByVal e As System.Windows.Forms.DrawItemEventArgs)
Dim TextToDraw As String = _DefaultText
__Brush_Window.Color = Color.FromKnownColor(KnownColor.Window)

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.
I think my question is discriptive, or as Microsoft in the Documentation for Data Grid the question is, How do I have a combo box column display a sub set of data based upon the value of a different combo box column?

View 5 RepliesI'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.
View 11 Replieshave build some code which goes through the datasource finding records on what a user types, basically if the user types 'P' in the combobox it finds all records from FieldName with 'P' and if you type 'Portugal' it finds all records from the FieldName with 'Portugal, it all narrows down the search list say if there are to entries which match 'Portugal' the combox would only have to items in. The problem i am have is that when i bound the datasource back to the combobox every letter you type stays at Postion 0 of the combobox and doesn't move to the end of the letter as normally the combo works, does any one now how to get arround this problem.
