Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"

I'm really desperate at this point. I really need to display a graphic in a ReportViewer that shows ONLY the last 5 records added to my table, in the exact order they are in the table. I'm using a MySql database. I tried adding this query in the tableAdapter:
select * from(select * from myTable order by id_auto_increment desc limit 5) as myResult order by id_auto_increment asc
I'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.
View 5 RepliesI want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.
View 1 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I'm writing a program for my job in which we are keeping track of employees usage of food at work. The form in question interacts with an access database to a binded control with labels and textboxes. This form I'm working on is the user view which doesn't allow them to input their username, I have the user name saved to a variable but it will not display when I the add a new record. I tried many things but I'm just getting frustrated.
Is there away to add data to a row that is not displayed on the screen in a textbox for the user to see? There are 3 different "cells" (textboxes) I want to be filled in by other code without the users knowledge.
I'm currently using MSAccess 2010 and Visual Studio.net 2010
I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar
my DataGridView1.Scroll - event
says:
DataGridView1.Columns(0).Displayed=True
DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"
This doesn't make sense to me. Is there another opionion to this Problem, or is this just a small bug?
I use Visual Studio 2008 Pro (Visual Basic) with .NET Framework 3.5.

I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
I am using a DateTimePicker to allow the user to select dates between which, info from a database is selected and displayed in a DataGridView.This works fine exept that the dates selected by the DateTimePicker seem to bring back results in US date format!
If I do a debug.print (DateTime1.text), the date is in UK format i.e 11/05/2009 but when these variables are used in a Select statement, the dates returned seem to be in US format e.g. selecting dates between 01/04/2009 and 7/05/2009 selects dates between 04/01/2009 and 05/07/2009 when the results are displayed in the DataGridView!

View 6 RepliesCan anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
