I added a datagridview box to my form from the tools menue. I added some columns and would like to place a save button that allows users to save the data they put in those columns. The datagridview is not bound to a database, it is only being used for design reasons and a database is not necessary. What code can I use in the button to save the changes?

I have a login form that consists of 2 text boxes: txtUser, txtPass. Now these are not bound to any data table & I don't what them to be bound. When a new user enters his user name & password, I want to add these on a data table that has two columns: User, Pass. Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?
View 1 RepliesI have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.
View 7 RepliesHow to update data in a table bound to a datagridview? Using Visual Basic 8.
View 1 RepliesI have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:
ds.Tables(0).Rows(dgCourseList.SelectedRows(0).Index).Delete()
My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.
Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?
I would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.

View 3 RepliesI have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [Code]
View 2 RepliesI have a form which is bound to a table that includes information about properties (real estate). Each property can have a number of inspections. These inspections are included in a separate table.
I want to use the form to show the property information and a data repeater to show all the inspections for that property.I can't seem to get the data repeater to bind to the inspection table and pull only those records related to the property information table. In fact, the data repeater shows nothing.
I can get a data repeater to show all the records in the inspection table when I put the control on its own form, for testing purposes.
I'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
Here's what I have:
' Declare
Private addedRowIndex As Integer
Code:
Dim newMessagesRow As ArcadeDataSet.messagesRow
newMessagesRow = ArcadeDataSet.messages.NewmessagesRow
newMessagesRow.movie_title = "Added Programmatically"

I have written some functions that I have in a module. In one of the functions I would like to update a table that is in a dataset. I would like to do this with this function and not from a form class where the table could be bound. I need to call the function from various places in the application.
View 3 RepliesVisual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table. Is there something I can do or put in one of the events that would identify this as a change.

View 1 RepliesI have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.

I want to allow blanks in BOUND textboxes that are bound to int and money columns.
It's not letting me - apparently it knows to force digits...
Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.
