Pre-fill Data Bindingsource Addnew
Aug 21, 2011
Im using a bindingsource to add new records to my db using bindingsource.addnew()When this is evoked, it seems to automatically increment the recordcount and then blanks out the content of every bound to that tables bindingsource. So that all fields in the new record have to be filled in manually.I would like to be able to pre-fill some of the data in the new record. for instance, when a user adds a new record, have a specific column in the new record automatically populate with the selectedvalue of a combobox.I assume this means I may have to manually code up my own addnew routine, but google has let me down on where to start.

I would like that someone show me (with code) how to add a new row to a bindingsource. The same thing that the bindingNavigator does but writting myself the code.The fields of the table appear in the form using TextBox. When I click the button "ADD NEW", the textBox must be cleaned and must be ready to introduce a new row.

I think I started out with a misunderstanding of what happens with addnew() and canceledit().
I have a strongly typed datasource in memory.
I call bindingsource.AddNew()
Later I find that the record the user was trying to add already exists, so
bindingsource.CancelEdit()
I have not set any properties other than datasource on the bindingsource.
My assumption was that the CancelEdit() would rollback the blank row added by the AddNew(), but I'm getting some odd errors which lead me to believe this is not true.
Could someone verify that CancelEdit() leaves the new row?

in my form_load sub i added a line to enter a new row when the form is loaded by using me.bindingsource.AddNew()Is there anyway i could tell it to only add a new line only if the rows are empty, the table does have a primary key column where its seed is 8000 i dont know if this would make a difference to how you would make it work

In my form.load event, there is a bindingsource.fill event.After the .fill, there are two or three other lines of code that query the newly filled tablemanager. The code gets the number of total records and displays that number on the form.Here is the problem ....When the .fill statement is executed, control reverts to the form and any statement AFTER the .fill event is not executed.I have tried to stick the remaining lines of code into some other form event with little success. These three lines of code only need to run once.Does anyone have a suggestion as to where to stick these lines?

list the steps to fill a combobox using a bindingsource. I dragged a bindingsource onto a form, created a datatable and datatableadapter(correct term?), added a query. I tried but I am missing something, my combobox displays System.Data.

I'm trying add a new row to my databaseTo add a new record a pop up form opens (form2) with a textbox for the user to input their name, they then click the save button and the popup form closes and the main form (form1) is still showing and the added row seems to updated in combobox although it is blank!.This causes a new blank row to be added to the database - the data in the textbox is never saved to the database

Code shown is so far the closest.I do get the NO MATCH message box now although it is a duplicate record. At least I know I am getting somewhere...

I have a DataRepeater that needs to display individual items from a List (Of T). The missing link between them is a BindingSource component.Everything works fine, i.e., the DataRepeater displays list items correctly, and I can add and delete items, even change using the TextBoxes on the DataRepeater.
The problem is that when I change the value of an item in the code, it doesn't get reflected on the DataRepeater. Only when I click a button on the form which executes this code:myBindingSource.ResetBindings(False)

I'm using a bindingsource to bind a dataset to a datagridview. Normally I would use a dataview to sort and filter the data, but since a bindingsource can also do this, I figured I would not need a dataview anymore. But I'm not sure how to get certain data from the filtered source. I know I can get it from the datagridview, but I'm not loading the entire dataset into the datagridview. I guess I could and then just make the columns I don't need be invisible. Or I could go ahead and use a dataview also, but that seems redundant. I was wondering if there is an equivalent to this code to get a specific item from a dataview, but pulling it from the bindingsource:
tbCode.Text = dv.Item(m_recno).Item("CodeNo")
As long as I'm not filtering the data, I can get it from the dataset, but when it's filtered, the indexes won't match.

i am currently working on a database project using Microsoft Access 2007 and VB Express 2008.my problem is, i want to create a searching function in one of my tables; table Coachee. I know that it is possible to search data using bindingsource.filter as i've already succeeded in doing that. The thing is, how do i actually prompt a messagebox saying that the record of the Coachee ID to be searched is not found? [code]

I am trying to get my grid to refresh automatically when the underlying data is updated in the database. Isn't this supposed to work? Or am I missing something? I created a DataTable within my DataSet. Then I created a new form and added a DataGridView (actually I'm using DevExpress' XtraGrid but am trying to get it to work with just the Microsoft controls). I use the menu in the upper left of the grid to set the grid datasource to the datatable in the project data source. This then automatically adds the dataset, BindingSource, and TableAdapter to the form.

I have added a handler in my code for the bindingsource currentchanged event: I have populated a datagridview. AddHandler PeopleBindingSource.CurrentChanged, AddressOf ChangeHandler then on the ChangeHandler Sub I populate an HTML report. However I don't think this is the best event to handle this. I have to datepickers on my forma as well. So say I click on a row in my dgv, that persons report loads. Then I change the start date on my datepicker,
Now i want to click on that row again to refresh the data, but since the currentchanged event doesn't fire the data won't refresh. I have to click on another row then click on the row I want to view in order for the event to fire. which event is best to do this?

Instead of computing the result for each value of variables in combo boxes 1 & 2 separately. I want to compute the result for all the values of variables in both the combo boxes. This whole collection of computations is to be displayed in the Data Grid View, while on top of each column I want combo boxes with the same values as combo box 1 & 2, to optimize the selection from Data Grid View.

I need to insert values into a text-box in a database form, after a 'Add new record' event has been executed
If i code the 'add new' button click event on the binding navigator my code is run first before the record is inserted. This over rights the displayed record then the new record is inserted. Where can i place my code to run after the record has been inserted

I am trying to use a bound datagridview and through the add button on the bindingnavigator adding a new row to the bindingsource and then pass two variables to the datagridview in the new row so they can be associated with the proper ids. I then have a save button for when the end user is done inputting the rest of the data for that record.
The code is below:
Private Sub BindingNavigator1AddItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
AddressesBindingSource.AddNew()
AddressesDataGridView.CurrentRow.Cells("caseNumber").Value = Me.CaseNumberTextBox
AddressesDataGridView.CurrentRow.Cells("interestID").Value = Me.InterestIDTextBox
End Sub
