Why would this code - that loads lots of VENDORS into this dataset - only show "1 of (1)" on the binding navigator?
VendorBS is the BINDING SOURCE.
Private Sub vendorLoad()
Dim connectString As String = "Server=fps-lap-szsqlexpress; Initial Catalog=Casefiles; Integrated Security=SSPI"

i want to control the functionality of moving the records thru binding navigator in vb.net
for example, on click of next button in navigator, i want to check some condition, if condition is true then move to next record otherwise don't move.
is there any way that i could link/bind multiple binding source to only one binding source navigator?

This is my first time using a Binding Navigator in a program that I am creating.I have the base of the binding navigator working, data source has been connected (fields etc.). What I need to know now is how I can create a new entry by clicking the '+' button on the navigator, and the new entry appear in the Access database
View 3 Repliesi have a created a project that enables the user to choose any access database and presents the different tables on a treeview... after that the user is able to drag and drop fields on to another form and automatically controls (text boxes, combo boxes etc.)are created with their respective data bindings... it also creates a binding navigator.... my problem is that i cannot get to add or delete records from the database using the navigator... when i add and try to save it i get an error "Update requires a valid InsertCommand when passed DataRow Collection with new rows" and i get a simiral error message when i try to delete something (plus it deletes everything from the database not only the record chosen).. here is the code i use for the add and delete

I have a problem with binding navigator in vb2005 express. It won't update and delete records.
View 1 RepliesI am a newbie using VB.net in VS 2008. I took over a vb.net winform application that has a binding navigator in it. The users wanted to add 2 new fields to the form. I added the new fields to the SQL Server 2005 database. I refreshed the Data Source tab in the project. It recognizes the 2 new fields.
I dragged them onto the form. When I go to add a record through the application, it does NOT save these 2 new fields. I check the properties for these 2 new fields under "Data Bindings" and it shows under the "Text" property the correct Binding Source and column name. I need to store these 2 new fields to the table.
I have a form with a binding navigator on it. It also has a DGV and text boxes bound by the binding navigator. Everything works fine. If you scroll through the row's in the binding navigator it updates the DGV and text boxes at the same time. And also if you click any row in the DGV it automatically updates the text boxes.
Ideally I want to impletment some validation to make sure the users are not only filling in all the required text boxes but also that the data entered is correct.
I have some validation setup in SQL, for example not allowing nulls on particular columns but I really need to be more extensive in the validation than that.
Ideally I need some way of validating the current row selected whether it's an existing row or a new one, before moving to the next row or before save is clicked on the binding navigator. Firstly because the SQL validation messages are not very good, secondly because whilst the data may meet SQL's requirments, it may not be right. For example SQL might accept 12:00 as a time but the program specification requires the user to input within a certain time frame, i.e. 14:00 - 16:00.
Finally, I feel like the validation needs to be handled immediatly on the record that is displayed as ultimatley, the way the form is setup, allows the user to add and amend more than one record at once and if the validation was handled on 4 or 5 different rows then it would bring another problem of having to bring each row up to correct. Therefore I think the best aproach is to handle each row before allowing the user to move onto another one.
I am using VS 2008, VB, and an Access db. I cannot get the save button on the binding navigator to work. I dragged the table from the datasource onto the Windows form creating all of the controls, including the binding navigator. I can add records but I cannot update.

View 10 RepliesI use the binding navigator in my application, but when the resolution of the display gets to small and I have to use the scrollbars, then I get a problem. The scrollbars automatically scrolls down below the navigator bar instead of showing it when the window loads. I figured it out using focus or select. it now loads on top,but then I got a second problem.When I press on my tab-control it "autoscrolls" down again and puts the tab-control as the first visible thing on the screen instead of the navigation bar. How can I prevent that?
View 1 RepliesI am using the BindingNavigator control on my form. I want to use my own buttons instead of "BindingNavigator". I tried double clicking on "Binding NavigatorMoveFirstItem" button to see the code behind it. But nothing is there.What is the code to use the BindingNavigator but on my custom buttons? Actually I want to use my custom buttons but the same code which BindingNavigator uses and then I will delete the BindingNavigator.
View 7 RepliesI have a form application created with Visual Basic Express Edition 2008 which has a Binding Navigator that navigates through records in a database (Access .mdb file Added with the "Data Sources" wizard).

I'm stuck because all the backend database code is hidden.

View 1 RepliesI am wondering which code would apply to a refresh button in a datagridview form.
View 1 RepliesI use the Add new button (of the Binding Navigator) to clear the text boxes for a new record, but then have a Update button on the form where I do an Insert query to SQL, which works because if I refresh the table in SQL the new row is there.However when I then use the Binding Navigator 'move previous' button I get an error saying "Column 'AllowOverbook' does not allow nulls. " - now this is a column that is defined in the database to have 'Allow Nulls' = False, but I do not display this field on my form because in this case it is not required.Instead I have it included on my Insert statement and just set it to '0'
Also when you look at the table every entry in the AllowOverbook column is '0' and there are no NULLS.
I have a basic data entry form using a binding navigator and a details form. I do the validation in the dataset on the columnchanged and tablenewrow events. These work, and I check the haserrors property before saving, however if the user gets an error, when they get back to the screen, the current item has moved. Ideally, I'd like to have it stay on the item with the error: Private Sub DSHW_FACILITYBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FACILITYBindingNavigatorSaveItem.Click

I've got a datable on my form, it loads the data from the database and displays it just fine but when i add data to it it doesn't save it to the database... I don't know why but the save button on the data navigator is disabled by default but even when i enable it, enter data and click it, it doesn't save the data. (i dont think its the button i just thought it's worth mentioning that the save button is disabled by default when you drag a data table onto a form)

well, i am working on a project using tables by simply dragging and dropping them on a form.
from a single data set, i dragged 9 tables into 9 forms.. the fill method of tableadapter works whenever the form loads
now my problem here is, there's a problem with my binding navigator that the save and delete buttons aren't working..
this is actually my alternative method. since this morning.. i couldn't make my binding navigator work for my tables (i was surprised to see that there's only one working binding navigator from a single dataset, and because of that, i thought i could just use it to work for my 9 tables instead). still it doesn't work.. and i thought of using different forms for different tables so i could get the binding navigators work perfectly..
and yet, it doesn't make any change at all. still there is problems
is there any way to make this work?
how about adding codes into the delete button event in the binding navigator?
I am using a toolstrip binding navigator to access files and it works fine. I want to reset the navigator to the first file on a seperate button . Is there a simple way to duplicate the action of the toolstrip button "BindingNavigatorMoveFirstItem" when using another button?
