Enable On BindingNavigator The AddNewItem?
Dec 3, 2011
I'm trying to bind the BindingNavigator to a BindingSource. It works very good, but the problem is the yellow plus icon is disabled. How can I make it enabled?
I created manually with code the dataset, tableadapters and the bindingsource, but when I bind it on the bindingnavigator it shows the records but it doesn't enable "Delete" and "Add Item".
Code from comment:
Dim connstr As String = "Data Source=" + Application.StartupPath + "Prueba.sdf"
Dim conn As New SqlCeConnection(connstr)
Dim cmd As New SqlCeCommand("SELECT * FROM datos", conn)
[Code]....

I want to allow the user to enable or disable a textbox by clicking either a button (enable) or the reverse. (disable) if the user clicks the enable button the textbox should receive the focus.

I have a tab control with several pages. Within a page I have a panel. When I drag and drop a database to the panel the datagrid view is placed on the panel, but the bindingnavigator is placed outside the tabcontrol. Running the application shows only the bindingnavigator, which seems to have blocked the tabcontrol. If I cut and paste the bindingnavigator to the panel, and running the application shows the page with the bindingnavigator at the top and the datagrid below. However, the bindingnavigator no longer allows me to add and save entries to the database. I made sure all the properties were the same before and after i cut and pasted the binding navigator.As a test, I removed the tabcontrol, dragged and dropped the database to the empty form, and everything worked.

I've made a form where I can scroll through some rows in a SQL with the BindingNavigator-control.
Now I want to use the properties of this control in my code. Is it somehow possible to check if it has reach the last page/row? I want a button to be displayed then.

I want to Bind a BindingNavigator to a table using OLEDB or any other method (excluding the automatic stuff for increased complexity of my CW). I bound the Data Grid to the data using the following code
Try
Dim DA As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter("SELECT Question.Question_ID, Question.Question_no, Question.Question FROM Question INNER JOIN Quiz ON Quiz.Quiz_ID = Question.Quiz_ID WHERE Question.Quiz_ID =" & GetID(combQuiz_Title.SelectedItem), myConnection.GetConnection)
[code]....
Then I created my own delete and save commands. But I dont how to do the same using BindingNavigator

I have one datagridview control, a BindingNavigation and a Binding control on my form. I populate the datagridview control through the code. Moreover, the datasource properties of the DatagridView and the Binding controls are assigned a value through code (I didn't specify anyting in the properties window). The same for the bindingsource property of the BindingNavigation control (I assign a value trhough code). My code is the following:
[Code]...
This code brings and shows the right results in the datagridview control, but the navigator control is inactive. I know that I have to bind the controls(DataGridView + BindingNavigator) to the BindingSource control. Is this a problem that I tried to do this by coding?

I am trying to Disable the "Move First", "Move Previous", etc in a Navigator Bar. I want them Visable, just disabled. In other words, I want them to show (grayed out), just not clickable. In the Move First properties I set Enable = False and Visable = True. It looks grayed out in the form design but when I run it, the arrow is still clickable. If I make Visable = False, the button does not show up in the app.

Iam new to VB and have looked at Beths tutorial Videos. I was useing VB for 10 years ago and it have happen alot since, but the concept i pretty mutch the same. Iam useing VS2008 and VB and think your videos is great but in the real world the bindingnavigator is not so sexy to have in a application so I want to have my own buttons for creating new records, movenext, delete etc. When I was using VB4 i think the syntax was recordset.movenext but this seams not to work in 2008.

My problem is I click Save and it tells me the update is successful (via my code) but it then deletes the record and shows me the last one again, so it's not really updating.
Code:
Private Sub BindingNavigatorAddNewItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles BindingNavigatorAddNewItem6.Click
HistoryBindingSource.AddNew()
[Code] .....
I tried just having it write "test" to a few rows.
I also have this other method (doesn't work either) that maybe a better way to try? I get an error on the dsNewRow= line saying it's not set to an instance of an object.
Code:
Private Sub SaveToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripButton1.Click
Dim cb As New OleDb.OleDbCommandBuilder(data)
Dim dsNewRow As DataRow
dsNewRow = ds.Tables("History").NewRow()

I am using VS2008 on Windows XP SP3. I have a form with two pairs of dependant comboboxes which are bound to a SQL database table. In each pair, the second combobox's choices are dependant upon the selection of the first combobox.
Both pairs of comboboxes behave as expected. However, when I use the binding navigator to look through other existing records, the text in the second pair of comboboxes disappears on records that already have selections.
The database table still holds the information, but it just doesn't display in the combobox. Again, this only happens on the second pair of comboboxes, not the first pair and both sets of comboboxes are set up exactly the same (albeit on different tables).

how I can disable the various button on a BindingNavigator control? For instance, if a user is adding a member I want to disable the Delete button and all of the Move arrows, plus the ability to change the Position number.The same applies to clicking the Delete button. Diable the Add & Move buttons, etc.I tried BindingNavigatorMoveFirstItem.Enabled = False but that has no affect that I can see. I can still click the movefirst arrow and move away.

In VB2008, the BindingNavigator control had a Update button as its rightmost button. The button is not present in the second beta of VB2010. Will the Update button also be missing in the final release of VB2010?

I need to use the BindingNavigator to cycle thru the records of one of the tables in an Access database. The table has 5 text fields and 3 image fields. On a form I have placed 5 TextBoxes and 3 PictureBoxes. I included a BindingSource control and BindingNavigator control and configured them. This automatically generated the TableAdapter, BindingSource and Dataset. I then manually bound each TextBox and PictureBox using the DataBindings area in each of their Properties. I can run the program and display the records, but only the Text fields show anything. The images are not displayed in the PictureBoxes.

All of a sudden a bindingnavigator that I use has started disappeared when I run the program. It disappears in the design view too, but if I click its name down below (where all the datasets and bindingsources go) it comes back. Then once I run again it doesn't show up. I know it's still technically there because no errors in code occur, but why is it doing this?

Should I get a BindingNavigator when I drag and drop my dataset onto the datagrid that I've placed onto my form? I'm using SQL CE, get the bindingsources, tableadapters, and the columns show up on my form, but do not get a BindingNavigator.Do I need to add one manually, or is this not an option on mobile device development in VS 2008?

I'm using vb.net on vb 2005, I create datagrid view that when i click search button on the main form. It will show datagrid view that I want and when i click OK to select any record, the selected record will show on the desire text box in the main form. The problem is the record i choose is record no. 5 of all 10 record but the Bindingnavigator tools bar show that it's the first record of all 10 and when I click Next record arrow, the error message show that the 'PK column name' is unique and the 'value of the PK from my selected record' is already exist.

One of the VBF member was asking how to add a close button on the BindingNavigator control once and reuse it on all other forms, so I try to create a custom bindingnavigator class that inherits the BindingNavigator class.Below is the inherited class:
[Code]...
The thing that I can't figure out is that it looks OK in design mode, but at run time, the custom binding navigator shows 2 "Close" buttons. Only one of them will close the form when clicked, the other one doesn't function. See the attached image.

Visual Studio Express 2010. Windows Forms Application. New MDF Database. Add a table, put some data in it. Now, from the data sources window drag a DataGridView over to the Form1, drop it. There is no BindingNavigator created with it, so I drag on over there from the toolbox. Run it and the BindingNavigator does nothing. Why/how do I make it talk to the DataGridView?
