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?
View 2 RepliesI made button 4 on my form. When I run the program I find that it disappears.
I look at the visable property and I see that it is true. So what might be the problem. I also have button one that I put a message box it. When I hit the button durring run mode it will not activate. Have I missed up something here?
when i attempt to debug a program in visual basic studio 08 the black screen dissapears immediatly and i cannot read anything that appears. not sure if it is an option or a bug, but it makes the system relatively useless.
View 4 RepliesI 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.
View 8 RepliesShould 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?
View 3 RepliesI am loading a table from access in my form while clicking on a "load table"button:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnLoadtable.Click
Me.WoodsheetsTableAdapter.Fill(Me.WoodshopDataSet.woodsheets)
End Sub
The binding navigator should not be visible so I set the property "Visible" to "No"...
What is the code to include for another button called "Next" to use the functionality which is normally in the bindingnavigator to move to the next item in that table?
I wonder if it's possible to assign BindingNavigator.PositonItem with a datagridview selected row?
I have looked through msdn and it looks like it ain't - am i wright ?
All in all i've got a problem with delete item - it can only delete an item with number that's in PositionItem, while I'd like to delete current clicked row
I need to upgrade my application to a modern style interface component like Dotnetbar or Krypton,these doesn't provide a equivalent control for bindingnavigator so I have to create it with some buttons and textbox.I use bindingnavigator only for navigation as in the image
It is possible to create a user control (with 4 buttons and a textbox) that inherit bindingnavigator and to have new style buttons ?
I have a main form "Parent" and another "child" form. When I am filling a textbox in the child form the mouse pointer disappears. Then I hit the tab key to jump to a combobox. At this time when I move the mouse, the pointer doesn't come up until I click the mouse button. This is annoying and the user of my program doesn't like it. How can I keep the mouse pointer always on top. NOte: although the main form has the parent property as true, the other child form are not defined as child forms.

View 5 RepliesI have a custom contro which inherits directly from Treeview. Is there any way to handle some event related to when the TreeView Scrollbar appears (it does this when the height of the stack of visible nodes exceeds the height of the control) or "disappears"?
I realize if could set up a function which checks the ItemHeight * Nodes.Count, and compares this to the control height. However, this seems clumsy. I have been exploring the object browser (and anylized TreeView with Reflector) and have not found what I am looking for. If there is a way to access the ScrollBar Property at ALL within TreeView, I have not found it.
I am having a funny problem with OpenFileDialog that I just cannot solve. Using VB.NET 2008 Pro.
Problem: I run my program and click the menu item associated with this OFD and the OFD opens fine. When I select a file and click OPEN the dialog disappears then reappears. I click OPEN again and it disposes itself then loads the proper file into a form. The same thing happens with the CANCEL button as well.
Question: How do I go about coding the OFD to open a file that has been double clicked on thus bypassing dialogresult.OK . I can't seem to find an answer to this.
In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.
View 9 RepliesI 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.
View 3 RepliesI've made a form where I can scroll through some rows in a SQL with the BindingNavigator-control.

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)

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:

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 have a bindingNavigator and some textboxes connected to the bindingsource, in a childform, a form inside another form.I have a third form, a search function, and I need to change the bindingNavigator Position, when I choose a number in my "search" form.I have some code in my "Search" Form, but I caannot get it to update the bindingnavigator in my child form:

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.
View 1 RepliesMy 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.

Handles BindingNavigatorAddNewItem6.Click
HistoryBindingSource.AddNew()

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()
my program has been finished a year ago and then I didn't use it. but today I need to use it for some reason. I find it cannot be update when pressing the save button on BindingNavigator bar, here is the message
System.InvalidOperationException
When passing the modified data to DataRow collection，The update need a valid UpdateCommand.

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).
I'm creating a simple application whitch will allow users to add data on a form and stored in a database. I am using the BindingNavigator for this task, but i want the BindingNavigator to be in "addnewitem" mode on form startup.
View 2 RepliesI have created datagridview from my datasource using drag and drap. Without any changes it works fine, I can add, edit, delete and save. I added additional queries with my dataset which is fillby. My problem now is if I change fill with fillby the updateall is dosn't work anymore.
