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.

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.

i have created dynamic buttons at runtime and i would like to disable them when a user clicks on a form button.This is the code i have for that button:
Dim intXX As Integer = 0
Do Until intXX = intX
userAvatar(intXX).Enabled = False
intXX = intXX + 1
Loop
The buttonNames is an array of all populated button names created at runtime. However, trying the .enabled = false at the end of that does not work. What other ways are there to do that with buttons created at runtime?

How can I disable buttons on some rows in an unbound datagridview, or at least make it appear that it isn't enabled? The enabled property of the cell doesn't exist, and the visible property is read only.

View 7 RepliesCan you temporarily disable a radio buttons CheckChanged Sub? I have a set of radio buttons in a groupbox and when the user selects one, I need to check if it's a valid selection. If not, I need to reset it to the previous button that was pressed. Below is an example of my
Private Sub rbGame_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbGame.CheckedChanged
t_indextype = m_indextype
m_indextype = "1"
[CODE]..................
In the above example, ResetButtons() changes the checked value of the radiio button selected to false and changes the checked value of the previous radio button to true. The problem is that when radio button rbGame gets changed, it causes the CheckChanged sub above to run again from the top. Is there a way to temporarily disable it from running while I make my changes and then re-enable it?
I have a group of radio buttons inside a groupbox and I don't want the user to be able to move the focus away from a button by using the arrow keys. I've tried the following keydown event, but it never gets fired:

' If an arrow key is pressed, maintain focus on this radio button

i generate a small HTML file on a hard disk, put the AxWebBrowser2 object navigate to the file, all works fine, but i need to diable all user interface on that object. If the user clicks on object, the page reloads completely and i need to avoid that behavior.
I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?

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 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?

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.

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.
