I need to remove all the buttons in my toolstrip so they can then be repopulated. But I have no idea how to remove them. I tried using a For statement:
For Each ToolStripButton In Mainwindow.FavouritesBar.Items()
Mainwindow.FavouritesBar.Items().RemoveAt(Mainwindow.FavouritesBar.Items().Count - 1)
Next MainWindow is the name of the form that FavouritesBar (The ToolStrip) belongs to.
I am calling this from another form, but I keep getting a "Collection was modified; enumeration operation may not execute." exception.
I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:- m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
I have an MDI container with a ToolStrip. I ran into a naming issue with images/icons. I removed the lines of code referring to the image of the buttons in the MDIForm.Designer.VB file. Then, in the actual designer, I imported the image file as a project resource and added this image to each button.
When I view the MDI form in the designer, the buttons appear normally, but when I run the app, the buttons are not there!
Should i have not edited the designer.vb file directly? Can this be fixed without recreating each button?
how can I stretch my toolstrip buttons? The size of my form is 300 x 250
I only have 5 toolstrip buttons, so the buttons only fill up half of my form. How can I make it so that the buttons stretch to the size of my form? So, that I can fill up the whole toolstrip?
VS2008 .NET 3.5SP1 I've got a MenuStrip with dropdowns and a Toolstrip with buttons. I don't want the button images in the image margin of the dropdown because they are too small to read properly. I can't seem to find the ShowImageMargin property (in either the MenuStrip or the ToolStripMenuItems) to turn the margin off. I've constructed the menu items in the designer.
There is a response to this question using C# - I am looking for a VB answer and the C# code is too deep for me. I have a custom user control and I have a toolstrip on it. I have certain default buttons on the toolstrip, but I want the user to be able to add additional buttons at design time. I exposed the Toolstrip.Items collection in a public property. I can open the collections editor in design time, but I cannot edit the collection.
I am dynamically creating buttons on a page, and want to be able to remove only certain block of them. I have no clue how to do this.. Right now I am clearing the WHOLE form and then redrawing everything.
Here is my code I am using to create.
Dim Buttons(99) As Button Dim cmd As New SqlCommand(strSQL, oSQLConn) dr = cmd.ExecuteReader()
I have a lot of buttons on a form (144) that need to be removed. All their names begin with "R". So I used this piece of code.
Sub RemoveBookingButtons() Dim cntrl As Control
[CODE]........................
However whenever I run this sub function, it deletes every other button starting with "R". better code or point out if the flaw is in that piece of code or it is hidden somewhere else in my program?
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?
What I would like to do is to have four different buttons (e.g., buttonA, buttonB, buttonC and button D). I wanna give the following instruction to the people: press these buttons in the following order: first buttonA, then buttonB, then buttonC and last buttonD. If they obey this instruction then a picture will be displayed, for instance a happy face. All the other combinations will not activate this picture to be displayed, or in other words, there won't be any consequence. I would also like to save this data using windows note pad e.g., writeline (1, xxxxxx). Is there any chance I will make it?
I'm using a dialog form with two buttons and two Radio buttons.I'm oppening this Dialog when a button is clicked on the parent form.My situattion is when the Dialog opens the code in the button event continues to execute, but I only want it to continue to execute only after a button from the dialog form have been clicked
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click If multipleEXT = 2 Then Extension.Show()
i need to get some buttons to interact with other buttons on screen when i click then, as each indivual button gives a slightly different result.imagine this:[code]....
then i need then to hide different buttons depending on which button was pressed. so say i pressed button 1 then all the buttons showed but alternativly if i had of pressed 2 then say button 5 and 6 disapear.managed to get one way to work but then i would only ever end up with the first results every time.
My VB application is behaving strangley. I have form with fairly large number of controls. I am using case against radio buttons. after curtain number of buttons, it stops responding to more radio buttons.
Then I tried to split controls in to 2 form but now my form.showdialog() too now working properly. It takes new from names but show the old form when running.
I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
I'm making a little webbrowser just for the heck of it, And i want to know if you can use a toolstrip for a bookmarks bar. I have it laid out, I just would need the code to make the buttons work.
Is there another way to add a Context Menu to a ToolStrip other than using the MouseDown Event? I want to use it to let people select to either show text labels on buttons in the ToolStrip or turn them off.
I am trying ot call my summary data from my summarytoolstripmenu, to the Public Class Form2 Private Sub FormSummary_Activated(ByVal sender As Object, ByVal e As System.EventArgs)'Display summary information
End Sub Private Sub ButtonOk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonOk.Click 'Hide the form Me.Hide() End Sub End Class
But for some reason I must be missing something in the text because it still pops up my messagebox instead of the seperate form i intend to call up
I would like to make an example to insert a DateTimePicker control to a ToolStrip, but not like the examples I found on the forum, otherwise, so that when you want to add controls to the ToolStrip, within TexBox controls, splitButton, Label, ComboBox, etc. also ....., DateTimePicker control appears as a possible control to add,
I created a toolstrip with some buttons. I have a form with some objects (like textbox,checkbox,button etc.) and when i get the focus on last item,when i finish to compile i need with tab on keyboard to get focus on save button on the toolstrip.
