I have added a button in datarepeater. If clicked once, it executes code and Button.text should change to Yes. Clicked again, it executes the opposite code and button.text should change to No. Codes are being executed (I am using flag variable) but Button.text is not changing.
How to change this text. I am simply trying Button.text="Yes" but probably I need to give some reference of the row no. too. How to do it?
Please advise.
Thanks

Please check this question:
Handle Button Click in WinForm DataRepeater C# Power Pack
Also: the CurrentItem property has a property named Controls that allows you to access its child controls like this: CurrentItem.Controls["OKButton"]

I am using vb.net 2008, I added a button from design view in one of my forms.It shows in the form design view, I gave it the click code to load another form but after I run the program and look in that form, it does not show the button that I added while I run the program. what is the problem? And What are the solutions?
Thanks!
As you can see, I added a Back Button here
THis image is while I run the program. Back button is not displayed here.
I would suggest running something like this in order to see if the control is there. Listing if it is Visible would also be helpful.

Private Sub GetControls()
For Each GroupBoxCntrol As Control In Me.Controls
If TypeOf GroupBoxCntrol Is GroupBox Then
For Each cntrl As Control In GroupBoxCntrol.Controls
'do somethin here
Next
End If
Next
End Sub
The only way I can help you without you providing us more information like code or error info if exist (or maybe a warning), I will suggest you to copy the code from your button then delete the current button and a new one. Then paste the code back to new button.
And make sure you don't hide or change the visible property button somewhere in the code. If you are working with positioning in the code make sure you don't move your button.
Thank you for your support. The problem was that it was running the old .exe file. I deleted the old .exe file from the /bin/debug directory. And after I ran the program, it created me a new .exe file and hence my problem was solved.
Thank you again.
I have a problem while showing the PopMenu control in VB.NET. Where as in VB6 after showing PopUpMenu control holds on the screeen event after we have code after that also. But when we convert that to VB.NET we get ContextMenu.Show() the control is not holding on the screen and executing the next statements. This statements has to execute after clicking on the menu item in VB6. This is not happening.
Can you help me regarding this?
ShowDialog() would block the code but unfortunately ContextMenu Doesn't have that method. You need to use a Form to get this functionality.
Hi I have a VBA application with a combobox selection option.One of the combobox option is Other which when user select that option an invisibled label will pops up and prompt the user to fill the txtOther control.now my question is how I can get rid of the prompted label and make it to invisible after user fill the txtOther and move(focused)in other control?
here is a shot of my app:
Thanks for your time and help
It depends on how often or when you want the check to be done. I couldn't find a good reference to show you all of this, but you can view your VBE.
Within the code behind your userform you can use events for the text box.
If you want the check done every time you leave the text box:
Use the TextBox_Exit event.
If you want it to fire whenever the contents are changed, used TextBox_Change. There's lots of options, but based on your explanation I'd probably use Exit.
This answer shows some syntax examples for using the Textbox_Exit event.
I have a DataGrid and a DataForm. I'm assigning data to the DataForm with the currently selected Item in the datagrid individually as DataForm.CurrentItem. This means that I do not have any Next/Previous button on the DataForm and the user can switch to any row in the DataGrid.
My problem is that although I have set the property AutoCommit="True" on the DataForm, if the user edits something and clicks on another record in the DataGrid, it crashes.
How can I force it to save the DataForm when the user moves away from the form?
I got this working but I'm not sure whether this is correct. On SelectionChanged event of datagrid I added the following:
DataForm.CommitEdit();
and it stopped crashing and giving me the error. If anyone else has a better solution please do let me know.
I need a form width a checkbox "Don't show this again" for my winform,
but how can i make this so when my Form1 loads it checks the state of the checkbox using the getsettings option?
How can is save the checkbox state to the registery? and how do i get the state?
If Form2.Checkbox.checked = Getsettings() Then
Form2.showdialog
Else
Goto Skip
End IF
Skip:
Windows Forms has built-in support for that, you don't need to write any code. Select your check box. In the Properties window, scroll to the top on expand the "ApplicationSettings" node. Click on "Checked" and drop-down the combobox. Click New. Set the Name property to something meaningful.
Done. Your check box will always restore with the last selection that the user selected. Don't call Show() when it is turned on, dispose the form right away.
The main crux of the question is "how do I read and write value to and from the registry."
See here for a great overview complete with code.
You're beginner so here are a few tips on your code sample:
Name your objects more verbosely. Form2 will mean nothing to you a few hours from now.
Do not use Goto. Just don't. Please. You either show the dialog or you don't. The whole Else block with the Goto in it is just not necessary.
Few more things you'll need to do to get this working:
Handle the CheckBox checked event and write either a 1 or 0 (or T or F) to a registry value
Read that registry value in your GetSettings method
You might want to pass a parameter to GetSettings that specifies exactly which setting you need because you'll probably want to reuse that method for other settings as well
