I have a d.g.v. with two columns. One is set as date and the other is set as decimal. If there is a row and a number is typed in the decimal column, you can delete it and leave the cell empty. However, the program will not let me delete the contents of a date cell and leave it empty. It just gives me the default error dialog saying that I need to put the contents in proper date form and it doesn't let me leave it blank.
How can I make it so that it allows me to leave the cell blank?

I've tried several variations of this. If the Cancel button is clicked on the dialog, an exception occurs, and a crash in an executable. I thought the "Exit" statement would take care of it. Not true. What I need is an error handler. In VB6, I used "On Error". I would prefer to not do that here.

I have a dialog that is displayed concurrently with the main form and it has a datagridview showing a list of x,y values. The user can actively change the DGV in the dialog, but if I reference the DGV from the main form, it will not capture the user changes, but report the original values that were in the cells. I'm sure there is some sort of refresh or update event I am missing, but I have tried all the VS suggested options for the DGV and the dialog that seem relevant with no luck.

I am getting an unknown error when I access one of my datagridviews. I get this error when I go to the tabpage where there is this datagrid and also when I put my mouse cursor over it.I don't know how to fix this because I don't know which code cause it. When I step through everything is ok, this error occurs at run time but doesn't show where and doesn't even stop the program.

On my Winforms app, I have a primary form with a DataGridView bound to a database Entity datasource.
The grid is set up not to allow inserts. Instead I have a button on my form that kicks of a second dialog where the insert takes place (ie. with friendlier ui than is possible with the DataGridView).
The insert is working fine.. query of the underlying table in db shows that the record has been inserted. However, I can't seem to get the DataGridView on the primary form to see the new data just created by the second dialog.
I have read many Stack Overflow q & a's and tried various solutions to get the DataGridView to refresh to show new data.. but nothing works.
This must be a common situation ?? Can someone suggest some VB.NET code that will work ?

I tried to make a phone book but I having some problems inserting it to the databank and then updating the Datagridview. I use a Dialog to input the contact details. I have 7 dialog's and 7 Label's.
Name + Textbox for giving contact details , ...
Then I click the button and I thought to use this code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'I have set it to false so they have to use the dialog to make the contacts but I don't think its the best way'
Form2.DataGridView1.AllowUserToAddRows = True
'Simple Check For checking phone number and Name has values(user must give the value)'

As part of a review of my program on Softpedia, the Reviewer stated the following: If you call on a piece of software and it is not installed on your computer the application will pop up a nasty error message that may discourage beginners. Popping a dialog saying the reason of the error or that the software is not installed on the system would be a great fix.

I'm running in to a bit of a strange error with an application I'm writing. I have a number of shortcuts on my computer desktop that take me to my various folders (documents, music, etc) and have always been able to navigate using them when I open a file through applications such as Word. However when I use an OpenFileDialog box in VB.NET and select one of these shortcuts to take me to the file I'm after I am getting the following error message...

I am using the ModalPopupExtender control to display a modal popup dialog when a button is click. The problem is that dragging the dialog results in an 'scrollleft is null or not an object' error. Here's a video demo and here is ALL the code: If possible, I'd like to resolve this problem w/o resorting to modifying the AjaxToolkit scripts themselves.

I have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?
