Datagridview Default Error Dialog?
Jul 13, 2011
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'm sure most people on here have opened an OpenFileDialog or SaveFileDialog and set the SelectedPath property to point to some directory...
Has anyone done this on a Windows 7 machine and been able to point the thing to a Library? If so, what do you set it to?

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.

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'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 am trying to set the "ColumnHeadersDefaultCellStyle" property to the "GoudyHvyface BT" font and it will not change from the default. I am using Visual Basic 2008.
I have set the property properly with no success.
I have tried to set the property in code, using the suggestions in the MSDN and it kept throwing errors.
