Writing a value to a datagrid
Posted on 2016-08-04
Hello,
I have an application that allows user to add a new record in a datagrid view for a list of users; small table.
I check to see if the user 'forgot' to add certain fields required by my program. If they forgot the field I write a default value for them. The situation is this:
1. I ADD a new record
2. The user is entered just fine while leaving out these two fields that I'm checking for.
3. This code errors out telling me that:
An unhandled exception of type 'System.ArgumentOutOfRange
I sure hope that you can help me!
Dim x
x = Log_In_CredentialsDataGrid
If x = "" Then Log_In_CredentialsDataGrid
Dim y
y = Log_In_CredentialsDataGrid
If y = "" Then Log_In_CredentialsDataGrid

if you try and convert a NULL to a string you will get problems, test for it first
if Log_In_CredentialsDataGridView.SelectedRows(0).Cells(5).Value is Nothing Then
Log_In_CredentialsDataGridView.SelectedRows(0).Cells(5).Value = 5
Endif
if Log_In_CredentialsDataGridView.SelectedRows(0).Cells(6).Value is Nothing Then
Then Log_In_CredentialsDataGridView.SelectedRows(0).Cells(6).Value = 0
Endif
