[RESOLVED] Datagrid validation in vb. (if statement)

[msboddie]

I have a datagrid with several columns, the first column is the release column. This column validate that the release is valid and validate that the release is in another table.

I have two private functions that help with the validation: Private Function CheckSatus(strRelease As String) As Boolean and Private Function CheckRelease(strRelease As String) As Boolean

What is currently happening:
When you enter an invalid release it turns the back color yellow.

What is expected:
It should hit the CheckSatus(chkValue) and turn back color red and stop.

Here is the code I currently have:

Private Sub gridUserEntries_CellLeave(sender As Object, e As DataGridViewCellEventArgs) Handles gridUserEntries.CellLeave
If (e.ColumnIndex = 0) Then
Dim currCell As DataGridViewCell = gridUserEntries.CurrentCell
Dim chkValue As String = currCell.GetEditedFormattedValue(currCell.RowIndex, DataGridViewDataErrorContexts.Display)

If Not (chkValue.Trim = "") Then
'Validate if release is in jobscopedb.IPJOBM table
If CheckSatus(chkValue) Then
currCell.Style.BackColor = Color.White
Else
currCell.Style.BackColor = Color.Red
btnUpdatePPUSRFS.Enabled = False
btnClear.Enabled = True
End If
'Validate if the Release Number is in the PPUSRFS TABLE
If CheckRelease(chkValue) Then
currCell.Style.BackColor = Color.White
btnValidate.Enabled = True
btnRetrieve.Enabled = True
btnClear.Enabled = True
Else
currCell.Style.BackColor = Color.Yellow
btnInsertPPUSRFS.Enabled = True
btnValidate.Enabled = False
btnRetrieve.Enabled = False
End If
Else
currCell.Style.BackColor = Color.White
End If

End If

If CheckSatus(chkValue) Then
    currCell.Style.BackColor = Color.White
Else
    currCell.Style.BackColor = Color.Red
    btnUpdatePPUSRFS.Enabled = False
    btnClear.Enabled = True
    Return
End If
'Validate if the Release Number is in the PPUSRFS TABLE
If CheckRelease(chkValue) Then
    currCell.Style.BackColor = Color.White
    btnValidate.Enabled = True
    btnRetrieve.Enabled = True
    btnClear.Enabled = True
Else
    currCell.Style.BackColor = Color.Yellow
    btnInsertPPUSRFS.Enabled = True
    btnValidate.Enabled = False
    btnRetrieve.Enabled = False
End If

When you post code, select the code block and click the # button in the post editor window ^
Your code formatting will be retained, and we can all read it easier...

Thanks so much Paul that worked.

So now I have another question:

I have a button that retrieves data and place the information in data grid, its currently working but I need to add a message box to it. If the back color in the grid is red when the button is click a message box appear to "Correct all red fields before continuing. I have tried to insert message boxes to test but in the for each loop the message box appeared for each red back color cell and that not what I need it to do.

Here is the code:
Private Sub Retrieve()

Dim con As OdbcConnection

So now I have another question

Then create a new thread and provide the information specific to that question. If the issue you originally posted about is resolved then mark this thread Resolved using the Thread Tools menu.

Also, .paul. asked yo to format your code and even told you how in post #3 and yet now you've posted a big wad of code without formatting it again. If you'd like us to volunteer our time to help, please do what you can to help us help you. Unformatted code is much harder to read so it wastes our time trying to read it.
