    Can you show your code that is loading the data.

    Generally speaking you would change youre connection string conditionally as per the radio button value

    No you wouldn't change the connection string, it connects to the database file not individual tables. You would change the SQL command the retrieves the data.

    You could do this in the Radio Button "CheckedChanged" event.

    the base load is done through the properties setting on the datagridview. i was wondering if there was a means to adjust that instead of the connection string use

    Re: DataGridView Data Source Question

    I've already said where to make the datagridview datasource change, are you asking how to change the dgv datasource? If so, then you need to provide more information about the datasource and post your current code. It will be a lot easier to help you if you provide a Full and Clear explanation.

    Re: DataGridView Data Source Question

    yes wes that is exactly what i am asking. the overall dataset is comprised of three tables in a connected resource database. in the properties view of the dgv i have the datasource set as DailyBindingSource in reference to the daily table. how would i programatically tell that property to adjust to the sundaybindingsource or specialbindingsource as needed based on a radio button checked on an alternate form. code as waiting is as follows
    Private Sub RBDaily_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RBDaily.Click, RBSunday.Click, RBSpecial.Click
    Dim rad As RadioButton = CType(sender, RadioButton)
    Select Case rad.Name
    Case RBDaily.Name
    Form1.DataGridView1.DataSource =
    Case RBSunday.Name
    Form1.DataGridView1.DataSource =
    Case RBSpecial.Name
    Form1.DataGridView1.DataSource =
    End Select
    End Sub

    Re: DataGridView Data Source Question

    Well that's a start, so your saying the Radio buttons and the Datagridview are on different forms?
    Which form is this code on,
    Code:
    Private Sub RBDaily_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RBDaily.Click, RBSunday.Click, RBSpecial.Click
    Dim rad As RadioButton = CType(sender, RadioButton)
    Select Case rad.Name
    Case RBDaily.Name
    Form1.DataGridView1.DataSource =
    Case RBSunday.Name
    Form1.DataGridView1.DataSource =
    Case RBSpecial.Name
    Form1.DataGridView1.DataSource = 
    End Select
    End Sub
    Are all the bindingsources in the same form as the dgv?

    I still think you should be using the Radiobutton CheckedChanged event, like
    Code:
        Private Sub RBSunday_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton1.CheckedChanged
            If RBSunday.Checked Then
                Form1.DataGridView1.DataSource = "yourdatasource"
            End If
        End Sub

    all binding sources are on form1 with the dgv

    Code:
        Private Sub RBSunday_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton1.CheckedChanged
            If RBSunday.Checked Then
                Form1.DataGridView1.DataSource = Form1.sundaybindingsource
            End If
        End Sub
    That would be my guess but I can't be positive because I never use Default Form Instances like your doing. I don't like coding like that.
