Open frmDataGrid from Form # 1

[dorandoran]

This code on my form # 1 button.

        If txtDate.MaskCompleted = True Then
            Dim form As New frmDataGrid
            form.Show()
        Else
            MessageBox.Show("You must input a date")
            Exit Sub
        End If

I added a form "frmDataGrid" and used vb.net toolbox to create datagrid. I did pick data source and it's a Stored Procedure(@tDate is require parameter). How do I pass a parameter from my form #1 (txtDate) to frmDataGrid?

In C#:

create your frmDataGrid class like so...

public partial class frmDataGrid : Form
{
    private string date;
 
    public frmDataGrid()
    {
        InitializeComponent();
    }
 
    public frmDataGrid(string _date)
    {
        InitializeComponent();
        date = _date;
    }
}

Call it like so...

if (txtDate.MaskCompleted)
{
    frmDataGrid frm = new frmDataGrid(txtDate.Text);
    frm.Show();
}
else
{
    MessageBox.Show("C# is far superior to VB :)");
}

How do I pass a parameter from my form #1 (txtDate) to frmDataGrid?

There are two ways to do this. One way to do this is to modify your frmDataGrid's constructor. Another way is to add a Public member to frmDataGrid, and after you instantiate it, set the value.

I'll show you the first way. Add a parameter to the constructor. If you did not define a constructor, you need to add one.

So if you wanted to pass a String for example, do this in frmDataGrid:

 
Private paramS as String
 
Public Sub New(s as String)
        ' This call is required by the Windows Form Designer.
        InitializeComponent()
 
        ' Add any initialization after the InitializeComponent() call.
        paramS = s
End Sub
 

And you would have to change the way you call the form:

Dim form as New frmDataGrid("whatever string you want to pass")
form.Show()
