I have an Invoice form with several private TextBoxes. I want to pass some values from my DataGridView in search form to those TextBoxes in Invoice form(when I press Enter for example).
What I want to do is to pass the values of the current selected row in the DataGridView to be passed to certain TextBoxes in Invoice Form:
I could illustrate this in the following code:
(I know how to get the values of selected row in datagridview my question is just the title...)

if (e.KeyCode == Keys.Enter)

{

    SqlCommand sqlcmd = new SqlCommand("SELECT ID FROM X WHERE ID=" +

                        dataGridView1.CurrentRow.Cells[0].Value + "", sqlcon);

    SqlDataReader sqldr = sqlcmd.ExecuteReader();

    while (sqldr.Read())

    {

        InvoiceForm.CodeTextBox = sqldr[codecolumn].Tostring

        InvoiceForm.NameTextBox = sqldr[Namecolumn].Tostring

        InvoiceForm.BlahTextBox = sqldr[Blahcolumn].Tostring                               

    }

}

which throws the following error at me:

codeTextBox is private... not able to do so because of protection
level...

I think I have to make a public static class to do so, but I dont know how.
How I tried:

 private string RetrivedCode;

        private string RetrivedName;

        private int RetrivedQTY;

        ...



    Public Form1(string CodeTextBox , string NameTextBox, string BlahTextBox)

    {

      this.CodeTextBox= RetrivedCode; 

      this.NameTextBox= RetrivedName; 

      ... and so On 

    }

which errors:

cannot implicitly convert type 'string' to
'system.windows.forms.textbox'.

Have you tried to change the access level of your CodeTextBox to public inside the InvoiceForm which is called InvoiceForm.Designer.cs file.

Well, the error is quite clear, you're trying to convert type 'string' to 'system.windows.forms.textbox'.

while (sqldr.Read())

{

    //textbox                  string

    InvoiceForm.CodeTextBox = sqldr[codecolumn].Tostring();

    InvoiceForm.NameTextBox = sqldr[Namecolumn].Tostring();

    InvoiceForm.BlahTextBox = sqldr[Blahcolumn].Tostring();

}

if you instead set the text property on the textbox, the error goes away.

while (sqldr.Read())

{

    // Note the ´Text´ property.

    InvoiceForm.CodeTextBox.Text = sqldr[codecolumn].Tostring();

    InvoiceForm.NameTextBox.Text = sqldr[Namecolumn].Tostring();

    InvoiceForm.BlahTextBox.Text = sqldr[Blahcolumn].Tostring();

}

UPDATE:

The same thing really, even if it's the second part that is the part that is throwing errors. I assume CodeTextBox is a text box?

this.CodeTextBox.Text = RetrivedCode; 

this.NameTextBox.Text = RetrivedName; 

But you're asking the wrong question. Because you don't have to "make a public static class to do so". If you make your textboxes protected (if your second form inherits the first form) or public instead of private, you'll be able to assign the value directly in accordance with my first examples.

If your text box neccessarily has to be private, use a public or protected accessor or a public method that sets the value of the Text property of the Text boxes.
