Passing Value Between WinForms

[Anddmx]

Hi,

I'm haven some problems moving value from winForms.

I have Textbox with hold propertyID and I need to move this value to form2 to finish running my query. Only problem is value comes over as NULL. Not sure what I'm doing wrong I have use GET / SET property few other times but not with winForms. When I debug I get "" for value from PropertyID.

CODE:

form1:

public string PropertyID
{
get { return propertyID.Text; }
}

form2:
form1 form1 = new form1();
string PropertyID = form1.PropertyID;


Thanks CLA

When you create a new instance of form1 inside form2 using the new operator, it initalizes PropertyID to empty string. What you need is a reference to the original instance of form1. Or at least the original value.

The technically correct way to do this is have the ownership of the forms contained in another class. It takes the value the user entered, and passes it onto the other form.

public AnddmxController
{
  public ProcessInput()
  {
    string propVal;
    form1 frm1 = new form1();
    frm1.ShowDialog();
    propVal = frm1.PropertyID;

    form2 frm2 = new form2();
    frm2.PropertyID = propVal;
    frm2.ShowDialog();

    if (frm1 != null)
      frm1.Dispose();
    if (frm2 != null)
      frm2.Dispose();
  }
}

Hope this helps.
Chip H.
