I can't pass data between two forms

I have a GridView in my form and I want when I click on a button to open another form and fill it with informations from the selected row in the GridView.

This is the code I tried in the form that contains the GridView:

private void barButtonItem13_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
   DataRow getRow = gridView1.GetDataRow(gridView1.GetSelectedRows()[0]);
   using (Collections_.ModifierCollection modifierCollection = new Collections_.ModifierCollection((string)getRow[1],(string)getRow[2]))
   {
      var result = modifierCollection.ShowDialog();
      if (result == DialogResult.OK)
      {
          // Just some code that I used
      }
   }
}

And this is the code I tried in that other form:

public ModifierCollection(String getKeyWordCollectionName, String getKeyWordEditeurName)
{
  collectionBox.Text = String.IsNullOrEmpty(getKeyWordCollectionName) ?
                                 "unknown" :
                                 getKeyWordCollectionName;
        editeurBox.Text = String.IsNullOrEmpty(getKeyWordEditeurName) ?
                              "unknown" :
                              getKeyWordEditeurName;
  InitializeComponent();
}

But it gives me an error in this line: collectionBox.Text = getKeyWordCollectionName;

Object reference not set to an instance of an object.

Most likely your collectionBox isn't created. Try to move it after InitializeComponent()
