从一种形式显示数据到另一种形式的标签

Question

I'm currently having problem in displaying my transferred String data from the my 1st form to the second one. I tried putting a button in my 2nd form to check if the data is transferred, and I confirmed that the data was transferred by using MessageBox.Show() command. But when I try to assign it to my Label the Label text does not change. Here is my Sample Code:

First Form: Data transfer is being triggered by clicking a cell in my dataGridView

    private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        PopupSummary f = new PopupSummary();
        f.searchText = dataGridView1.CurrentRow.Cells[0].Value.ToString();
        this.Hide();
        f.ShowDialog();
        this.Show();
    }

Second Form:

     public string searchText = "";
private void PopupSummary_Load(object sender, EventArgs e)
        {
            label1.Text = searchText;
        }

Note:

label1 is inside a tableLayoutPanel.

My main problem is that the label.Text does not change the text of my current label even if the data was successfully transferred. Thank You.

Your problem is that you're assigning your new text to searchText , not to label1.Text . The only time you assign anything to label1.Text is on form load, in PopupSummary_Load , when you set it to the value of searchText . Simply changing the value of searchText after that won't cause the label text to be updated.

You can do any number of things now that you know what is going on, but here is a simple one:

f.label1.Text = dataGridView1.CurrentRow.Cells[0].Value.ToString();
