c# datagridview in tabpanel

In my form i've a tabpanel with five tab. Every tab have a datagridview binded to a databes. All datagrid are filled correctly,but the event CellContentClick works only on the frist tab. I'm trying to retrive content on selected cell with this code:

//fristtabpag and datagrid1
private void dgw1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    text1.Text = dgw1.SelectedRows[0].Cells[0].Value.ToString();
}
//second tabpag and datagrid1
private void dgw2_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    text1.Text = dgw2.SelectedRows[0].Cells[0].Value.ToString();
}
//other....

And it works only on frist tabpage.

i use same code corrrectly fixed for other page, but i get an error for the index. How fix it?

You could try using the DataGridViewCellEventArgs like this: 

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {                       
        DataGridView dgv = sender as DataGridView;                                   
        text1.Text = dgv.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.SafeToString();
    }

Alternatively you could try using the CurrentCellChanged event and get the value from the CurrentCell property:

private void dataGridView1_CurrentCellChanged(object sender, EventArgs e)
    {
        DataGridView dgv = sender as DataGridView;
        if (dgv.CurrentCell != null)
        {
            text1.Text = ((DataGridView)sender).CurrentCell.Value.SafeToString();
        }
    }

(The method SafeToString() is a simple extensionmethod, all it does is check if the object is null before calling ToString(). If the object is null it returns an empty string)

From your code-example it looks like your eventhandlers does the same thing to different DataGridViews. By using the sender parameter, you can use the same handler for all the DataGridViews.
