Hello,i have the following code that creates a datagridview control and put it into a tab page of a tabcontroll, my problem is that i need to get somehow (mostlikely with an event handler (because i need allways to get the realtime selected row)) a value from a selected row in this data grid view to be used in another button. Anyone know how can i do this?

C#

private void button1_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveByKey("Database ImageTable");
            DataGridView datagrid1 = new DataGridView();
            Utile.Customtabpage.tabpage(tabControl1, datagrid1, "Database ImageTable");
            datagrid1.DataSource = Utile.DB.fillImgT(ConnectionSTR);
            datagrid1.BackgroundColor = Color.White;
            datagrid1.AllowUserToAddRows = false;
         
        }

//I know that my english is kinda bad so i`m sorry for that.
With respect, Aryx.

Hello

Try this:

C#

private void button1_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveByKey("Database ImageTable");
            DataGridView datagrid1 = new DataGridView();

            datagrid1.SelectionChanged += new EventHandler(datagrid1_SelectionChanged);

            Utile.Customtabpage.tabpage(tabControl1, datagrid1, "Database ImageTable");
            datagrid1.DataSource = Utile.DB.fillImgT(ConnectionSTR);
            datagrid1.BackgroundColor = Color.White;
            datagrid1.AllowUserToAddRows = false;
         
        }

Then Define a Method:

C#

void datagrid1_SelectionChanged(object sender, EventArgs e)
{
    var rows = ((DataGridView)sender).SelectedRows;

    if (rows.Count > 0)
    {
        //...
    }
}
