Hello guys!
I need your help.
This is code behind in my net page (C#).

I use the Page.ClientScript.RegisterStartupScript method, but I need print in alert the resume numbers of strDAA variable.
If I have only one variable strDAA the script working, but if I have more numbers of variable strDAA the script print only last value.

I need resume all operation execute in my script in the alert window.

Could you please help?
Thanks you very much for your help

Code:
 protected void btnUpdate_Click(object sender, EventArgs e)
    {
        OdbcCommand cmd = new OdbcCommand();
        myConnectionString.Open();
        cmd.Connection = myConnectionString;
        int myValue = 0;

        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            CheckBox chkUpdate = (CheckBox)
               GridView1.Rows[i].Cells[0].FindControl("chkSelect");

            if (chkUpdate != null)
            {
                if (chkUpdate.Checked)
                {
                    ....

                    strDAA = ((TextBox)
                        GridView1.Rows[i].FindControl("DAA")).Text;
                    ....

                        string myStringVariable = string.Empty;
                        myStringVariable = "OK for DAA " + strDAA + " ";
                    }
                    else
                    {
                        string myStringVariable = string.Empty;
                        myStringVariable = "Error for DAA " + strDAA + " ";
                        ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + myStringVariable + "');", true);
                        myValue = 1;
                    }
                }
            }

        }

        if (myValue == 0)
        {
            GridViewBind();
        }

        Page.ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + myStringVariable + "');", true);

        myConnectionString.Close();
        myConnectionString.Dispose();
    }
