in this code how can i get the Text of Button in C#

hi developers i am using this code it is working fine for me , but i am having a small doubt .

protected void Page_Load(object sender, EventArgs e)
{
string query = string.Format("SELECT roomno from AD_Rooms_Master order by roomno");
try
{
DataTable dt = GetData(query);
for (int i = 0; i < dt.Rows.Count; i++)
{
Button btn = new Button();
btn.ID = "btn" + (i + 1);
btn.Text = dt.Rows[i]["roomno"].ToString();
btn.Click += btnLoadButton_Click;
pnl_btns.Controls.Add(btn);
}
}
catch (Exception ex)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "Message", "alert('Error occured : " + ex.Message.ToString() + "');", true);
}
finally
{
//cmd = null;
//conn.Close();
}
}
protected void btnLoadButton_Click(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "button", "alert('Room no " + (sender as Button).Text + " selected');");
}

could you tell me instead of this how can i get the value by using c# code , because then only i am validate the answer is correct or wrong .

ClientScript.RegisterClientScriptBlock(this.GetType(), "button", "");

thanks with
