well, sirs,

I've got a problem of using textbox in aspx page which declared in c# page_load function page, using in click_button function. i've got the error message that the textbox tb_1 is not recognised.

the code is the following :

aspx page :

<div>

<asp:button id="bt_3" runat="server" Text="push_variable_confirm" onclick="click_bt_3" />

<br />

<asp:table id="table_1" runat="server">

</asp:table>

<br />

</div>

c# page :

public partial class WF_MS_jicixipi_testpro11 : System.Web.UI.Page
    {
TableRow row = new TableRow();
//int i;
int NumeroTextBox;

protected void page_load (object sender, EventArgs e)
{
function11_load();         
bt_3.Click += new EventHandler (click_bt_3);
}

protected void function11_load()
{
 int[] numbers = { 0, 1, 2, 3, 4 };
foreach (int i in numbers)
{
NumeroTextBox = NumeroTextBox + 1;  
TableCell cell = new TableCell(); 
TextBox tb_1 = new TextBox(); 
tb_1.ID = "tbok" + Convert.ToString(NumeroTextBox); cell.Controls.Add(tb_1); 
row.Cells.Add(cell); 
} 
table_1.Rows.Add(row); 
}

protected void click_bt_3 (object sender, EventArgs e)
{
tea_1.Value = tb_1.Text; //------ OR ------ tea_1.Value = tbok1.Text;
// théoriquement, :(, ça marche !!!!!!!!!!!!!!!!!!!!!!!!!!!!
}

}

thanks for resolving my problem.

I found the solution. i declare the textbox directly in class part with the attribute public and I create new textboxs in the function, it's so ok, the textbox tb_1 is recognized on click button.

I return the problem in a other side, i would to used the same function with asp:table and textboxs calling into click_button and used the value of textboxs sent to textarea with an other button. the problem is to recognize the textboxs in the second button bt_3.

the code is the following :

 TableRow row = new TableRow();
int NumeroTextBox;
public TextBox tb_1;
protected void page_load (object sender, EventArgs e)
{
bt_2.Click += new EventHandler (click_bt_2);
bt_3.Click += new EventHandler (click_bt_3);
}
protected void click_bt_2 (object sender, EventArgs e)
{
 int[] numbers = { 0, 1, 2, 3, 4 };
foreach (int i in numbers)
{
NumeroTextBox = NumeroTextBox + 1;
TableCell cell = new TableCell();
tb_1 = new TextBox();
tb_1.ID = "tbok" + Convert.ToString(NumeroTextBox);
cell.Controls.Add(tb_1);
row.Cells.Add(cell);
}
table_1.Rows.Add(row);
}
protected void click_bt_3 (object sender, EventArgs e)
{
TextBox tb = (TextBox)table_1.FindControl("tbok2");
tea_1.Value = tb.Text;
                          // théoriquement, :(, ça marche !!!!!!!!!!!!!!!!!!!!!!!!!!!!
}
