My suggestion would be to create a button click handler. Then in the click handler create the 2 textboxes. Then in the button 2 click handler, take the data from the 2 textboxes, concatenate the strings and put them in the first textbox.

Hi,
In button1 click event add the TextBox like:

C#

TextBox t1 = new TextBox();
t1.ID = "TextBox1";
TextBox t2 = new TextBox();
t2.ID = "TextBox2";
Panel1.Controls.Add(t1);
Panel1.Controls.Add(t2);
//Now your both textboxes are added into panel.
//You can add it wherever you want.

In button2 click event find TextBox value like:

C#

TextBox t1 = (TextBox)Panel1.FindControl("TextBox1");
TextBox t2 = (TextBox)Panel1.FindControl("TextBox2");
//Now you found your both textboxes.
//Get the values using t1.Text and t2.Text

Isn't this too easy.
Anyway try it.
All the best.

Thanks for your reply but it is still not working for me.I did like this as the way you suggest.two textbox's created when i clicked on button1 but when I am entering some value into those two textbox's and click on button2 it unable to find those two new generated textbox's.I traced the program but when i press button2 the page is reloading so the new generate dynamic controls are also loading for that it value,id every thing vanish I think.try once,thanks once again Amit for your reply

Where you are writing these codes? Write it inside Not IsPostBack under page load or inside button1 click event. Can you show me your full coding here?

<asp:Panel ID="Panel1" runat="server">
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
<br />
<asp:Button ID="Button2" runat="server" onclick="Button2_Click"
Text="Button2" />
<asp:TextBox ID="TextBox1" runat="server">

protected void Page_Load(object sender, EventArgs e)
{
}

protected void Button1_Click(object sender, EventArgs e)
{
TextBox t1 = new TextBox();
t1.ID = "TextBox2";
TextBox t2 = new TextBox();
t2.ID = "TextBox3";
Panel1.Controls.Add(t1);
Panel1.Controls.Add(t2);

}

protected void Button2_Click(object sender, EventArgs e)
{
TextBox t1 = (TextBox)Panel1.FindControl("TextBox2");
TextBox t2 = (TextBox)Panel1.FindControl("TextBox3");
}

Hi,
The best way to add the controls is in Page_Init event. Because this time only the controls will be created.
Try this:
protected void Page_Init(object sender, EventArgs e)
{
TextBox t1 = new TextBox(); t1.ID = "TextBox2";
TextBox t2 = new TextBox(); t2.ID = "TextBox3";
t1.EnableViewState = true;
t2.EnableViewState = true;
t1.ViewStateMode = ViewStateMode.Enabled;
t2.ViewStateMode = ViewStateMode.Enabled;
Panel1.Controls.Add(t1); Panel1.Controls.Add(t2);
t1.Visible = false;
t2.Visible = false;
}

protected void Button1_Click(object sender, EventArgs e) {
TextBox t1 = (TextBox)Panel1.FindControl("TextBox2");
TextBox t2 = (TextBox)Panel1.FindControl("TextBox3");
t1.Visible = true;
t2.Visible = true;
}

protected void Button2_Click(object sender, EventArgs e) {
//FnAddControls();
TextBox t1 = (TextBox)Panel1.FindControl("TextBox2");
TextBox t2 = (TextBox)Panel1.FindControl("TextBox3");
}

All the best.
