yes it is possible but you need to give the row index that is the row number correctly during the operation

Hello ,

put your textBox in Item template and write hard coded "AutoPostBack="True" ontextchanged="txtBox_TextChanged" " on that textBox on aspx page after that

in code behind create event of that text box Like -

C#

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

It will work in gridview for textchange event.

XML

<asp:TemplateField HeaderText ="Sch.End Date" >
                    <ItemTemplate >
                        <asp:TextBox ID="txtBox" runat="server" ontextchanged="txtBox_TextChanged"></asp:TextBox>
                    </ItemTemplate>
              </asp:TemplateField>

Dynamic Controls not avaialbe after postback reason is simple. As web is disconnect in nature it create one object of your page then create required HTML using that and send back to browser that renders it. So ViewState comes into picture to take care after post back and mange control on page despite multiple postbacks. Means dynamic controls not added to ViewState? Yes.

However any thing on HTML page that has type of input has ability to sent data to server. Means your text box is input type and does post data So how to get that value . Look below

if I add some control to page on page load like

C#

if (!IsPostBack)
            {
                TextBox t = new TextBox();
                t.ID = "txt1";
                pnl1.Controls.Add(t);

            }

then I can get values after postback as

C#

if (Request["txt1"] != null)
            {
                value = Request["txt1"];

            }

This is just concept not exact solution to your problem .. I guess you get the logic.
