I just thought I'd add a beginning to the solution I am searching for.
First a simple test.aspx:
<asp:UpdatePanel ID="uPanel" runat="server" ChildrenAsTriggers="true"
UpdateMode="Conditional" >
<ContentTemplate>
<asp:PlaceHolder ID="place1" runat="server">
</asp:PlaceHolder>
<asp:Button ID="btnAdd" runat="server" Text="Add row"
OnClick="addBtn_Click" />
</ContentTemplate>
</asp:UpdatePanel>
And the code-behind:
private static int counter = 0;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void addBtn_Click(object sender, EventArgs e)
{
counter++;
TextBox txt = new TextBox();
txt.Text = "Text #" + counter.ToString() + " - " +
DateTime.Now.ToString();
place1.Controls.AddAt(place1.Controls.Count - 1, txt);
}
When I click the button it takes ages (it seems compared to the
javascript solution, before the TextBox appears. However as I click
the button once more (in order to theoretically get another row) the
TextBox is only replaced by a new TextBox with updated number and
time.
What am I doing wrong?
