Upgrade problem or possible error

Question

I have TextBox(multi-line) and Labelin UpdatePanelwhich I update using javascript__doPostBack(upEditReminder,id);

I then set both the text Labeland TextBoxthe current DateTime.

protected void upReminder_Onload(object sender, EventArgs e)
{
    lbTest.Text = DateTime.Now.ToString();
    tbReminder.Text = DateTime.Now.ToString();

The problem is that it is Labelupdated, but the TextBoxdate is updated only once, when the page loads, but not when it is fired __doPostBack(upEditReminder,id);. I can’t understand what the problem is.

I also tried textarea runat="server", but still have the same problem.

Your help is greatly appreciated.

Answer 1

It worked for me ... is it different from what you are doing?

aspx code snippet:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" OnLoad="UpdatePanel">
    <ContentTemplate>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox>
    </ContentTemplate>
</asp:UpdatePanel>
<a href="#" onclick="__doPostBack('UpdatePanel1','');">Update</a>

codebehind snippet:

protected void UpdatePanel(object sender, EventArgs e)
{
    Label1.Text = DateTime.Now.ToString();
    TextBox1.Text = DateTime.Now.ToString();
}

"" UpdatePanel, ajax, .
