Ajax panel update during the middle of a function C# ASP.net site.
This is the button click. I would like to update LbError.Text to "" before the rest of the function continues. This is my current code.
protected void BUpload_Click(object sender, EventArgs e)
{
LbError.Text = "";
UpdatePanel1.Update(); //// need it to update here before it moves on
but it waits till the end to update the lablel
Exicute functions.....
.......
.......
}
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<contenttemplate>
<asp:Label ID="LbError" runat="server" CssClass="failureNotification" Text=""></asp:Label>
<br /><br />
<br /><br />
<asp:TextBox ID="NewData" runat="server"></asp:TextBox><br />
then click
<asp:Button ID="BUpload" runat="server" Text="Upload New Data"
onclick="BUpload_Click"/><br />
Things I have tried include have another UpdatePanel just and same results. Any help would be greatly appreciated.
You can use PageRequestManager to do the job. Here's working sample. Markup:
<asp:ScriptManager ID="sm" runat="server" />
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(InitializeRequest);
function InitializeRequest(sender, args) {
$get('LbError').textContent = '';
}
</script>
<asp:Label ID="LbError" runat="server" CssClass="failureNotification" Text="This is a label"></asp:Label>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<br />
then click
<asp:Button ID="BUpload" runat="server" Text="Upload New Data"
OnClick="BUpload_Click" /><br />
<asp:Label ID="Label1" runat="server" CssClass="failureNotification" Text=""></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
And code behind C#:
protected void BUpload_Click(object sender, EventArgs e)
{
UpdatePanel1.Update();
System.Threading.Thread.Sleep(5000);
Label1.Text = "Done";
}
