Javascript - Server Side Show JS Alert Box, Doesn't Work When Using Partial Post Back?

Mar 24, 2010

I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown.

public void ShowAlertMessage(String message)
{
string alertScript =
String.Format("alert('{0}');", message);
Page.ClientScript.RegisterStartupScript(this.GetType(), "Key", alertScript, true);
}

What do I need to do so it works on partial post backs?

C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?

Jul 14, 2010

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).

Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?

Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

Page Post Back But Server Click Event Doesn't Fire

Aug 31, 2010

I have a button like this:

<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />

If I write my client function like the following, it works as expected:

function ConfirmSave()
{
return confirm('Confirm?');
}

But I should check, inside the function, for the confirm result, like this:

function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}

Doing this, the page postback but the server click event doesn't fire.

Server Side Caching Doesn't Work With HttpHandler?

Mar 15, 2010

If we use an aspx page with a Caching Profile, the server caches images that are loaded with the aspx page. So if ten clients load the same image through the aspx page (same url), for one client the image is gotten out of the db, for the nine others it is cached.When we use a HttpHandler, this doesn't happen. The image is always fetched from the database. We have tried all different settings without any success. (we have checked this link and have not been able to cache on server side).

AJAX :: Dynamic Image Buttons In GridView Not Doing Partial Post Back?

Sep 9, 2010

watch here:

- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method

This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.

I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.
