Web Forms :: Custom Control Error On Load Post Data

Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Web.UI.WebControls.CheckBoxList.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Wzb.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Web Forms :: Hide Divs On The Initial Load And Make Them Appear On A Postback Event?

Dec 1, 2010

I have several divs on an asp page. All of my divs are runat="server". On the initial load of my page I set all the divs visible property to false because I dont want them to appear on the first show. Then, I have a drop down list raising postback events.

On the selected index changed event I am setting the visible property of my divs to true to make them appear on the page. However this does not work.

I discovered that, on the initial load non of my divs are added to the page's html content. So, on a postback event non existing divs can not be made to appear. If all the divs would set to visible = true on the initial load, postback event would work just expected.

Could any one tell me a way to hide divs on the initial load and make them appear on a postback event?

Ajax - Load User Control And Handle Post Back?

Feb 10, 2011

I'm working with asp.net 3.5 c#

I've seen a good few questions like this around but havnt actually come across any articles with the answer (maybe just been unlucky with my research!).

Basically I'm looking to have say 3 links (or buttons) on a page, which in turn will dynamically load a specific user control into an update panel with AJAX.

Then I would like the usercontrol loaded to be capable of handling postback within the update panel (basically no page refreshes) to do its processing and return output.

Does anyone have any pointers to articles/blogs covering this?

I've seen many but non covered handling postbacks from the user control or handling the postbacks within the update panel.

How To Make .net Page Postback When A Control Is Clicked Inside A JQuery Dialog

Oct 18, 2010

I'm having some trouble with jQuery UI. I've created a dialog with jQuery UI: so far, so good. I set up a form inside the jQuery UI dialog and then it's another story. I've written a very simple page to illustrate:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testpage.aspx.cs" Inherits="RiverCascade.testpage" %>
<head runat="server"> [code]....

In the code above, see that I've just imported the jQuery, jQuery UI, and stylesheets and set up a page with a dialog box. There is an asp control button1 outside the dialog box and an asp control button2 inside the dialog box.

When I click on button1, the event handler gets called and all is well. However, when on click on button2, the button inside the jQuery dialog, nothing happens.Why is my web page behaving this way?

Javascript - Post Json Data On Full Postback?

Nov 24, 2010

I wonder if I have any other method but a hidden field to post a JSON object to the server on full postback.

Imagine you have a form (with textboxes, checkboxes, etc) and you need to post a json string when the user post the form. This means, I would post all the form values + the json string but I can't come up with any solution but a hidden field.

C# - How To Make The Content Of The Popup Make A PostBack Only When It's Appeared

Jan 29, 2011

I have a user control is shown through a SimpleModal popup (JQuery), this user control gets some data from database and displays them (the details of a record).

The problem is that this user control makes a round-trip to gets the data every PostBack for the parent page even it's hidden.

I wonder if I could make it gets its data only if the popup is appeared.

I tried to put it inside a Panel with false for Visible property and change it to true when I open the popup, but it stil call Page_Load which gets the data from database!

Here is my requirement -
