Web Forms :: CheckBoxList Not Executing 'SelectedIndexChanged' On Post Back?
Jan 15, 2010
I am currently experimenting with dynamically populating a CheckBoxList. When a selection is made, a notification is given via the code behind. Below is the code I have been toying with, attempting to work from a simple base.
So far, the list seems to generate just fine, but anytime I check one of the boxes...I am taken back to the same page, with no boxes checked, and without the code behind having executed. If I manually add the asp:listitems to the checkbox, everything seems to work fine.
[b]Default.aspx[/b]
[Code]....
[b]Default.aspx.vb[/b]
[Code]....
I've pulled off this same procedure with DropDownLists.

1) The web application I'm building is a person enters information and the categories are selected by using checkboxes. The input page I have checkboxlist and it enters correctly has a one line to the database. For example, when they check one of the following Red, Blue, Orange and brown, they appear as one line in the database. When they do a search on the individual I need the checkboxes to return that they were selected when it returns information from the database so they update the information or deselect a color or something. Do I need a autopostback on the checkboxlist?
2) Is it possible to have a search page base on checkboxes. For example, the user checks red, and blue. Clicks on the search button. On a gridview every person who checked red and blue when they first entered information will appear in the gridview. Do I need a checkbox result table with a bit field?
I'm not sure which way I should go with this. Just asking for a direction in how I can do this.

I have a little problem with my selectedIndexChanged method of my checkBoxList. For example1. When no items are selected and I check the 3th item, The list returns de 3th item. --> OK2. When the 1st item is checked and I check the 2nd item, the list returns the 1st item, probably because it's checked. --> Not ok, because it must return the 2nd item.

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.

I want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".

Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.
The pages is

I have an Ajax form that lets me dynamically remove rows from a table using the OnComplete AjaxOption. That works great.The problem is that even if I hit "Cancel" on the confirm dialog, it still executes the OnComplete javascript. So the form doesn't post, but it looks like it did to the user (the row is removed from the table).code below:

Beginner question:
I'm not sure if this is specific to Telerik's plug-in I'm trying to use or if it's a 'generic thing' I'm doing wrong ?
I have a RadTextBox:
<telerik:RadTextBox ID="RadTextBox1" Runat="server" name="nameTest"/>
And I have an ASP button that run this code:
Dim a As String = Request.Form("nameTest")
Dim b As String = Request.Form("RadTextBox1")
Both a and b always remain null.
Questions
- How do I get postback values from Rad/components ?
- How do I get postback values from Rad/components when they are in user control ?

In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.

I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);

I have an aspx page for Search Options. There are three aspx Dropdown List Controls that are each bound to seperate data sources. The selection made in the Dropdown control is used in a SQL Query within a GridView data source to display the results list.
When I select an item from the drop down list I get the search result, but I want the drop down list to return to it's initial state after it displays the result, so the next selection made will clear the results list from the first selection. I have tried a number of different approaches, but no success. Seems like this should be easy, but I'm new to coding.
I have found a couple of possibles on the forum, but they didn't work. Not sure if you can make any sense of this, but I'll try to give you something more to go on. All I really want to do is reset the dropdown after it displays the results of the search, which I assume is after a PostBack. Here is what I have tried in the Code Behind or Script.
This for just one of the Dropdown Lists, ID=Practices. I have been trying to make this work for way too long. Also, I have tried it with AutoPostBack set to true but same problem. Currently have a 'Submit" button on the page to initiate the search.
