I am using a datalist with checkbox and datalist is in a panel. I am poping the panel by using ajax modal pop-up. When we check the checkbox the checkedchange event is firing. But, when we uncheck the checkbox the event is not firing. It is user control and it is in update panel.

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation
I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.

I have an application that works perfect in IE and FF but when opened in iPhone Safari the checkbox checked and button onclick functions do not fire. I have looked all over the web for the last few days and could not find a solution to this very frustrating problem. I hope someone has encountered this before and knows of a fix.
View 5 RepliesI have a popup which displays two drop down lists, name it : ddl1 and ddl2 and for both of these i have mandatory validation, so if any of these is not provided, callout message will come on submit click.
ddl2 will get populated once any value from ddl1 is selected(selected change event).
Now problem is, suppose without entering any value, i click submit, it is showing select value for ddl1, and when i select a value, the selected change event for ddl1 is not firing, and so ddl2 is not getting loaded.
Selected change event for ddl1 is firing in normal condition, if the callout message is not there.
but after the callout message, if i try to select a value, the event is not firing.
I have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
CODE BEHIND:
[Code]....
[Code]....
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkRDR1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>

Dim checkbox As CheckBox = CType(row.FindControl("chkRDR1"), CheckBox)
I have a simple Textbox for entering password and the checkbox named Show passowrd beside it. Textbox mode is Password by default. These controls are in the table and I am using Update panel on top of the table. My application framework is 2.0 and I am Using ASP.NET 2.0 AJAX Extensions.
Now When i write some text in the textbox and check the Showpassword chekbox then the checkbox event is not getting fired. when Second time i click it then the event is fired and text in the textbox is removed and the textbox mode is set to the SingleLine. This functionality I am achieving by writing a code in the CS File.
When I remove the Update panel then the event is fired correctly everytime, but when usign Update panel and some text in the textbox then i have to check the checkbox twice for the desired functionality.
I have a gridview with one column of checkboxes and other columns with different custom controls. What I want is that when a checkbox is checked an event is triggered which toggles the visibility of other elements in the row .
View 1 RepliesI have a DropDownList for suppliers; suppliers can be active, or inactive. I have a checkbox to toggle between all suppliers, or just active suppliers.
My front code is:
[Code]....
My back code is:
[Code]....
BindDDL() also gets called in page load. The checkbox is unchecked by default, so when I first navigate to the page, only the active suppliers will be selected. When I click the checkbox, the page post posts back, but doesn't change the data in the DropDownList (still only active suppliers).
I've run through the debugger and it's hitting the right if statement, just not updating, and I don't know why. I've tried a Show all/active dropdownlist and event handlers, and neither do what I want them to do. How do I fix this?
Fix: BindDDL() method
I have used below code.
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone"

but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
How to fire the event?
I have a table with 100 cells in it (10x10)
In each cell there is a checkbox. On page load, each checkbox is checked depending on records 0-99 from a database. This works fine.
However, I want to be able to update those 100 records in the database by checking or unchecking the checkboxes.
The update process works ok as I have debugged it, but the problem seems to be that if I check a checkbox, that value (true or false) doesn't get passed to the event handler.
This is the button click event handler that I'm running right now to see if the value is being recognised:
[Code]....
If I tick checkbox zero and click the button, it still comes up as false. What I want to happen is that the DB is updated and when the page loads, the checkboxes are repopulated with the new values from the database.
I have a div in which i have few text boxes and checkboxes, i wrote checkboxchanged event but it is not firing when i check or uncheck the checkbox i set the autopostback property of the checkbox = true but still no result. does any one have idea how to control this scenario.

View 1 RepliesI am using the AJAX ReorderList, and inside the ItemTemplate I have a label and a checkbox. Now when in firefox I am able to change the checkbox checked state, but in IE it won't allow me to do anything with it. Its weird because the checkbox becomes that blue colour like when it gets focus, but it won't put the check in it or call the postback. The ReorderList is inside an UpdatePanel, so that I can monitor when the check changes on its postback. Below is the code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table>
<tr>
<td colspan="2">

View 1 RepliesI have two list boxes and I am using javascript to interchange the items. My problem is, When I press submit button before any changes in the listboxes, it would fire the eventhandler. But when I made any change in these listboxes, a postback happened and the controls became invisible. (There is an html tag and an empty body tag in the source). I know listbox cannot preserve the client side changes to the server. But I could not identify the problem.
