AJAX :: Dynamic Client-side Content / Getting An "object Expected" Error From An OnClick Event From A HTML Control?
Feb 6, 2010
Is it possible to use JavaScript passed by Ajax on the client-side? I am getting an "object expected" error from an onClick event from a HTML control that is passed with the JS. The controls and JS work when the page is rendered on the server.
I have created dynamic control with both server and client side events.. if i set client side event server side event is not firing.. I have created the link button which will validate and do some necessary actions.. Validation is working but click event of link button is not firing .. if we remove the client side event , server side event is firing.. how to avoid this.. I want both events..
However, ever since I have introduced the notion of content place holders (from a master page), I am repeated getting the Object Expected error.Now I understand why this is happening, asp.net is amending the control names to take into account the CPH i.e. $('#ctl00_ContentPlaceHolder1_radBuyer').attr('checked', true);
How do I go about reslving this issue, effectively 'renaming' my asp.net controls to take this into account?
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
I've got a few ComboBoxes on a page which worked fine before. I can't recall making any changes to the form but now I get an "Object Expected" javascript error when the page loads and the comboxes don't load/work.
On debugging from IE, the highlighted error is in MicrosoftAjax.js in the piece of code
I know this topic has been posted before but I'm stuck on it still.I've placed creating of dynamic control on Page_Load but the event isn't firing.On my asp page, i have <asp:PlaceHolder ID="test" runat="server/>On my code behind, I have private display method.
private void DisplayButton() { LinkButton btn = new LinkButton(); btn.ID="unit_1";
I have the following client side code in .aspx page within a datalist itemtemplate that takes questions from the database like this:
[Code]....
The output is like:
1) What is your age group? - Option 1 - Option 2 - Option 3 - Option 4
The ID's of the radio buttons are dynamic ("Q" & QuestionID). If there is no answer to a question then the GetVisible function returns false and the containing panel is hidden.
I have been trying to get rid of the html and replace these with asp:radiobuttons but it is not possible to set id's from databinding.. only simply. I was trying something like:
I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I m using site login Control in my login.ascx file and disaplaying login control in Div so if there is login link in page and i click on that then Login Div will popup which is site login.May i know how can handle error like username or password is incorrect on client side instead server side?
I've created a ScriptService / ScriptMethod that uses a custom class as an input parameter but can't figure out how to create an instance of the object on the client side.I thought that when I used ScriptManager and Ajax before the ScriptManager registered my server side classes for me or am I completely mistaken?
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:
I want to handle the OnClick event on the client side with javascript, i tried using OnSelectionChanged which 's triggering event handler that's being handled in the code behind(.cs). Basically, my requirement is when user clicks on a particular date, i want to pass the date selected value to a javascript function to implement other part of the webpage functionality.How do I handle the onClick client side?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript"> function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
[code]... Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I have an existing GridView which contains the field "partner name". It is sortable by partner name.Now I need to change the Partner Name field and in some condition make it clickable and alert() something.
I am trying to get my ListView to select the item that was clicked.
I have it working with a CommandButton in the listViewItem, but I would like to have the item select when the user clicks anywhere on the row.
I need to somehow PostBack or otherwise get the ListView to return to the server and re-bind with data. I just don't know enough about client-side script to get this done.
This is the HTML client-side code of interest. Specifically, the onClick event.
I got this error "object reference not set to an instance of an object" when i want to display the values of dynamic generated drop down lists by pressing a button to show the values in Listitem.
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages: [CODE] CmsContactUsContent += string.Format(" "" + "" + "
I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.
