Visual Studio :: How To Change A Value Of A Label Control Using Client Side
Aug 25, 2010
Ho Do i change a value of a label control using client side?
function Test()
{
document.getElementById('Labelj').innerHTML
= 'Your new value';
}
The problem i am having is: I am trying to input the code, but when i type in the javascript, it is not recognising the "innerHTML" value. It is not being promted in my intellisense, therefore the function is not working..is their something i am missing?
I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed.
I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task.
What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.
Has anyone found a tutorial for reporting using VS2010?I would like to create local reports (RDLC) with sub reports or some other solution for master details, preferably with data coming from entity framework 4, but objects data source will do if that isn't possible.
I am using VS2008, SP1. I am unable to put breakpoints in my client side javascript code. Wherever I try to put the breakpoint, I am getting the message: "This is not a valid location to put the breakpoint". I have the js intellisense working fine. I also unchecked the two "Disable Debugging" checkboxes on IE. Due to this problem, I am unable to debug the js in VS 2008.
I am dynamically changing a slider control's maximum value based on an onchange event on a different control. $find("Slider_13").set_Maximum(ordersPerWeek);
This works successfully. The bar's maximum value has changed, however, my slider can now be moved off of the bar, past the maximum value.
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.
So there is a ASP checkboxlist that gets rendered to the table and in the code behind the checkboxes get bound with a label from a code table. I need to display a text box only if a certain checkbox is checked off.
The checkboxlist renders a table which the element retains the ID. I have tried to just get the value of the label when a checkbox is checked and then go from there to create my logic - but I can't seem to be able to grab the value of the label. I have tried the following different ways:
$("#<%chkSomeCheckbox.ClientID> input").next("label").val(); or $("#<%chkSomeCheckbox.ClientID> input").next().val();
I am using the input selector because when I get this first part working, I will need to do some logic on it.
I have a webform that has a lot of controls and a submit button. When a user submits clean data, there is an asp.net label control that displays a "form submitted successfully" message. My problem is that after this successful submission, if the same user enters some invalid value for some fields on the same form and clicks on the submit button, the page still displays the success message along with the asp.net error message for that field (By using the asp.net validation control). My question is how do I get rid of the success message in this scenario? (In this case all I want to display is the client side validation error message). I am not that familiar with javascript.
Here is the markup for the label and button .I tried calling a javascript function on the OnClick event .This disables the success message, but the validation error messages are displayed after a post back.I want to display the validation error messages without a post back.
Every time I press F1 to view the online Help it launches in the Opera browser. I really dislike Opera and only have it installed on my PC for testing purposes. How do I change it to IE?
I have a ModalPopup panel which can be brought up from various different textboxes on my WebForm. In JavaScript when I being up the ModalPopup I set a label.InnerHtml value. That displays the label properly on the screen, but then when I try to read the label's text property in the codebhind, it is the initial value it was. How can I get such a value to be propgated over to the server?
I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.
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..
I have a requirement in which I have to call a JavaScript function in between my server side event and in that JavaScript function code I have to set hidden field value and in next line of that same event i have to use that hidden field value.
For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
I have a form that contains a TextBox. A pop up window will return a value and put it into the TextBox. when this happens, i need to populate another control. I tried "OnChange" but it was not triggered .
