In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery. Don't know how to invoke the needed one based on the browsers javascript availability
I have a question about YUI. I am using YUI calendar component in my website project. I insert the codes inside ASP as javascript. (like that [URL]) Now, i am about to hearing your questions, i am answering them immediately. Yes, this link explains how lo localize YUI calendar, but, it does not work for me. Because, it is static. I want to localize it dynamically. It should depend on user's browser language. For example, if the user's browser language is Deutsch, it is supposed to display 'samstag', if it is English, it is supposed to display 'saturday'.
After includeding file.js in ny webpage This script will create a variable within the current javascript context called "Status". This variable can take three values : "On", "Off", "Unknown".How can I read this value on code behind? I am planning to check if the variable is false and if so, make some changes on page.
I would like to know how can I list for every page (child page) selected the number and id of localize component in the current page. I need this to update resources files, a button will be on the master page and when they click on it, they will go to a page which show up every data in the resource file.
I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.
I added some javascript to fill in a dropdown and it works wonderfully. However, when I try to access the value in codebehind to submit the data, the value shows as null. (string strValue = ddlName.SelectedValue;).
i got a problem.. how i can declare template textbox in a datagrid at code behind? i already make a stored procedure and put the update query inside it.. if i declare the textbox inside code behind(.aspx.vb).. there will be an error.. " there is already a component named "txtitem1"component must have a unique name.."
I have an ASCX component that has a lot of javascript declared in a script tag in the ascx itself. I can set breakpoints, and the debugger stops as it should, but the text that is highlighted in the debugger as the "current line" is nowhere near the actual javascript (it is much higher in the rendered file than it should be). I can "wing it" for one or two lines with the real code side-by-side with the "false" line of execution, but I lose all the hover abilities and everything else that makes javascript debugging useful.
I have tried putting the script at the top of my ascx file, but to no avail. I've tried not setting a breakpoint until the entire page is rendered, so that I have to scroll all the way to where the actual lines of code are, and the debugger still stops somewhere way above it.
I have read many different resources but am still not sure if this is possible without using AJAX.
I have a javascript function that loads a div into a modal and says "Loading Please Wait" I have named this funciton loadingModal()
function loadingModal(url) { loadModal(...) }
What I need to do is only trigger this after I have verified that the password and username are correct on the server side so:
btnSubmit_OnClick(object sender EventArgs e) { string usr; string password; if (verify(usr, password)) { ///// TRIGGER JAVASCRIPT HERE LOAD TONS OF SESSION VARIABLES . . . } else Show Error and Definitely Don't ever mention still loading }
I know I could just attach an onclientclick call to the javascript however it would load the loading modal even if it was an invalid username and password
Can I trigger javascript mid execution from the server side?
I have a JavaScript function which i call in the onchange handler of a dropdownlist. If the selected value of dropdownlist is "1" i want to call one function in codebehind. Following is the function in JavaScript:
function GetAdmissionType() { InitComponents(); var type=""; type=document.getElementById(dlAdmissionType.id).value; document.getElementById(hdnAdmissionType.id).value=document.getElementById(dlAdmissionType.id).value; if(type=="1") { } }
If type is 1 then i want to work following code in codebehind
public void LoadSemesters() { //code to load other dropdownlists }
I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
OK, this feels like a question that should be easy to answer, but as with so much mixing of asp.net and jQuery, it's a bit of a nightmare.
What I want to do is be fading a div in and out at various times during the client's viewing of my asp.net page; I fade it out using jQuery's fadeTo() before triggering an UpdatePanel update (to indicate that the data there is not fresh) and I want to fade it in again once the UpdatePanel has been updated. I've gotten as far as updating the UpdatePanel in the codebehind, and this results in the div's content changing... but how do I fade the div back in again?
The way I see it, there are 2 ways; register an event handler on page load to detect when the div's content has been changed and fade it back in, or call a function from the asp.net codebehind when I've updated the div to fade it back in.
In the first case, there doesn't seem to be any event triggered by the div's content changing, so I can't seem to do that. If anyone knows how I could get a client event to trigger when I update the div, that would be a nice solution.
In the second case, I thought that this was what ClientScriptManager was for, but it doesn't quite do what I want. I want to be able to register a particular Javascript function with ClientScriptManager and then tell ClientScriptManager to execute it in the client, from my codebehind. You can't seem to do that. ClientScriptManager.RegisterClientScriptBlock() simply inserts some <script> into the HTML output, rather than calling a function. Presumably this would work if I kept registering things like:
<script>fadeBackIn();</script>
because the Javascript would be immediately evaluated and run, but this feels messy, and that feeling is intensified by the fact that I'd have to keep randomly generating a new unique value for the key argument of ClientScriptManager.RegisterClientScriptBlock(), because it's specifically designed to stop this kind of repeated code. However, I'm struggling to see an alternative.
I'm having some trouble with making use of some AJAX-properties that are normally accessable after I've initialized a scriptmanager.
ie. This work:
[Code]....
Now, I would like to call the javascript-function 'testFunc()' from my ASP.NET Codebehind-file, and here's my problem. I keep getting "Sys is unidentified".codebehind-stuff: ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "testkey", "testFunc();", true);
Does anyone have good idea how to solve this? Much appreciated. Thanks.
I have a modalpopupextender that I want to run based on a timer control. I've tried using the clientregisterscript to run some javascript code to perform a fake click on the link control that initiates the modalpopup, but with no luck. What is the best way to either show the modal dialog programatically or register a jscript that will do this.
