I'm trying to seamlessly log in the user without prompting for credentials as part of a <asp:Wizard> process. My strategy is to handle the NextButtonClick event and login the user in code. I already have the user's credentials saved in session variablesIs it possible to login a user in code? Will a hidden <asp:Login> control behind the scenes be required?
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 this method, but the javascript never executes:
Protected Sub Logout(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LoginCancelEventArgs) FormsAuthentication.SignOut() Session.Clear() Me.Page.ClientScript.RegisterStartupScript(Me.GetType(), "alertScript", "facebook_logout();", True) End Sub
The first time the page renders the script is executed. If I click the button to cause a postback it doesn't execute again. Is there a way to make it execute the scripts again?
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?
Basically i have two asp.net buttons on my asp.net page as follow:
[Code]....
and this is the code behand fo btnSave onclick event:
[Code]....
and this is the code behand of btnPreviwe onclick event:
[Code]....
as you can see, when the btnSave is clicked, it is programmatically clikced the btnPrevew first, and btnPreview registers and fires the required JavaScript. But actually once the btnSave clicked, it does go to the btnPreview_OnClick event, but for some unknow reasons, the javascript in btnPreview_OnClick doesnt work, however, when i just put cstext2.Append("alert('hi')" instead of cstext2.Append("'SaveSignature()'", the javascript does executed, and also if i modifed the asp.net code for btnPreview to this, it works too.
I have a content page that displays search criteria in a div. I would like to hide the criteria div when results are returned, but keep it visible if no results are found. I have code in the DataBound event for the gridview that displays the number of rows returned from the query which works fine. To show the search criteria, I have a RegisterStartupScript which calls the javascript function to show the div. Even though the RegisterStartupScript code is executed, the javascript never runs (I put an alert in the function that never fired). Is this a lifecycle timing issue? I just don't see how I can register the javascript earlier in the page lifecycle if it is. I would think this is a very common requirement. Sub Master:
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 only want to execute this JavaScript function runEx() if publicVarFromCodeBehind != "abc".
I am setting the publicVarFromCodeBehind = "abc" in the Page_Load event but anyway the runEx() function is executing. I wonder how this works and how to prevent runEx() from executing though I need to catch the logic from C# and pass on the variable to the JavaScript.
I have downloaded a jquery tool which creates overlay windows so here is the code which I want to trigger by calling a javascript function instead of a button or link.
The CSS
[Code]....
The HTML note the overlay is executing when i click the button i want this to be triggered on javascript function)
[Code]....
[Code]....
All i want to do is call a function lets say "ShowOverlay()" from my code behind using ClientRegisterScript() and it should do the same as it is doing on button.
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.
