Web Forms :: Onclick To Both Code Behind And JavaScript?
Dec 30, 2010
I have a server control button , btnProcessTransaction, which calls a method to run a stored procedure in the DB, I need to add another onclick to call a javaSCript funtion , how can i do both calls for the same button. Here is my code before applying the javaScript call>
I wanted to disable a button after it is clicked and at the same time fire the post back event to generate a report. My first set of code did not work because soon after the button is disabled the page won't submit/post back. here's the first set of code which was not implemented. the onclientclick calls a javascript function which has these lines
its not working from client side alone after I disable the code behind attributes.add but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?
I have an imagemap with 3 hotspots. One downloads a .pdf, the other two redirect to two other websites. Now they want to be able to track who downloads the .pdf file with our reporting program (VisiStat). To do that, I have to add some code to the OnClick event of the .pdf hotspot.
[Code]....
The code in the "VSLT('MyFile.pdf')" can be any name, that's what shows up in the reports.
I've tried doing this with a code behind OnClick event handler, but it can't see the javascript included in the asp page:
[Code]....
And I'm guessing that's where the VSLT code is at. I tried moving my code inline in the asp page, but it always says my sub is not a member of the page. What am I doing wrong? It seems like I'm just calling it or referencing it wrong.
The OnClick_Next is reloading the whole page, which means the Do Until statement fires everytime because counter always equals lastID (they both start as zero).
So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.
I Simply drag a button from the toolbar onto a new page with a master page and a title, double click it so that I enter the Button1_Click function and sets a breakpoint and add some random code. The breakpoint nor the code never fires. I've tried this on several different pages and controllers, but with the same results: The page reloads, but no code is run. I Have Tried:
Ive tried with three different webbrowsers with all plugins disabled. I've tried to turn of Causes Validation, - Nothing changes. I've tried to clean and Rebuild the project, - Still nothing. I've tried to create a whole new project, -Does'nt work there either. Other Information: A RadioButtonList OnDatabound Event works, but whenever i try to do a Button or ImageButton click event the code for the event never fires. Ive programmed several webapplications in other versions of visual studio and ASP.NET but I have never encountered this problem before.
Breakpoints work in other parts of the code and the compile settings is set to DEBUG.
* Visual Studio 2010 * ASP.NET 4 * MVC 2.
Am I supposed to file a bug report or does anyone out there have a solution?
<asp:RadioButton GroupName="grpAssoc" ID="rbtEvery" runat="server" Text="Everyone" onclick="return doChangeAssociationType(0);" AutoPostBack="True" oncheckedchanged="rbtEvery_CheckedChanged" /> but oncheckedchanged="rbtEvery_CheckedChanged" not firing even javascript function returns true
If I use both onclick() and onClientClick() can I make sure that server side will be called only after client side function returns TRUE or vice versa?
For example:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Import Namespace="System.Xml" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <% protected void save_n_display(object sender, EventArgs e) { // This must be called when validate() returns true... } %> <asp:Button ID="Button1" OnClientClick="validate()" onClick="save_n _display" "Text="Check" runat="server" /> <script type="text/javascript" language="javascript"> function validate() // client side Validation is done { } </script>
So can I use onclick() and onClientClick() or do I need something different for this? I even tried passing variables from javascript to asp functions so when validate returns true then save_n _display will be called.
Void button has a confirm box after receiving true, expecting running another button's click event however, Void2_Button_Click not run, where is wrong?
protected void Void2_Button_Click(object sender, EventArgs e) { // do something } Void_Button.Attributes.Add("onclick", "var agree=confirm('Confirm to void?'); if (agree){document.getElementById('Void2_Button').click();}");
On Firefox it does what it supposed to. But it won't work on IE or Chrome.I know there are some questions on the subject here, but they haven't helped me. I'm guessing it's more specific since it envolves ASP.NET postback.
Basically when a user clicks a button I have a javascript code that runs that displays the hidden DIV, my question is how do I make it so when the users click it executes the SQL code (which is already written to select the data) and then it displays it in the DIV that I want. Would the only way to do this be add a label to the DIV and then use LabelName.Text to populate it or can this be accomplished some other way? I am using Visual Studio 2008 and coding in c#.
I have 2 textboxes which has default values in forecolor:#999999. If I click on the textbox, the default value should clear and the forecolor should change to black. I mean, like watermarking. But I am not using any Ajax.
i am working in MVC & want to add a javascript file only in when the 'onclick' event is fired for actionlink... ie. by default a javascript file is not included in my project... but when the actionlink button is clicked then only the javascript file shud be added..
However the onclick does not fire the ListView.Command or ListView.SelectedIndexChanging event? If I add a button with CommandName="Select" it works as expected? The POST data is the same!
i have a navigation bar made up of ImageButtons that have their image swapped out on mouse over and back on mouse out. i used this code in the Page_Load handler to do this:
Note: The answer marked as the answer, answers the questions in the Title. However, my underlying problem, using type ahead dropdowns, is solved by moving to IE8.
I have a drop down list that when I CLICK a NEW selection I want to cause a postback ("this.form.submit()") But only if the click on the dropdown list just changed the selection.
Note that OnChange will NOT work because when the selection is changed by the keyboard I would not want to postback because it is a type ahead dropdown list.
I also suppose I could use OnChange and check if the change was caused by the mouse.
Maybe if we can come up with both solutions and i'll see which works better?
EDIT: More information:
AutoPostback = true; will not work. (don't want it to post back when the selection is changed by the keyboard)
onBlur = doPostBack; I tried this, but the result is not optimal. The user has to click off the ddl after making a selection with the mouse.
Another way to state what I want to do, i think, is do a postback when both the OnChange and OnClick events fire at the same time.
