MVC :how To Use A Simple Javascript Code Within The Click Event Of The Checkbox
Aug 2, 2010
Here is my situation. I have inherited an MVC 2 application. I am learning MVC 2 on the fly with this application. I am trying to validate a checkbox by doing this: Grey out the submit button until the user clicks on the "checkbox" then the submit button is enabled. 1st question: Where do I place the code to make this happen? 2nd Question: How do I go about doing what I explained? I wanted to use a simple javascript code within the click event of the checkbox but I don't see this in MVC 2.
my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.
Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.
I have a webform with 2 listboxes and 2 checkboxes... When I check checkbox1 I want listbox1 to be disabled and checkbox2 to be disabled. Similarly, when I check checkbox2 I want listbox2 to be disabled and checkbox1 to be disabled. The code does not show any errors; however, when I run the Page everything appears as it is supposed to but when I check the boxes, nothing happens. What am I missing that will link the code on the .aspx.vb page to the objects on the .aspx page and make them work together?
From a user perspective, I can list of users in a grid with some associated checkboxes. When I click on a checkbox, I want to update the database straight away. No buttons involved.
I am new to MVC.
I am trying to work out if I can do this by using a BeginForm that wraps around each checkbox. It appears not, but how can clicking on a checkbox cause a POST?
Or maybe I can use a JQuery click or change event on the Checkbox? But in a grid the id for the checkbox is repeated, and I cannot get it to work even with 1 row of data.
The code below does not work. If I can get it to work, I need to send an AJAX post to call the method on the controller with the Model.UserId and the checkbox value;
I'm implenting a functionality of inbox where i have a GridView and code as follows:
[code]....
But here even if i select a checkbox onclick event gets fired. i dont want the checkbox to fire this event. It should just act for selection of rows. What shall I do?
In my user control I have gridview, and this grid is created programmatically, using Itemplate. In InstantiateIn methods I have this code.
Select Case _templateType Case ListItemType.Header Dim linkButton As New LinkButton [code]....
I want to wired up Click event to this LinkButton, and use this event in code behind.This is constructor of GridViewTemplate how implements ITemplate
Public Sub New(ByVal type As ListItemType, ByVal colname As String, Optional ByVal infoType As String = "") 'Stores the template type. _templateType = type 'Stores the column na [code]....
and i have this call from user control:bfield.ItemTemplate = New GridViewTemplate(ListItemType.Item, dt.Columns(col).ColumnName, "label")
where is Dim bfield As TemplateField = New TemplateField()
i have datalist and on button click event i check the checkbox is checked or notfor this my code is
<asp:DataList runat="server" ID="dlstproductsize"> <ItemTemplate> <input type="checkbox" value="<%#eval("size_id")%>" id="chksize" runat="server" /> <%#Eval("name")%> </ItemTemplate> </asp:DataList> If chkallowsize.Checked = True Then For Each item In dlstproductsize.Items If (CType(item.FindControl("chksize"), HtmlInputCheckBox)).Checked = True Then ocommon.ProductMapingInsert(uniq_id.Text, CType(item.FindControl("chksize"), HtmlInputCheckBox).Value) End If Next End If
i get the error like object reference not set to the object
How can I add a click event to my div from code behind?
Im looking upon clicking on the div to be greeted by a message box with would you like to delete this and a yes or no within the box?
All from the code behind:
while (reader.Read()) { System.Web.UI.HtmlControls.HtmlGenericControl div = new System.Web.UI.HtmlControls.HtmlGenericControl("div"); div.Attributes["class"] = "test";
I am having gridview and i have check box for each row. There are 2 buttons ,accept and reject outside the gridview. If I click accept button, all the checked rows fields value should change to accept and if i click reject button all the checked rows column value should change to reject. There are 3 columns only one column will change.
I have a set of accordian divs (powered by the prototype library) in an asp.net page. I would like to save the state of the accordian, so when a postback event occurs, the same div is open rather than reloading the page entirely and opening the default div.
My plan was to set a page control value with the ID of the open div using the div's toggler click event function, and then fire a click event after postback calling that same div (using the value of the control holding the div ID) as the target. I'm not sure how to fire a javascript click event from vb.net however, and this sure seems like a lame workaround.
1) can you tell me how to fire a javascript click event from the vb.net codebehind page
I'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:
Button b = new Button(); b.onClick = otherClickEvent();
but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.
i m using asp.net Usercontrols How to show alert msgbox if user doesn't select atleast minimun 1 checkbox from asp.net checkboxes
if i have disabled some checkboxes on page load event then after user forgot to check checkboxes and click on button then still msgbox will popup "you haven't select checkboxes"
edit my this code ...to show msg box on button click event if i have disabled checkboxes and if user haven't select any of the checkbox
I currently have this working but it requires me to have a static method as the method called in the code behind. I would like to be able to access some member variables that can't be static.
EDIT: Let me clarify, I'm looking to edit a value in one of the user controls on the page based on the button click. I am holding the user controls in a list on the page and using the parameters passed through the javascript to find the user control that I want to update and modify the value there.
It currently looks like this:
Javascript:
function incrementCompletes(obj) { var firstParameter = $(obj).parents('.parentClass1').find('.childClass1').html(); var secondParameter = $(obj).parents('.parentClass2').find('.childClass2').html();
[Code]....
I would like to find a solution that does not require the method called to be static.
How to check all asp.net checkboxes on single asp.net button click event
if i have 45 checkboxes inside panel1 i want on button click event all the checkboxes will be checked and on another button click event all checkboxes will be unchecked...
i place the onClick event in asp buttons. but it is showing error like
Too many characters in character literal
my code is
<asp:Button ID="Button1" runat="server" Text="Button" onClick="alert('The button was clicked.');" />
actually my requirement is when i click on the button i want to display some message and when we press ok then it is redirect to another page is it possible
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?
On one page, I have 2 buttons. One that says Clock-in and the other says Clock-out. As of this moment, the application will allow you to click on the clock-in button without having clocked out the previous day and will allow you to click the clock-out without being clocked in. If a user is clocked in and they click the clock-in button again, I would like an alert to pop-up that would say "you must clock out before you can clock in". And if the user clicks clock-out without being clocked in, it should say "you must clock in before you can clock out". I am using VB in the code behind and SQL Server 2005. My current button click events are below:
