View 6 RepliesI have a simple javascipt which enables/disables some checkboxes when another checkbox ticked/unticked. This works fine, however, in some instances when by page is loaded my code behind disables the same check boxes. When this happenes my original check box nolonger seems to have any influence in enableing or disabling - there is no error and all the elements seem to be found by the javascript - it just doesn't enable/disable the checkboxes.
View 5 RepliesI have a checkbox which in some cases may be disabled and checked using javascript, i.e:
var cbTest = document.getElementById("CheckBoxTest");
cbTest.disabled = true;
cbTest.checked = true;
However, when sending a postback, CheckBoxTest.Checked is false on the server side.
Is it possible to disable the checkbox and still have the server side recognize it as checked?
I'm trying to write code that will disable submit button (or all submit buttons) on the page to avoid double postback.I thought of generating my own postback javascript function (and inject postback javascript using GetPostbackEventReference) but maybe there are some better ways to do this? Or maybe there is some other way to avoid double postbacks?
View 4 RepliesI've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.
$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));

I have an input box that I don't want postback to occur on someone striking the enter key
I want the javascript event to take place instead.
<input
type="text"
id="addressInput"
onkeydown="inputenter()"
autopostback="false"/>
function inputenter() {
if (event.keyCode == 13) {
seachLocations();
return false;
}
else {
return false;
}
}
I have an application that is supposed to accept checks. The user has 2 radio buttons. The first radio button has a drop down list associated with it which contains the masked numbers of their previously used checking accounts.
The second radio button has three text boxes and an image of a check associated with it.
When a user hits this page, the three text boxes and the check image associated with the second radio button are disabled. Then, if the user decides he/she wants to use a new checking account, they can click the second radio button and that fires the Javascript that enables the three check boxes and the image of the check associated with that second radio button. If they click on the first radio button, it will re-disable the text boxes and hide the check image associated with the second radio button.
The problem happens when I do my server side validation. After validating all text fields, if there is a problem, I just fall out of the bottom of the code, the page posts back and the labels above the offending text fields show an error message.
One caveat: The Javascript that is supposed to fire on the OnClick event for the first radio button fires and the text fields for the second radio button are disabled. The user can click on the second radio button and the fields will enable, but this is very clunky.
Here's the enable code where I am injecting the Javascript:
Private Sub JavascriptInject()
Dim sEnableControls As String
Dim sDisableControls As String

How can I do this? tryed different methods found online but all incomplete or wrong.
View 1 RepliesI have multiple update panels with various asp buttons on a single page. I want to disable the buttons which caused the postback in update panel untill it completes.
Is there a way to avoid using a third party control for this? through JQuery or any other method ?
I have a simple asp:RadioButtonList within a form tag but for some reason it isn't keeping it's value on postback

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
Is there a way to have a dropdownlist disabled if the user checks a checkbox? Is there a tutorial that you can point me to?

<asp:TemplateField>
<ItemTemplate>

There is a calendar control on my page and I need the selected date to remain selected after I hit this button. Right now if I hit the button it refreshes the whole page and sets the calendar's selected day back to date.
How to disable postback on page..
View 2 RepliesI have a master page containing menu items and if i click on any menu item then postback happens(it's not an asynchronous postback) that page loads in the content area. Now, if the page has taken some time to load and the user again clicks some other menu, then at some cases, it is crashing. So what i want to do is when postback is happening, I want to restrict the user to click anywhere on the master page or content page. We have achieved this on asynchronous postback.... But cant find a solution during postback.

I have a checkbox placed inside a gridview:
<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>
For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.
Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.
How could I disable the autopostback of the checkbox during the listview item changed.
