enter code hereI have a fancybox popup that has the list of cities on it, and a textbox. Once a user enters another city name into the textbox and clicks "Save", I am able to save the new city into the database, but how can I also reload just the popup, so that the new city appears in the list as well?
My popup is an ASPX page, and all I would have to do is somehow execute the Page_Load event, so that it would display the datagrid with all the cities.
Is there any way I can do that? Somehow reload the popup? PLEASE HELP!!!
Here is the fancybox code that opens my popup:
$(document).ready(
function () {
$("#location").fancybox({
onClosed: function () {
__doPostBack('BodyContent', '');
},
ajax : {
'cache': false,
'titlePosition': 'inside',
'overlayShow': true,
'overlayColor': '#000',
'transitionIn': 'elastic',
'transitionOut': 'elastic'
}
});
});
If I understood well, you should do this: within the server event that gets executed when you close the popup, make sure that you rebind the grid (feed it with the updated data and call its DataBind method again.

I want to capture which button is clicked in page load method of code behind file.
Button is user control button and It does not post back. Since it used by many other forms, I don't want to changes that button.
I tried this
Dim ButtonID As String = Request("btnRefresh.ID")
But it doesn't work.
Is it possible to know without touching in user control and using Javascript?
Thank you
As described here How to check whether ASP.NET button is clicked or not on page load:
The method: Request.Params.Get("__EVENTTARGET"); will work for
CheckBoxes, DropDownLists, LinkButtons, etc.. but this does not work
for Button controls such as Buttons and ImageButtons
But you have a workaround, first of all you have to define a hidden field in the Parent Page. In this field you will store which button inside the user control was clicked using javascript/jquery. And then in your Parent Page Page_Load method you just read the hiddenField.Value property:
JQuery
1) Add listener to every input type submit button:
$(document).ready(function () {
$("input[type=\"submit\"]").on("click", function () {
alert(this.name);
$("#hiddenField1").val(this.name);
});
});
2) [Better one] Add listener to some indentificable div inside the user control and delegate the event to child inputs like this:
$(document).ready(function () {
$("#someElementOfUserControl").on("click", "input[type=\"submit\"]", function () {
alert(this.name);
$("#hiddenField1").val(this.name);
});
});
Javascript
Since everything done with JQuery can be done with Javascript you can do the following (i will not write both samples, just one):
function handleClick(event) {
alert(event.target.name);
document.getElementById("hiddenField1").value = event.target.name;
}
var inputsInUC = document.getElementsByTagName('input');
for (i = 0; i < inputsInUC.length; i++) {
inputsInUC[i].addEventListener('click', handleClick, false);
}
Remember to define this javascript after all your html elements.
EDIT:
Also, for the completeness of the answer let me tell you that the proper way in case you can change the user control behaviour is to use events as described here How do i raise an event in a usercontrol and catch it in mainpage?
I have a page where the user can enter data and on submit, it shows up on a gridview right below it.
How do I prevent double click. I understand I can disable the button but that would defeat the purpose as then, the user cannot enter more information without refreshing the page.
I add a class to all elements I dont want the ability to add a double click
$('.disableDoubleClick').dblclick(function(e){
e.preventDefault();
})
this question has been answered many times, just google disabling double clicking in asp.net
You could always disable the button and then use setTimeout to re-enable the button after second or two: http://jsfiddle.net/BJKy4/
$("#btn").click(function () {
var button = $(this);
button.prop('disabled', true);
setTimeout(function () {
button.prop('disabled', false);
}, 1000);
});
I have a gridView with search and filtering options, it is listing document from SharePoint Library, when i click on the Document name i added a Modal popup to display Documents properties page, if i update Document's title for example and select save, the item is updated but the gridview is still showing the old title, i need to press Search again in order to refresh the values.
the code i use for model popup is:
<script type="text/javascript">
function openModal(url) {
var options = SP.UI.$create_DialogOptions();
options.url = url;
options.dialogReturnValueCallback = Function.createDelegate(null, CloseCallback);
SP.UI.ModalDialog.showModalDialog(options);
}
// Dialog callback
function CloseCallback(result, target) {
if (result === SP.UI.DialogResult.OK) {
SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);
}
}
</script>
what should i do to refresh and bid gridview data when the popup is closed?
on the click of save button, make a serverside call to rebind the gridview. i.e
$(document).ready(function(){
$('id_of_save_button').click(function(){
//ajax call of serverside method to rebind the grid.
});
});
However with asp.net these things become little easy if you use modalPopupExtender that ships with asp.net
Hi for handling sharepoint save event using javascript u can use this function
function PreSaveAction()
{
// write your gride view data bind code
}
Having this div:
<div id="advSearchDialog" style="visibility:hidden;">
<xx:search ID="searchUC" runat="server" />
</div>
And a button:
<input type="button" id="btnAdvSearch" value="Search" />
I turn it into a jQuery dialog, where the button opens the dialog:
$(document).ready(function() {
$('#advSearchDialog').dialog({
autoOpen: false,
height: 500,
width: 600,
modal: true,
bgiframe: true,
title: 'Avanceret søgning',
open: function(type, data) {
$(this).parent().appendTo("form");
}
});
$('#btnAdvSearch').click(function() {
$('#advSearchDialog').css('visibility', 'visible');
$('#advSearchDialog').dialog('open');
});
});
Using ASP.NET, I get a problem.
If I push some other button on the ASP.NET page (inside an update panel), and after that clicks the btnAdvSearch button, nothing happens. Why is that?
Thanks in advance
maybe the partial page refresh removes your click event, hard to say without seeing the whole page.
the solutions to that problem would be using jquery live events

Check the emitted HTML using firebug or somthing similar and you will probably notice that your button is no longer inside the form tags and is at the end of the body tag.
In you're OK button callback you can use something like
dialogBox.appendTo($('#FormIdHere'));
dialogBox is a variable set as so
var dialogBox = $('#DialogDiv').dialog({ autoOpen: false });
This should add your button back into the form.
EDIT:
Here is a code snippet I've recently used (all the code below is fired within an onload function but reasonPostBack must be declared outside the onload function)
var button = $('input.rejectButton');
reasonPostBack = button.attr('onclick');
button.removeAttr('onclick');
var dialogBox = $('#ReasonDiv').dialog({ autoOpen: false, title: 'Please enter a reason', modal: true, bgiframe: true, buttons: { "Ok": function() {
if ($('input.reasonTextBox').val().length > 0) {
$(this).dialog('close');
dialogBox.appendTo($('#theform'));
reasonPostBack();
}
else
{
alert('You must enter a reason for rejection');
}
}
}
});
button.click(function() {
dialogBox.dialog('open');
return false;
});
First i take a reference to the .Net postback with
var reasonPostBack = button.attr('onclick');
and hold it for later then strip the click event from the button to stop the post back ocurring "automatically". I then build the dialog box and add an anonymous function for the OK button, this runs my code to test if there is anything in a text box, if there isn't it simply alerts the user otherwise it;
Closes the div
$(this).dialog('close');
Adds the div back inside the form tags ready for the post back
dialogBox.appendTo($('#theform'));
and then calls the original postback
reasonPostBack();
Finally the last bit of code
button.click(function() {
dialogBox.dialog('open');
return false;
});
adds our own event handler to the .Net button to open the dialog that was instantiated earlier.

I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.
Pressing F5 or physically clicking the browser refresh behaves similarly to navigating away from the page. This is captured in the event window.onunload. Try the snippet example below:
window.onbeforeunload = function (evt) {
var message = 'Are you sure you want to leave?';
if (typeof evt == 'undefined') {
evt = window.event;
}
if (evt) {
evt.returnValue = message;
}
return message;
}
This will capture the refresh and allow you to do something or prompt the user.
Reemember that hotkeys are processed in the client side in the browser. The easiest way to implement this is through javascript.
