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
}

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 wrote below code for Collapse/Expand some section. It is working fine. Finally If I click "Save" button and I am re-loading page again in asp.net. So then sections are going default Colleapse again. I need them back to expand. How can I do that?
$(function() {
$('tr.subCategory')
.css("cursor", "pointer")
.attr("title", "Click to expand/collapse")
.click(function() {
$(this).siblings('.RegText-' + this.id).toggle();
});
$('tr[#class^=RegText-]').hide().children('td');
})
You can save state using:
URL hash: mysite.com#a=1,b=2 ...or however you want to record your state.
Cookies
Window.name
On reload, check for the recorded state, parse it and re-execute it in your code.
Edit:
When you execute something that changes in the UI you need to record this action somewhere (i.e. Panel A is open), in some sort of code. It could be name, value pairs (ID,STATE|ID,STATE..etc) in a string or whatever you choose. You then need to program a mechanism that takes this "saved state" information and re-initializes the UI back to where it was.
Once you've accomplished a way to represent and re-initialize the state, you have to consider how you'll save and retrieve it.
You can save it is a cookie, if it's not too big. When the page loads, check for the cookie and parse the data and run your re-initialization routine to restore the UI.
Another persistent place to stash data is in window.name, which can hold a string of up to 2mb. Same deal as a cookie.
The third method is to store the state information in the URL: document.location = document.location + "#" + stateData. You can then parse what's in the URL to grab your state data.
The "url/hash" method is becoming the preferred technique as it allows bookmarking and is a new specification to allow search-bots to read ajax-based sites easily.
See: http://code.google.com/intl/sv-SE/web/ajaxcrawling/docs/specification.html
If you are using update panels you can make us of the fact that jQuery's $(document).ready is called only on the initial load and ASP.NET AJAX's pageLoad() is called for every postback. You could collapse your section in $(document).ready so it's initially hidden and then assign the click handler in pageLoad() so users can still collapse it again if they need to after the save.
$(document).ready(function() {{
$('tr[#class^=RegText-]').hide().children('td');
}});
function pageLoad() {
$('tr.subCategory').click(function() {
$(this).siblings('.RegText-' + this.id).toggle();
});
}
you could use an hidden div field, and modify your js to set the hidden text to the id of the expanded field on click. Your function could check the value of the hidden text and show the field that matches the hidden text id.
in your page:
<div class="hidden" style="display:none;" />
in your .js
$(function() {
$('tr.subCategory')
.css("cursor", "pointer")
.attr("title", "Click to expand/collapse")
.click(function() {
$(this).siblings('.RegText-' + this.id).toggle();
$('.hidden').text(this.id); // set the hidden field to the id shown
});
$('tr[#class^=RegText-]').hide().children('td');
$('#' + $('.hidden').text() + ''').show(); // show the id set in hidden field
})
I am developing an web application. In this i provided a functionality means "autocomplete textbox". In this control, I need to show up 4 columns whenever user press keys in textbox, i need to collect these keys and send it to the service which will give us result as xml. then i convert xml to dataset and binded with datagird. for this i used jquery. after the result displayed ( i mean the result in datagrid which is placed in div), then i need to hide the div when the user clicks outside of the div or press escape key...
for this i used onblur event. but, when i click on the result then, i could not fire the click event for the div..
here is my jquery events...
function showList() {
if(document.getElementById("txt1").value.length > 3) {
$("#divList").hide("slow");
$("#divLoading").show();
$.ajax({
type : "POST",
url : "ajaxServerPage.aspx?streetname=" + document.getElementById("txt1").value,
success : function(responseText) {
$("#divLoading").hide();
$("#divList").show();
$('#divList').html(responseText);
//add button click events for buttons which are placed in table
$("#dataGridStreet .rowStyle").click(function(e) {
//Open_ModifyPopup($(this).attr("id"));
clickedRow($(this));
});
} // function(responseText)
});
}
}
How should I do this?
Thanks
Why reinvent the wheel: How about using a plugin to do it for you?
I have an asp.net aspx page and on that page I have a hidden input field with and id of paneIndex. However, when I load the page, the alert shows index 1 which is correct on the first load, but if I open up pane 3 for example, the alert shows 1 still. Am I doing something wrong?
In a Custom.js file, I have the following code:
$(document).ready(function() {
$("#accordion").accordion({
active: 1,
collapsible: true,
autoHeight: false,
change: function(event, ui) {
var activeIndex = $("#accordion").accordion('option', 'active');
$("#paneIndex").val(activeIndex);
//alert(activeIndex);
}
});
});
In my server side button click, I have the following code:
string activeIndex = Request.Form["paneIndex"];
string script = string.Format(#"<script type=""text/javascript"">var paneIndex =
{0};</script>", activeIndex);
if(!ClientScript.IsStartupScriptRegistered("JSScript"))
ClientScript.RegisterStartupScript(this.GetType(),"JSScript", script);
I have just tested the jquery script locally here and it works fine for me without form submission / postback.
Therefore I assume your issue is related to the form submission / activeIndex variable not being set correctly.
If you use asp.net, do you need to submit the form instead of using postbacks?
I always try to do a postback to the server if possible instead of form submission.
If you use Visual Studio you could also try to set a breakpoint on the server-side code and investigate the Request.Forms collection contains the correct variables after submission.
I have the following JQuery code in a external JS file linked into a
usercontrol in .Net 1.1 webapp.
The usercontrol is a timesheet.
When the page loads it calls MonthChange and works fine in one page.
But now I want to load the timesheet/usercontrol into aother
webpage that pops up a in a new browser window for printing.
Problem is my MonthChange is not firing.
Any ideas why???
$(function() {
MonthChange();
//TestData();
$('[class^=TSGridTB]').blur(function() {
var day = GetDay($(this).attr('id'));
var date = GetRowDate(day);
var bgcolor = GetInputFieldColor(date, false);
$(this).css("background-color", bgcolor);
$(this).parent().css("background-color", bgcolor);
//CalcHours($(this).get(0));
});
$('[class^=TSGridTB]').focus(function() {
var day = GetDay($(this).attr('id'));
var date = GetRowDate(day);
var bgcolor = GetInputFieldColor(date, true);
$(this).css("background-color", bgcolor);
$(this).parent().css("background-color", bgcolor);
});
$('[id$=lstMonth]').change(function() {
MonthChange();
});
});
without seeing further code, ensure that the selector is correct for the control in the new page.
The problem may be that the DOM has changed for the new page/window and JQuery does not yet know about it.
The change event
fires when a control loses the input
focus and its value has been modified
since gaining focus.
You might want to use the live event:
Binds a handler to an event (like
click) for all current - and future -
matched element.
When you bind a "live" event it will
bind to all current and future
elements on the page (using event
delegation). For example if you bound
a live click to all "li" elements on
the page then added another li at a
later time - that click event would
continue to work for the new element
(this is not the case with bind which
must be re-bound on all new elements).
Did you make sure that the new web page has jQuery script includes?
ensure you're using:
$(document).ready(
);
around your entire code block. The $ alone often does not do the trick.
