I have a asp.net web forms app with update panels.
and its also in a listview and I dont know if that matters or not.
I have the following Javascript..
<script lang="javascript" type="text/javascript">
function pageLoad(sender, args)
{
$(document).ready(function () {
$('textarea.epop').live('click', test);
});
function tes(event)
{
var btn = $(this);
alert(btn.val());
$('#editortext').val(btn.val());
var dialog = $('#edialog').dialog({
modal: true,
width:'auto',
resizable: false,
buttons: {
'OK': function() {
alert($('#editortext').val());
alert(btn.val());
btn.val($('#editortext').val());
$('#editortext').val("");
$(this).dialog('close');
return false;
}
}
});
// Move the dialog back into the <form> element
dialog.parent().appendTo(jQuery("form:first"));
$('#edialog').dialog('open');
return false;
}
}
</script>
Then I have this in the html body..
<div id="edialog" title="Edit SQL" style="display: none">
<label for="editortext">
SQL Query:</label>
<textarea rows="20" cols="100" id="editortext" class="editortext"></textarea>
</div>
and then in one of my list items in my list view wich is inside a update panel. I have..
<asp:TextBox ID='txtSQLQuery' CssClass="epop" TextMode="multiline" Columns="50" Rows="5" runat="server" Text='<%# Eval("SQLQuery") %>' />
code works perfect the first time with no post back.
but say I change the selection, and then a auto postback happens...
then the code no longer sets the text.. when you click ok..
using alerts I can see that its actually still referencing the old value and not the new current displayed value which seemed to invoke the click.
At this point I am stumped..
If you have your controls inside updatepanel and the update panel is set to updatemode ="condicional" you probably have to invoke updatePanel.update() from your server side code to update values.
Another thing that often happens is that the update panel and jquery are not best friends, so it will be better writing or initialize your code like this:
$(document).ready(function () {
$('textarea.epop').live('click', function(e){
test();
});
});
// register again after postback's
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {
$('textarea.epop').live('click', function(e){
test();
});
})

I have used page1.aspx & page2.aspx.
In page1.aspx I have used following code,
<div id="resultdiv" >
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
In page2.aspx, i have load the page1.aspx page on the div of page2.aspx page.
the code is,
<script type="text/javascript" >
$(document).ready(function () {
$('#result').load('page1.aspx #resultdiv');
});
<div id="result">
my question is, how to access page1.aspx controls(textbox) from page2.aspx.
pls clarify my doubt. i'm new to jquery.
i dont know what you want to ask but whatever i understand i think you want to get controls of another page....
you can try this below code
function load_controls()
{
$.get("page1.aspx", function( data ) {
$("#result" ).html(data);
});
}
and then call this function where ever you want....hope will help you and if you have any query then just put comment....
You can do something like below in page2.aspx:
<script>
function save() {
$('#resultdiv input').each(function () {
alert($(this).val());
});
}
</script>
I am trying to show a loading div on button click, but it is not working at the moment.
Javascript :
<script type="text/javascript">
$(document).ready(function (e) {
$('#BtnSend').click(function () {
$('#<%= loading.ClientID %>').toggle("slow");
});
});
</script>
Div:
<div id="loading" class="Loading" runat="server" visible="false">
<div class="loadingImg">
<img src="../Images/loading.gif" alt="loading" />
</div>
</div>
button:
<asp:Button ID="BtnSend" runat="server" Text="SEND"
onclick="BtnSend_Click" CssClass="pressbutton2" Height="36px" ClientIDMode="Static" />
Also how can I call the same javascript code in the jsfiddle above within code (c#)?
You have to select jQuery version from left menu, jsFiddle does not support to interpret asp.net code and generate html as asp.net engine do.
Live Demo
$(document).ready(function (e) {
$('#BtnSend').click(function () {
$('#loading').slideToggle("slow");
});
});
If you are trying to do same in asp.net and your BtnSend is server control which does not have ClientIDMode set to static then you will need to use ClientID to bind event.
$(document).ready(function (e) {
$('#<%= BtnSend %>').click(function () {
$('#<%= loading.ClientID %>').slideToggle("slow");
});
});
The ClientID value is set to the value of the ID property. If the
control is a naming container, the control is used as the top of the
hierarchy of naming containers for any controls that it contains, Reference.
I have the below JQuery script
<script type="text/javascript">
$(function() {
$("#no-email-popup").dialog(
{
autoOpen: false,
buttons: {
"ok": function() {
alert($('#new_email').val());
alert(window.top.$("#new_email_label.").val());
// alert(window.top.$("#<%= new_email_label.ClientID %>").val());
$(this).dialog("close");
},
"cancel": function() {
$(this).dialog("close");
}
}
}
);
});
</script>
And and modal asp.net is
<div id="no-email-popup">
<label>Enter Email: </label>
<input type="text" id="new_email" />
</div>
I want to get the value from Pop up back to to asp.net page and assign to label there
<asp:Label ID="new_email_label" runat="server">test top window label</asp:Label>
I found out that I cannot change the value of this label even
Please help how to get value to top asp.net page
Using .val() on a <label/> won't give you the inner html of said label. You would need to use .html() to retrieve it, or .html("something") to set it.
after (or instead) of your alerts, try: $("#new_email_label").val($("#new_email").val());
I have a issue with Jquery Modal dialog being called from a button inside an update panel..
here are the insights..
Javascript used for opening a Jquery modal dialog in aspx page..
<script type='text/javascript'>
function openModalDiv(divname) {
$('#' + divname).dialog({
autoOpen: false,
bgiframe: true,
closeOnEscape: true,
modal: true,
resizable: false,
height: 'auto',
buttons: { Ok: function () { closeModalDiv(divname) } },
open: function (event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); }
});
$('#' + divname).dialog('open');
('#' + divname).parent().appendTo($('form:FrmSearch'));
$('#' + divname).css('overflow', 'hidden')
}
function closeModalDiv(divname) {
$('#' + divname).dialog('close');
}
</script>
the button in aspx page..
<asp:UpdatePanel ID="upDialogs" runat="server">
<ContentTemplate>
<asp:Button ID="btnOpenDialog" runat="server" Text="Open Dialog" onclick="btnOpenDialog_Click" />
</ContentTemplate>
</asp:UpdatePanel>
The Div which needs to be called from code behind via javascript..
<div id="ErrorDiv2" title="Error" style="visibility:hidden">
<p><span class="ui-icon ui-icon-circle-check" style="float:left; margin:0 7px 50px 0;"></span>Please select an option among the results and try again!</p>
</div>
Finally the code behind ..
protected void btnOpenDialog_Click(object sender, EventArgs e)
{
if (ProfileID == null)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "ErrorDivOpen", "document.getElementById('ErrorDiv2').style.visibility = 'visible';", true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "ErrorDivShow", "openModalDiv('ErrorDiv2');", true);
}
}
Now the Issue in detail..
Without the update panel the modal dialog pops very fine but makes full post back..
I want to have only a partial post back and hence am using a update panel..
The following are the solutions I have tried..
Added update panel to the existing div, dint work.
added an update panel along with runat="Server" for the div, still dint work..
Can any one help me with possible solutions?
Thanks for your quick reply but I found another solution.
I added both update panel and runat parameters to the Div.
<asp:UpdatePanel ID="upErrorDiv" runat="server"><ContentTemplate>
<div runat="server" id="ErrorDiv2" title="Error" style="visibility:hidden">
<p><span class="ui-icon ui-icon-circle-check" style="float:left; margin:0 7px 50px 0;"></span>Please select an option among the results and try again!</p>
</div>
</ContentTemplate></asp:UpdatePanel>
Changed the code behind as.
if (ProfileID == null)
{
ScriptManager.RegisterStartupScript(ErrorDiv2,this.GetType(), "ErrorDivOpen", "document.getElementById('ErrorDiv2').style.visibility = 'visible';", true);
ScriptManager.RegisterStartupScript(ErrorDiv2,this.GetType(), "ErrorDivShow", "openModalDiv('ErrorDiv2');", true);
return;
}
Could you try injecting the javascript into a Literal control inside UpdatePanel, istead registering it with ClientScriptManager ?

I have two text boxes I need a functionality like If I am typing in 1st text box The text should be getting displayed in 2nd text Box with some other font. This is a web Application. And so Text Box doesn't have OnKeyDown event? Do you suggest any way to implement this?
Note: I don't want to implement this with Javascript.
Solution using an asp:UpdatePanel
With this approach, you don't need to write a single line of JavaScript by yourself; everything is handled by the control.
Page.aspx:
<asp:ScriptManager runat="server"></asp:ScriptManager>
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:TextBox runat="server" ID="text1" OnTextChanged="text1_TextChanged"></asp:TextBox>
<asp:TextBox runat="server" ID="text2" class="special"></asp:TextBox>
</ContentTemplate>
</asp:UpdatePanel>
Event handler for the TextChanged event, Page.aspx.cs:
protected void text1_TextChanged(object sender, EventArgs e) {
text2.Text = text1.Text;
}
Solution using ASP.NET and jQuery
Page.aspx:
<script type="text/javascript">
//As soon as the DOM is ready, execute the anonymous function
$(function () {
var textBox1 = $("#<%= text1.ClientID %>");
var textBox2 = $("#<%= text2.ClientID %>");
textBox1.keyup(function () {
textBox2.val(textBox1.val());
});
});
</script>
<asp:TextBox runat="server" ID="text1"></asp:TextBox>
<asp:TextBox runat="server" ID="text2" class="special"></asp:TextBox>
CSS for both approaches:
.special { font-family: YourFontFamilyOfChoice; }
Test Results
I've tested both solutions locally with Firefox 3.6, Opera 10.6, and Internet Explorer 8; both work like a charm.
Use jQuery (JavaScript) combined with CSS. This solution will not trigger a post-back: Your users will see stuff happen as they type.
CSS:
.normalFont { font-family: Arial; }
.alternateFont { font-family: Verdana; }
HTML:
<input ... class="normalFont" />
<input ... class="alternateFont" />
JavaScript (jQuery):
// When the DOM is ready, execute anonymous function
$(function ()
{
// store a reference for the input with the "alternateFont" class
var alternateFontInput = $("input.alternateFont")[0];
// execute anonymous function on key-up event on the input with
// the "normalFont" class
$("input.normalFont").keyup(function ()
{
// set the value of the input with the "alternateFont" class to
// the value of the input with the "normalFont" class (this)
alternateFontInput.value = this.value;
});
});
