I'm looking to create a custom date picker with code examples from several sources.Is the code to display/hide an ASP.NET control when a user clicks a button usually done with JavaScript or ASP.NET code? By display/hide, I mean within the page not a popup window.
View 2 RepliesI have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...
I have set up in javascript:
var onBeforeUnloadFired = false;
window.onbeforeunload = function (sender, args)
{
if(window.event){
if(!onBeforeUnloadFired) {
onBeforeUnloadFired = true;
window.event.returnValue = 'You will lose any unsaved changes!'; //IE
}
}
else {
return 'You will lose any unsaved changes!'; //FX
}
windows.setTimeout("ResetOnBeforeUnloadFired()", 1000);
}
function ResetOnBeforeUnloadFired() {
//Need this variable to prevent IE firing twice.
onBeforeUnloadFired = false;
}
I'm trying to achieve an edit screen where the user is warned before navigating away. It works fine except I get the pop up for normal post backs of button clicks. I'm hoping to avoid this so I'm figuring if I could determine which button was pressed it would work. Does anybody know how to determine which button was pressed in the indows.onbeforeunload? Alternatively anyone know a better approach to what I'm trying to achieve?
I have a time on user control, and button on the web page. On perticular time I want to fire button click event.
View 2 RepliesI am working on a feature to throw a warning message if the user has unsaved values in a form. I can see that in the next post there is a explanation about how to do that [URL]now the problem is that i need to do the same but using a ascx control and i don't know where put the next code in my ascx control.
<body onunload="checkSave()">
NB: I'm working on dnn so that i don't have any change to add this code in the parent page of the control.
There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript
One of my webpages has an asp.net ListView control, with an insertitem template defined. I would like to allow the users of the page to enter data in a text field in the insertitem template, press the enter key, and trigger the insert event (which normally happens when you click the 'insert' button). I've tried simulating the button click event in javascript, but that doesn't seem to be working.
View 2 RepliesI am having fileupload control having its "multiple" attribute equals to "multiple". I am facing a weird issue in CHROME browser. The isse is that onchange event of file upload control is not firing for more than 12 files selected at once. The event is firing if I have 10 files selected at once.

I need to display a large monthly calendar of events for one of my websites and was wondering if the DayRender event loops through all days in any given month when the calendar control is displayed on the webpage.
Here is some sample code i found on the MS website:

This part for the DayRender event is what i am refering to:
[code]....
The code above looks like it loops through the DataSet row by row and matches the e.Day.Date item. But i'm just not too sure about the loop going through all days in a given month displayed on the calendar?
i do not know what is going on my firefox!

I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?
View 2 RepliesThe coding is in ASP.NET 3.5.Here is the scenario.I am modifying a page that populates some data.In that page there is a table that displays pages. The pages have sub-pages and these sub-pages again have sub-pages.So thats three levels of hierarchal data presented.Right now its populated using asp:Treeview for easier display of the +(maximise) and -(minimise) images and all.Is that the best method?
What are the alternatives?
I am trying to attach a server-side event to lookup the city/state for the user-entered zipcode in a field like the one below.

Since there is no lost focus event to capture, has anyone had any luck getting this to work?

I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 Replieswell i have already created the rows and cells dynamically using asp.net table control ...but how to add an onclick event on that ...so that i could retrieve the corresponding cell when a particular row is clicked ...if it was a html control ,i could have used javascript but in this particular case m unable to find any solution..

I want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles:Can I call onclick event on client side otherwise on server side?the statement table.onclick=SelectRow(event) fires a bug!Code:
function Control_Init() {
if( !(document.getElementById) ) { return; }
for( var i = 0; i < Controls.length; i++ ) {
[code]...
I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
I've created two buttons using javascript; yes and no. I need to get the event triggered when the button is clicked.i.e... onclick=getvalue().
public void SetYesButton(string msg_button_class) {
this.msgbox_Yes_button = "<input type="button" value="Yes" class="" + msg_button_class + "" onClick="getvalue()";>";
}
public void SetNoButton(string msg_button_class) {
this.msgbox_No_button = "<input type="button" value="No" class="" + msg_button_class + "" onClick="document.getElementById('pagedimmer').style.visibility = 'hidden'; document.getElementById('msgbox').style.visibility = 'hidden';">";
}
