Remove Added Control With Javascript

Jul 17, 2010

I'm trying to removed the added controls. Here's the mark-up that adds upload controls to the page:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" [URL]
<html xmlns=[URL]">
<head>
<title>Multi File Upload</title>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data">
<p id="upload-area">
<input id="File1" type="file" runat="server" size="60" />
</p>
<input id="AddFile" type="button" value="Add file" onclick="addFileUploadBox()" />
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<p><asp:Button ID="btnSubmit" runat="server" Text="Upload Now" OnClick="btnSubmit_Click" /></p>
<span id="Span1" runat="server" />
<script type="text/javascript">
function addFileUploadBox()
{
if (!document.getElementById || !document.createElement)
return false;
var uploadArea = document.getElementById ("upload-area");
if (!uploadArea)
return;
var newLine = document.createElement ("br");
uploadArea.appendChild (newLine);
var newUploadBox = document.createElement ("input");
// Set up the new input for file uploads
newUploadBox.type = "file";
newUploadBox.size = "60";
// The new box needs a name and an ID
if (!addFileUploadBox.lastAssignedId)
addFileUploadBox.lastAssignedId = 100;
newUploadBox.setAttribute ("id", "dynamic" + addFileUploadBox.lastAssignedId);
newUploadBox.setAttribute ("name", "dynamic:" + addFileUploadBox.lastAssignedId);
uploadArea.appendChild (newUploadBox);
addFileUploadBox.lastAssignedId++;
}
</script>
</form>
</body>
</html>

Javascript - Is Possible To Remove A Behavior From An Element That Was Added Using $create

Nov 8, 2010

I am using the following code to create calendar controls on textboxes that have been dynamically created using cloneNode. The problem is that in IE it seems to add the behavior twice to the textbox causing it not to work. Is there a way that I can remove this behavior before it is added in ie only to prevent it from being added again? This works perfectly in firefox

var rawDateControlID = ctrlPrefix + 'txtStartDate' + tblPatientMedicationsRowCount;
var $tstCalendar = $("#" + rawDateControlID);
$create(AjaxControlToolkit.CalendarBehavior, { "id": $tstCalendar.attr("id") + "cld" }, null, null, $get($tstCalendar.attr("id")));

C# - Javascript Added Input Control On .net Postback?

Jun 23, 2010

What I'm trying to achieve/plan, is whereby a page loads with a set of inputs, e.g. TextBox, Radio List etc. Taking TextBox as an example, there is a button for the user to "Add" another textbox to the page (in the same group), e.g. Member1, Member2, Member3 etc etc.

Two questions:

I could add these with Javascript, however the resultant "save" on postback would not get these inputs? If so, how? The form needs to work without Javascript as well, so postback to dad another control is fine, however if I click the "add" button again, it will only ever add one control.

protected void btnAdd_OnClick(object sender, EventArgs e)
{
holder.Controls.Add(new TextBox { ID = "txtControl1" });
}

C# - How To Execute Javascript In A Dynamically-added User Control

Jan 30, 2010

I have a GridView of thumbnail photos within an UpdatePanel, with clickable icons in each row which each load a User Control containing a small Google Map into the relevant row. The idea is that the user can geotag (by clicking on the map) any photo in the GridView.

In the map User Control, there is some Javascript initialising the map:

function initializeMap() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById('Map'), {size: new
GSize(336, 200)});
// set the map controls, set the centre, etc.
}
}

Problem is: I don't know how to call the initializeMap() method. Because it's dynamically added to the page, any attempt to link it to the calling button by "onClientClick=initializeMap()" for example, gives a JS error, saying the method isn't defined.

I've tried

ClientScript.RegisterStartupScript(this.GetType(), "initializeMap", "<script type="text/javascript">alert('Here'); initializeMap();</script>");

but I don't think I'm on the right track with that one either.

C# - Remove Statically Added Controls At Runtime

Dec 9, 2010

The Scenario: I have an asp.net website where I show a div popup on page load for taking a few user details. When a user inputs the details, or closes the popup, I set up a flag cookie so that the popup is not displayed again for the user. The div is in the MasterPage so that it is displayed no matter on which page a user lands first time. The div contains an UpdatePanel which has all the controls required for taking the details. This whole functionality is working fine.

The Problem: Now this div popup is not showing(by setting display:none) on subsequent postbacks(which I want), but the html markup is still loading with the page unnecessarily adding to the page size. What I would idealy want to do is: Check if flag cookie is set. If no, show the popup, else remove the popup's markup from the page. Now since the div is not a server control, I cannot possibly remove it and the all the controls inside it. So, I thought of removing the UpdatePanel from the page:

protected void Page_Load(object sender, EventArgs e)
{
if (Request.Cookies["flag"] != null)
{
if (Page.Controls.Contains(updpnl_contact))
{
Page.Controls.Remove(updpnl_contact);
updpnl_contact.Dispose();
}
}
}

But I guess this tends to work with dynamically added controls only, and since the control is added at Design Time, it is not being removed. Is there any way I can achieve this?

Javascript - Add / Remove Items From One ListBox Control To Another ListBox Control?

Oct 10, 2010

I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.

[Code].....

I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.

Web Forms :: Dropdownlist Item Added Through Javascript?

Apr 19, 2010

I have a formview that when in insert/edit mode, has a dropdowlist and a linkbutton. The linkbutton opens a popup with another formview that allows the user to enter new items that are required to be added to the dropdownlist. When the popup closes, it adds any new items to the dropdownlist options (there may be more than one item added). The purpose is to prevent having to have my users partially add/update a record, go create a new item for the dropdownlist then have to come back and edit again since any new items won't be known until they are needed.

At first, I recieved the 'invalid postback or callback' warning and began reading up on the issue. Though there were several forum posts and web articles, most seemed a few years old so I thought I would find out if there were any subsequent changes that might help me out. I'm using vwd2005/ASP.Net 2.0 and do not have ajax (not available on my corporate web servers). In the page directives, I disabled EnableEventValidation but then I found that while other controls were updating, the value set in the dropdownlist was not and I had to make 2 edits anyway. Since new items in the ddl won't be around when it is rendered, i've read that I can't make use of registerforeventvalidation. ps. i have thought that i could save my viewstate, browse away from the page instead of use a popup, then restore the viewstate, but I'm concerned about being able to update the ddl while retaining the viewstate.

C# - Web Control Added In .master Control Type Not Found In Child Page?

Jun 7, 2010

I have a Web Site project, and within it I have a user Web Control defined in an ascx file.The control is added to the Site.Master, and it shows up correctly on the page and everything is fine.I need to override some of the control's fields on one of the pages that derive from Site.Master.

// In OnLoad:
MyControlName control = (MyControlName) Page.Master.GetBaseMasterPage().FindControl("controlID"));

The issue is that MyControlName doesn't register as a valid Type on the child page. If I add a second instance of the control to the child page directly, the above works as needed, but if the control isn't placed directly on the page, and instead is only defined in the master page, the type is undefined. The control is not in a namespace, and is defined within the project, so I don't know why it is having such an issue location the appropriate type.If I put a breakpoint in the OnLoad, the type listed for the control is ASP.my_control_name_ascx, but using that does not work either. Why can't the child class reference the correct type? Can I fix this?

Web Forms :: Provide Server Side Validation For The Dynamically Added HTML Controls Using Javascript?

Mar 5, 2010

I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
