C# - Trigger AJAX CollapsiblePanelExtender Animation From Code Behind?
Sep 13, 2010I am using an AJAX CollapsiblePanelExtender for several sections of a form. I can collapse a panel programatically using the following 2 lines:
ajaxCollapsiblePanelExtender1.Collapsed = true;
ajaxCollapsiblePanelExtender1.ClientState = "true";
However, the expand/collapse animation does not play as when the Expand/CollapseControlID is clicked. It simply appears in the collapsed state. Is it possible to trigger this animation programatically?
AJAX :: To Make Expanding/collapsing CollapsiblePanelExtender From Code Behind Smooth And Animated
Aug 24, 2010I've got a CollapsiblePanelExtender in place on a panel in test and it works like a champ. (I get excited about the simplest things). When I click the panel header it expands and collapses with smooth animation, as expected and desired.
But when I change its state via code behind, it seems I am merely changing its state and somehow bypassing the javascript that controls the smooth animation.
My markup is out of the box. I have added code behind and some javascript, but I am missing the connection. Here is the javascript:
function pageLoad(sender, args)
{
smoothAnimation();[code]....
And here is the code behind:
protected void btnExpand_Click(object sender, EventArgs e)
{
this.CollapsiblePanelExtender1.Collapsed = false;[code]....
Web Forms :: Want To Put Code In Dynamically Created Controls?
May 28, 2010I need to create web controls (e.g. label etc) dynamically.The problem is that for example,
on my onload event, I create a label. The text of the label is read from one line of a xml file.
But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:
Message (<#% MessageCount %>) instead of Message (4 ).
Web Forms :: Want To Dynamically Generate Asp Controls From Code Behind
Mar 29, 2010On my form I want to display n number of rows of asp textboxes where n is determined by the number of records in the corresponding database table. I can dynamically generate html controls and get the values via request.form but I can't figure out how to do the same with asp controls.
The output from the following code, displays the text boxes from the "input type=text" statement, but displays nothing for the "asp:textbox" statement. I would prefer to use asp (or third party controls) so would greatly appreciate help on how to render non-html controls dynamically from my code behind.

Forms Data Controls :: Dynamically Add CheckBoxes Using Code Behind
Dec 29, 2010I´m developing a database driven asp.net 4.0 application and are currently stuck with the following issue.
I need to dynamically add checkboxes using code behind. These checkboxes represent activities that the user may chose from by ticking the ones that they are interested in. I do not know the number or which activities that should be presented until runtime so hard coding checkboxes is not an option.
On the client side I need to keep track of which checkboxes/activities the user have chosen as I need to calculate the cost for these without doing a postback. I would like to use javascript to find out what activities that are chosen and also calculate the total cost using javascript.
To implement this I tried to use Page.ClientScript.RegisterExpandoAttribute (server side) and javascript (client side, but I do not manage as ticking any of the checkboxes will not fire a client side event. I´m also using Telerik RadPanelBar controler.
Below is my current not working implementation:
Code behind/aspx.cs
public override void DoLayout(Aranea.Common.EntityDOL.ProjectRegistration existingRegistration)
{
base.DoLayout(existingRegistration);
lblCaption.Text = "Payment page";
//Get collection
TrackableCollection<ProjectActivityBooking> acitivities = existingRegistration.ProjectParticipant.ProjectEntity.ProjectActivityBooking;
//Add datasource and bind
this.RadPanelBar1.ItemDataBound += new RadPanelBarEventHandler(itemDatabound);
this.RadPanelBar1.DataSource = acitivities;
this.RadPanelBar1.DataBind();
this.lblTotalBooked.Text = "Total Booked " + decimal.Round(totalBooked, 2).ToString();
}
void itemDatabound(Object sender, RadPanelBarEventArgs e)
{
decimal totalActivityPrice = 0;
//Get panelItem
RadPanelItem item = (RadPanelItem)e.Item;
//Create Checkbox
CheckBox chk = new CheckBox();
chk.ID = "box";
//create label
Label lbl = new Label();
//Get Activity
ProjectActivityBooking activity = item.DataItem as ProjectActivityBooking;
//trying to register my checkboxes
Page.ClientScript.RegisterExpandoAttribute(this.validator.ClientID, "ClientID", chk.ClientID);
//Get total activity price
totalActivityPrice = GetActivityPrice(activity);
//Get total booked
totalBooked += totalActivityPrice;
lbl.Text = totalActivityPrice.ToString();
//Set activity name
chk.Text = activity.ProjectActivity.ActivityName;
chk.TextAlign = TextAlign.Left;
//Add controls
item.Controls.Add(chk);
}
Client side code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PaymentPage.ascx.cs" Inherits="CX.Aranea.Client.WebFront.UserControls.RegistrationForm.Payment.PaymentPage" %>
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
<%@ Register Src="~/UserControls/CxStandardControls/CxLabel.ascx" TagPrefix="cx" TagName="Label" %>
<telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="400px" Height="30px"
Skin="Forest" ExpandMode="MultipleExpandedItems" ExpandAnimation-Type="InElastic" >
<Items>
<telerik:RadPanelItem Text="root" Expanded="false">
<ContentTemplate>
</ContentTemplate>
</telerik:RadPanelItem>
</Items>
</telerik:RadPanelBar>
<cx:Label ID="lblCaption" runat="server" />
<asp:PlaceHolder ID="plhChildren" runat="server"/>
<asp:Label ID="lblTotalBooked" runat="server"/>
//My custum validator
<asp:CustomValidator ID="validator" runat="server" ClientValidationFunction="validation"></asp:CustomValidator>
<script type="text/javascript" language="javascript">
function validation(source, arguments) {
var chkBox = document.getElementById(source.ClientID);
if (chkBox.checked == true) {
alert("This should work");
}
}
</script>
I´ve been stuck with this for some time now and have a nice deadline coming up :) I would be most thankfull if anyone could point me in the correct direction as I feel a bit clueless. Perhaps there is a much easier way of solving this? Perhaps my code is all wrong?

Forms Data Controls :: Trying To Build A Repeater Dynamically Through The Code Behind?
Feb 9, 2010I am trying to build a repeater dynamically through the code behind. I found this code on the microsoft site:
Protected Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Repeater1.HeaderTemplate = New MyTemplate(ListItemType.Header)
Repeater1.ItemTemplate = New MyTemplate(ListItemType.Item)
Repeater1.AlternatingItemTemplate = _
New MyTemplate(ListItemType.AlternatingItem)
Repeater1.FooterTemplate = New MyTemplate(ListItemType.Footer)
Repeater1.DataSource = New String() {"one", "two", "three", "four"}
[Code]....
So this code works without throwing any exceptions, but what I would like to do is accessing the DataSource inside of Sub InstantiateIn(). I know you can access the DataSource in the front end using DataBinder.Eval and Container.DataItem, but is there a way to access the data during the InstantiateIn() Sub?
Or if there is another way to do this i'm up for trying that as well. Essentially I am trying to avoid writing asp.net code, instead I would rather write everything in vb (code-behind)

The following code-behind is supposed to check those boxes that correspond to values stored in a database. It fails and I don't know why.

Web Forms :: Error In Production Environment When Dynamically Generating Script Code
May 6, 2010I am dynamically generating script code to return transaction data to Google Analytics using their ecommerce script. The code that generates the script is fully tested and functional on my development machine and when I view the page code the script, along with any values that were passed to it, can be seen above the </form> tag. Happy days, or so I thought. For some reason the code is not being generated when I test it in a live, hosted environment. I cant figure out why this is the case as the code is quite simple. I simply generate the script code and register it on the client side (see code below)
//Capture the transaction data for analytics ecommerce tracking
//Generate the necessary script code
string strAnalyticsEcommerceScript = Analytics_Ecommerce_Script_Creator();
//Register the script on the page
Page.ClientScript.RegisterStartupScript(this.GetType(), "AnalyticsScript", strAnalyticsEcommerceScript);
The page in question is called "Order-Successfull" and is where customers are sent to when they have succesfully payed for an order. On this page:
-The order is added to the orders database table
- The customer is emailed an order confirmation email
- The google analytics script is generated and registered
The Sequence is as follows:
[Code]....
Whats really interesting is that if I move the Analytics script creator code before the code that sends the emails, the script is generated and can be seen when I view the page code. If I do this, however, the emails do not get sent. If I lay the code out as per the code I have inserted in this post, the emails get sent but the script code is not placed on the page.. The code to that actually sends the emails is quite standard:

Forms Data Controls :: Adding Spaces In A String Which Is Generated Dynamically In C# Code?
Jul 20, 2010I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.
Forms Data Controls :: Gridview With Links / How To Dynamically Add Linkbutton Columns From Code Behind
Jan 26, 2010I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?
