I wrote this code and it works perfectly to add controls.
When I click on the link button "Add group" it correctly adds new DropDownLists and LinkButtons, the problem is that the removeGroup function (which is added also dinamically) does not work.
Here is the code:
[Code]....
The panelGroup is within an UpdatePanel.
Suppose I have two controls in my page named Textbox1 (For the purpose of taking Employee ID as input) and another one is Button1.
I am using northwind data base and my server name is "DON".
The thing which i want is that when i click on the button1 the task showing below should be:
1. Disable the page (Like when we download the Ajax Tool kit from the Codeplex. An agreement come and the page gets disable)
2. A panel should be display as Image Shown Below
Is it Possible with the help of query string (if yes please make your answer query string oriented) a close button should be appear also in the top right corner of panel which should close the panel and re enable the form.
I have a weird problem, using ModalPopup extender. I am unable to add/remove the textboxes I need. I am adding a default textbox and enabling "Add" button to add more. The user should be able to remove the unnecessary textboxes.

How do i add and remove asp.net textbox dynamically with validation in gridview?
View 2 Repliesdo have a very particular question and if you want to answer it go straight to the end. But I do welcome comments and advices hence the lengthy post. we deal with a lot of forms and some of these forms are quite lengthy and have many fields. We also have a requirement - in addition to top level fields - to be able to have variable number of repating rows - as we call them. For example, let's think of a customer which has name, surname and age while it can have zero or many addresses (say 0 to 10) so the user must be able to add or remove contacts from the form while filling it in.
View 4 RepliesDoes anyone know how to dynamically add and remove rows in a table triggered by a button click from the backend (in c#) using asp.net?
Here's how it might be done in javascript, is there any way to do this in the asp.net framework?

I want to create a page that can create multiple aspx pages
Let me tell you the scenario
i have multiple clients and each slient has to send a report and number of clients can be any no. like 10, 20, 30 , 50 so its difficult for me to create a report page for every client. So My need is to create a page that can dynamically create a page suppose we say our mai page is like
Cliient Name TExtbox
textbox1 X
textbox2 X
textbox3 X
textbox4 X
textbox5 X
textbox6 X
submit button
now if we want 4 textboxes for client1 then user should click on X and two text boxes will omit for a particualrly that client and a page with 4 text boxes will create for client1
and similarly for client2 if for it we want 2 text boxes a page with 2 text boxes should be created
I have created a custom control with three dropdown list boxes. Based on the selectedItem in the first ddl, other two ddl items will be populated. I have this part working fine.
I have an asp:panel control, "Add", "Delete" and "Submit" buttons with in an ASPxRoundPanel on my web page.
btnAdd_Click event has the following code:
Control control = LoadControl(Path + "myCustomFilter.ascx");
control.ID = "FilterControl" + Convert.ToString(pnlCustomFilter.Controls.Count + 1);
((myCustomFilter)control).FilterDataSource = dtSource;
//Add to dynamic control panel
pnlFilterControl.Controls.Add(control);
First added control displays fine. When I add second control, I don't see pnlCustomFilter display on the page.
What code should go into Page_Load IsPostBack block to refresh pnlCustomFilter and myCustomFilter selected items? When delete button is clicked, I need to delete selected customControl from pnlCustomFilter. How do I get selected pnlCustomFilter.ControlId? How do I delete it?
I am working with a few .Net 4.0 webforms controls such as the Menu control and while I think it's great that I can now declare the way in which controls are rendered (i.e. as either tables or divs), I can't switch off the automagically-included javascript that manages the hover events for those controls, for example:new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false }This appears at the bottom of every page that owns such a control.

I there a way to dynamically add controls to a Modal popup?
What I want to do is put a modal popup container on the bottom of my pages .... then based upon the user action (say button click) I want to populate the modal popup with all the necessary controls for that action (ie. textbox, select list, user control,etc.). One button may be just a modal popup with a textbox and button, another might be a select list with button.
I have a GridView with a column of checkboxes. I also have a panel pnlSubmitOffer which serves as a modal dialog with ajaxToolkit:ModalPopupExtender:
[Code]....
I need a set of controls (text boxes and datetimepickers) to appear on the modal dialog based on how many checkboxes in the GridView are checked, i.e. a set for each checked record. Thus the controls should be added to the panel dynamically. But I don't know how to do it, as btnSubmitOffer click is not handled, because the modal dialog appears first. I was told that the controls can be added dynamically using javascript, but my knowledge of it is not enough.
I'm dynamically adding a calendar extender like so:

When a postback occurs I get the following error:
Extender control 'ceDateFrom' is not a registered extender control.
Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors().
Parameter name: extenderControl
I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?
I have an issue with gridview and ascx's inside. Into the item template I'm dynamically loading ascx files depending on the row hiddenfield value. Ascx control is then "opened" in panel with modalpopup extender. The issue is ascx control with ceratin programming logic behind does not postback in this scenario.
Is there any workaround here?
Here's html snippet
[Code]....
I am dynamically adding controls to a page with an updatepanel. The controls do trigger a post back but their events do not fire.
For example:
LinkButton link =
new
LinkButton();
link.Height = 45;
link.Width = 250;
link.Font.Underline =
link.Font.Bold =
link.ValidationGroup = "NoValidation";
link.Click += new
EventHandler(EventDoesNotFire);
I have set a break point on the Load_Page and in the EventDoesNotFire method. The Load_Page fires, but it never enters the EverDoesNotFire method.
is anybody interesting in share and join to develop callback web controls. My purposes is lower unsynchronized page development cost. I have developed a base class and a set of common controls. Currently, they allowed to be loaded dynamically in a control or ASCX via callback event using sample server side code. Control library code will automatically register javascript and render it on client browser. These controls worked fine in both callback and postback. To load dynamically from an ASCX file.
'ascx1.ascx contain some callback-able controls
Private Function LoadAscx_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As Control = LoadControl("~/Test2/ASCX/ascx1.ascx")
c.ID = "ascx1"
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function
Or to load dynamically as a control
'c is a callback-able TextBox
Private Function LoadControl_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String
Dim rt As String = ""
div1.Controls.Clear()
Dim c As New ACT360_CallbackControls.ZYH.TextBox
AddHandler c.KeyUp, AddressOf TextBox_KeyUp
AddHandler c.GetFocus, AddressOf TextBox_GetGocus
div1.Controls.Add(c)
If RenderMe Then rt = CallbackManager1.RenderControlHelper(c)
Return rt
End Function
So I have two UpdatePanels. I am dynamically creating server-side buttons in UpdatePanel2. When the buttons come out, they are not hooked to the asynchronoustriggers of updatePanel1.
So how can I dynamically add these triggers of these newly dynamically created buttons so that clicking these buttons will only cause a partial postback to UpdatePanel1 ? Right now, when I click these buttons, it causes a partial-postback refresh to UpdatePanel2 (the panel itself that which the controls reside in)
I have a small form with some static elements that I am able to access with javascript the bring up a popup. 4 textboxes are generated and attached to a updatepanel. I've been trying various methods of validating the contols without generating postback.
I found anytime i registered a javascript to the scriptmanager the page must refresh.
Is there anyway it can be done?
I have a tabcontainer which has 7 tab panels and on certain conditions i want to make 1 tab either visible false or remove from the TabContainer. Firstly, i had set tab visible false but by doing this my TabContainer1_ActiveTabChanged event fired twice intially when i select the tab panel then it fire and shows my correct ActiveTabIndex number but but at the same moment it fires again with 1 Decrement in ActiveTabIndex number.
I could not understand why it is happening.What thing makes the ActiveTabIndex number decremented by 1. If select Tab 3 then it shows me result of 2 and so on.
Why this event firing twice i set any tab Visible false.
Is it possible remove the last years of CalendarExtender ?
View 5 RepliesI have an Accordion displayed in a div...
The div's height is auto-sized by javascript to match the height of the window; the width is 100%
The body is overflow:hidden
The div is overflow:auto
The CssClass for the Accordion is just "accordion," and the only property in the css is "overflow:hidden;"
When the page renders, however, firebug shows the rendered HTML to be including the following div which appears to be a container for the entire accordion:
<div style="width: 97%; height: auto; overflow: auto;" class="accordion" id="ctl02_acc1">
</div>
Inside the above <div> I then have my first header:
<div class="accordionHeaderSelected" id="ctl02_paneSearch_header">
</div>
After that (also inside the first div) is some other div that I don't really understand...
<div style="height: auto; overflow: auto; display: block;"></div>
And inside of that div is my first Content div:
<div style="display: block; height: auto; overflow: auto;" class="accordionContent" id="ctl02_paneSearch_content"></div>
"accordionContent" also has overflow:hidden
I have tried setting AutoSize = false on the Accordion...
but what I end up with is a horizontal scrollbar from my div which contains the accordion, but then I end up with a vertical (and sometimes also horizontal) scrollbar for the div whose class above is set to "accordion"
What is adding all these overflow:auto tags? How do I get rid of them?
