AJAX Tab Control Rendered Hidden?
Feb 21, 2013
My Tab Container works fine on my development machine. But it doesn't show up my production machine. On closer inspection, the Production machine renders it as hidden. Any thoughts on why this would happen?
Mark up:
<asp:TabContainer ID="tcAuditMain" runat="server"
Visible="true" ActiveTabIndex="10" EnableViewState="true"
CssClass="NewsTab" Width="100%">
Rendered:
<div id="ctl00_ContentPlaceHolder1_tcAuditMain" class="NewsTab" style="width:100%;visibility:hidden;">

Here is (more) code that demonstrates the issue. If the control in the host page is removed the tab control renders correctly. Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link. Is this broken or am I doing something wrong?

I have downloaded the latest version of AJAX toolkit (AjaxControlToolkit.Binary.NET35) and add to asp web page as I did many times before without any particular problem. However this time I'm experiencing unwanted results that make me want to through the computer into my neighbor's pool. The tab control is rendered with the following inline style:
<div style="width: 500px; visibility: hidden;" id="TabContainer1">

At first, I should confess that I am not sure if it is a good practice or not. I have came out with the idea due to my practice of jQuery.ajax().
What I want to achieve is depended on this design:
//Server Side; an .asmx file contains a method like this:
[WebMethod]
public string NewContent(string parameter)
{
string renderedHTML = string.Empty();
switch(parameter)
{
case ("person"):
// create an asp.net panel with
// some controls in it that has form elements to enter person data
// render control and assign its html to renderedHTML
break;
case ("department"):
// create an asp.net panel with
// some controls in it that has form elements to enter department data
// render control and assign its html to renderedHTML
break;
}
}
And from the client I want to do this:
// Some html in the page
<script type="text/JavaScript">
jQuery.post('ajax/myWebServices.asmx/NewContent'
function(returnedPanelContent) {
$('.result').html(returnedPanelContent);
});
</script>
Question is:
How can I make it work? Briefly to have a webservice method that returns different asp.net Panel control content created programmatically so that I can get this control rendered as HTML in my client-side and insert it to my web page?

I downloaded and installed AJAX Control Toolkit, following this link
http://www.asp.net/ajaxlibrary/act.ashx.
The tab doesn't show on the Toolbox. I right clicked at the Toolbox and select Show All. The tab and the controls shows up but all controls are gray out, look like disable. How can I make enable?

I have the AsyncFileUpload control within a <asp:Panel> control that I toggle visibility True/False.
For Example when the page loads pnlEdit.visible = False. Then when a user clicks on a detail record in a grid I display the panel with the AsyncFileControl ie: pnlEdit.Visible = True.
Because the the AsyncFileUpload Control is not displayed on the page right away it errors when you try to upload a file. Would anyone know how I could preload the control or configure it.

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a tag with

I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

I want to call the corresponding html inside a Panel in code behind. How can I do that?
I have this
<asp:Panel ID="MyPanel" runat="server">
// other asp.net controls and html stuffs here.
</asp:Panel>
I want to get the HTML equivalent of MyPanel and all of its contents in my code behind say in PageLoad or some methods.

I have to add a dropdown control in the web part. I am rendering the part using HTML Strings as follows...
StringBuilder sb = new StringBuilder();
sb.Append(div id="content); There are quotes in the string
sb.Append(div class=""hb"">");
*sb.Append(div class=""someclass"">");*
sb.Append(h2 id=""contentpage_title"">Title");
**sb.Append(div class=""ctn_conferences"">");**
writer.Write(sb.ToString());*
I have to add a loaded dropdown control...so I declared..
protected DropDownList ddMyDropDown = new DropDownList();
Then added the control in the middle of the render where I wanted as follows...
ddMyDropDown.RenderControl(writer);
Everything is fine....except... the post back does not work. My event handlers are not getting executed.
When I add the control ...like Controls.Add(Control) then it adds at the bottom of the part. That is not what I want.
So how do I get the post back to work?

I've specnt a day experimenting on this and am none the wiser.
I am using ASP.NET 4 Menu control and I have tried styling it using both techniques (but not at the same time as this is not recommended) i.e. :
(1) ASP.NET e.g.
<StaticMenuStyle BorderStyle="Solid" BorderWidth="1px" />
And
(2) CssClass e.g.
. StaticMenuStyle
{
/*my css rules here ... */
}
When I view the rendered output source in a Internet Explorer I see the following code in the HEAD section:
[Code]....
Also, in the BODY of the HTML I see the following:
<a title="Menu Option" class="level1" href="/path/default.aspx">Menu Option</a> (When using ASP.NET for styling)
<a title="Menu Option" class="level1 staticMenuItemStyle" href="/path/default.aspx">Menu Option</a> (When using CssClass)
I would like clean and minimal HTML rendered output (using AP.NET Web Forms not MVC).
I assume the #Menu1 and class="level1" is automatically generated.
Questions
(A) Is it possible to have the #Menu style code placed in an External style sheet file by ASP.NET at runtime rather than in the HEAD section of the output web page? If so, how is this done?
(B) Where is the code for class="level1" and do we have any control over this?

There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.

I have a custom control that renders a button. I'm trying to attach a server click event but it isn't firing. My code is:
protected override void CreateChildControls()
{
btnRangeGo = new Button();
btnRangeGo.CssClass = "divSearchGo";
btnRangeGo.Text = Resources.CORE_Resource.S0C29; // Go
btnRangeGo.Click += new EventHandler(btnRangeGo_Click);
// Tried with no luck:
// this.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
// Page.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
}
private void btnRangeGo_Click(object sender, EventArgs e)
{
int i = 1;
}
OnRender:
btnRangeGo.RenderControl(writer);

I seem to have come upon an issue with XHTML 1.0 Strict compliance and ASP.NET AJAX. When a ScriptManager is included on the MasterPage, it renders the following tag:
<input type="hidden" name="ctl00$SCManager" id="ctl00_SCManager" />
In order to be XHTML Strict compliant, this tag must be included in a <div>, as is the VIEWSTATE. Even when Strict compliance is enabled in the web.config, the ScriptManager insists on rendering in a non-compliant way. This is currently blocking our transition to Strict mode, as it's the only non-validating tag on our pages.

I am using TreeView Control in Asp.net. I have placed this control inside a panel. The tree control is completely binded (we don't want populate on demand) with an Xmldatasource during a callback and then I call Panel.renderControl to return the response (HTML) to the client side callback handler. Problem: 1. The tree expand/collapse (on click of plus sign) is causing postback whereas when I normally bind a tree with xml during postback and without using renderControl of container control, the expand/collapse (on click of plus sign) is being handled at client side. I want to stop this postback and allow tree node to call javascript to toggle nodes as it does when tree is binded and renderd in case of normal page life cycle.(when render control function is not used)

I am having some problems with my DIV, it wont display over a a DIV that has a web user control in it. Below you can find my css. I believe I have done everything right and am hoping that someone can maybe see an error that I have made and help me out. If you need any other code let me know. I also wonder if its just IE rendering it wrong?

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.

I got a hidden control in a User Control, as follows:
Code:
<asp:HiddenField ID="workDateId" runat="server" Value="" />
The user control have a member:
Code:
public string WorkDateId { get; set; }
In the form load event for the user control I set the value of my hidden control to the value of my member:
Code:
workDateId.Value = WorkDateId;
I use the user control as follows:
Code:
var ctrl = (TestControl)LoadControl("TestControl.ascx");
ctrl.WorkDateId = "some nonsense";
var cell = new TableCell();
cell.Controls.Add(ctrl);
tblRow.Cells.Add(cell);
