I have a web form and i'm creating tables including radiobuttons dynamically according to a number entered from a textbox,this tables created in placeholders.I'm using update panels so when i click the radiobuttons the radiobutton dissappear and a textbox is created at the same place,if one cell is created there's no problem but at multi creation there's a problem,when i click one radiobutton,all of them disappear and textboxes created,btw there's a checkedchanged event created dynamically also.I try many ways but i can't find the selected radiobutton,what do i have to do?

My code was actually working before. I think since I switched to .NET 4, it may have stopped functioning.What I do is this: I add some TextBox controls inside a PlaceHolder control. Then when user clicks the submit button, I am reading values entered into these texboxes.
This is what's on the page:
[Code]....
This is how I add controls into my PlaceHolder:
[Code]....
And this is the button click event: [Code]....
Like I said, this code was working before but now it doesn't.

I am having problems finding my UserControls inside the Controls collection of a Placeholder control.
I have a ListView control with a PlaceHolder control in its ItemTemplate. OnItemdataBound for the ListView control I am adding a custom UserControl to the Controls collection of the Placeholder control. It all renders fine. My problem is when I try to find my user controls in the Placeholder. I just can't get it back. My code is below.
My objective here is to get to the input controls within my UserControl and call the save method of this.
PlaceHolder intakeBenefitHolder = null;
protected void lvIntakeBenefits_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
using (ListViewDataItem item = (ListViewDataItem)e.Item)

I have a nested table structure, a part of which is rendered by a ajax call that returns HTML from the server. The markup looks like this:
<tr>
<td><table cellpadding="0" cellspacing="0" border="0">
<%-- Content will be displayed from ajax call 1 --%>
<%-- Content will be displayed from ajax call 2 --%>
</table>
</td>
</tr>
</table>
.. more html
The ajax call returns the following html
<tr>
<td class="wpss_checkboxtd"><img width="16" height="16" src="../../images/someimg.png"></td>
</tr>
<tr>
<td class="wpss_checkboxtd"><img width="16" height="16" src="../../images/someimg.png"></td>
</tr>
In jquery, I need to insert this html for which i need an element to traverse to so that I can call the html() of that element. Unfortunately, if I use a div, for example:
<table cellpadding="0" cellspacing="0" border="0">
<div id="divAjax1">
<%-- Content will be displayed from ajax call 1 --%>
</div>
<div id="divAjax2">
<%-- Content will be displayed from ajax call 2 --%>
</div>
</table>
the classes are setup such that the div or a span causes other issues.

I am using ASP.NET MVC 2 in Visual Studio 2010. I have a ASP.NET MVC application with a master page that contains 3 content placeholders. When I create a new view from a controller by right-clicking the action method and selection "Add View", I end up with a ASPX page that does contain the 3 content placeholders but in the wrong order. This is by design because in the T4 template used to create views "TitleContent" will be used first followed by the "MainContent" and after that all the other content placeholders are put.
I have a subtitle content placeholder in my master page that I want to put before the "MainContent" placeholder. Is there a way to achieve this with modifying the Create.tt T4 template?

I have an .aspx form that has a place holder that allows a user to add controls on button click. Upon button click of "Remove last added control" the user will see the last control be removed. I have searched this and can capture the control that they are wanting to delete but am having trouble actually removing the darn thing!!
Here is my code that I have that iterates through the controls and finds the specific ID that i want to delete but does not seem to delete it due to my syntax I believe (Coded in C# in .Net envirnomnet).
foreach (Control c in myPlaceHolder.Controls)
{
if (c.ID == "myTextBox" + Convert.ToString(Session["Control_Count"]))
{
this.Controls.Remove((c));
}
}
The session["Control_Count"] is the highest or greatest value that is added to the page. (example of 2 control ID's: myTextBox1, myTextBox2.) I want to be able to Delete TextBox2 and leave TextBox1 and thought thi swas a way of doing so.

I am creating dynamic controls... i.e. ddl
DropDownList ddl = new DropDownList();
ddl.DataSource = data;
ddl.ID = id;
ddl.DataValueField = "Key";
ddl.DataTextField = "Value";
ddl.DataBind();
PlaceHolder1.Controls.Add(ddl);
Loading the controls to the placeholder.
Selecting a value and clicking the button, doing postback, I want to capture the value selected in the ddl. I was using "FindControl method" but it is not working, I guess because the controls are created dynamically and will not show due to stateless HTTP.
How else can I capture the values? Is there away?

Need accessing the rendered content of a PLACEHOLDER control. I dynamically add a web forms page to a placeholder using "TABLE" this works great (cell row table placeholder ) now I wish to take that placeholder and use the rendered page to generate a PDF document.
If it possible to access the rendered code how would this be done?

Can a placeholder control be created dynamically such that you can add controls to it later on?

My goal is to move as much code from the code behind page to the business logic layer. I'm having trouble with an event handler because the code can't see the method it will call (because the method is on the code behind page and the code in question is in a class in the BLL). CS0103: The name 'ButtonClick' does not exist in the current context (the error) b.Click += new EventHandler(ButtonClick); (the line)
Right now I'm considering to try it by adding the EventHandler from the code behind page after the PlaceHolder has been sent to the code behind page, but I'm wondering if I'm missing a better way. Is there a best practice for how to deal with this? Do I throw in the towel and just let the PlaceHolder be built on the code behind page (where it works fine)?

in my master page content place holder.
i have a grid which is going out of placeholder (as its bit bigger ), when page is loaded. i would prefer it to stay inside the placeholder or expand the placeholder.
Currently its going out side and when it moved out of placeholder it becomes transparent to the materpage default template.

I have a gridviewto which I have added a templatefield based column. In that template field there is a placeholder. I am adding either a textbox or a radiobuttonlist to that placeholder programmatically.
So the problem is that when the page compiles, the contents of the placeholder get tabulated. So each listitem of the radiobuttonlist is encapsulated by its own <td> and <tr>
Now I seriously would not want the items of my radiobuttonlist to get separated as I am using the jQuery UI to style them. Not that they are not getting styled, but not the way should be.
Following is my .aspx code that creates the CPL:

Following is my .cs code :

Following is the resultant compiled code. It is inside the <td> of the parent gridview:

I have a page onto which a flash video loads. The flash video was created in Adobe Captivate. Usually the 665x335 area where the flash video object loads just shows as an empty 665x335 frame (with a little picture icon in the upper lefthand corner) for a few seconds until the flash video finishes loading. Then the video appears and starts running. It makes the page look unprofessional. Does anyone have an idea how I could have a default image show in the 665x335 space until the video loads, then to have the video take over?

This works fine without using a masterpage. What is the masterpage messing up here. Basically creating all dynamic controls. Linkbutton>tablecell>tablerow>table>panel>placeholder. The linkbutton id is not being set when building. The link button id is registered fine when not using the masterpage. Also using ajax.

I have an ASPX page with two columns. The left column has a GridView control that contains a list of article titles as LinkButton controls. When a LinkButton control is clicked, the content of the article is displayed in the right column. Each of the columns
is wrapped in an UpdatePanel. So far everything is working .
Each article title has further descriptive text that is defined in the code-behind as labels within a Div object. Each Div is added to a PlaceHolder object on the master page. References to the Div objects are added as attributes to the LinkButton so that JavaScript is executed when the user rolls over the title and the Div object with the descriptive text is displayed.
The rollovers are working fine and displaying the correct text for the first GridView page. However, when I click a button in the GridView's paging row to advance to the next page of the GridView list, the rollovers are not updated. The text is what was defined for the first GridView page of titles. How should I get the PlaceHolder objects to update when the UpdatePanels are updated?
