IE8 Says It "cannot Display The Webpage" When Using A Dynamic PlaceHolder?

Aug 19, 2010

I have a ASP.NET page using a PlaceHolder. Grids are build programmatically and added to this PlaceHolder when the page is run. Example:

ASPX Code:

<asp:PlaceHolder ID="myPlaceHolder" runat="server" />


Code behind:foreach (var country in Tables.Countries())
{
var nGrid = BuildGrid(country.Code);[Code]....

This page works flawlessly in Opera and Firefox. Internet Explorer 8 shows me the "cannot display the webpage" screen.

Web Forms :: Find Dynamic Control In A Placeholder?

Dec 10, 2010

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?

Web Forms :: Finding Dynamic Controls I Add In A PlaceHolder

Jun 27, 2010

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:

And this is the button click event: [Code]....

Like I said, this code was working before but now it doesn't.

Web Forms :: Masterpage Dynamic Id In Placeholder Not Registering?

Jul 8, 2010

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.

Web Forms :: Dynamic TextBox Validation Not Working On DataGrid On PlaceHolder

Oct 22, 2010

I have a placeholder to which I programmatically add DataGrids... In the DataGrids, I programmatically add TextBoxes along with dynamic validations. Somehow, the DataGrids show up, but the dynamic validations don't work. If I set them to static, the blank space for them appears, but still, they wont work.

C# - Placeholder Containing Dynamic Table Is Empty Unless Create Table Twice?

Jun 4, 2010

I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet.

The obvious thing to do would be to call the file sitemap.aspx and have it return XML, but it has to be called sitemap.xml and look like an XML file (headers etc) to the requester.

Draw A Line Between Two Dynamic Points On A Webpage Using HTML?

Feb 10, 2011

I'm working within the confines of ASP.NET and HTML.

I have a gridview on the left and a gridview on the right.

When the user selects a checkbox in the left gridview and a checkbox in the right gridview, I would like a line to be rendered that connects the checkboxes.

Is there an efficient way to do this? Anything approaching this?

DrawLine(LeftCheckBox.Location, RightCheckbox.Location, Red, 1px)

The only thing I can think of that would be work, but be a poor solution, is positioning and stretching an Image vertically based upon where the selected checkboxes are.

MVC :: How To Put A Placeholder Before The "MainContent" Placeholder In The Generated View

Jun 3, 2010

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?

MVC :: Program Cannot Display The Webpage?

Nov 29, 2010

I'm attempting to deploy my new MVC 2 app to a windows server 2003 box (IIS6). The app is on it's own web site, scripts and executable rights given, asp.net version set at 4.0.30319. ASP.NET MVC was installed via the web platform installer and server was since rebooted.

I've used this technique in the global.asax to put ".aspx" in the URLs:

[Code]....

No matter what i do I still get an error on Browse: "This Program cannot display the webpage." Times out in Firefox. This is constant if i do wildcard or .mvc mapping, suggesting it is an IIS problem.

Nothing in the event viewer that displays any info or any error.

Is there anything extra special that needs to be done to get IIS to recognize MVC?
