I am writing a dynamic control that I want to pass in something along the lines of the following:
HyperLink myLink = new HyperLink();
myLink.NavigateUrl = "/Home.aspx?id=<%= DataBinder.Eval("PageId") %>";
myLink.Text = "The link";
myControl.Controls.Add(myLink);
I want to be able to resolve the myLink.NavigateUrl at run-time according to the context that myControl puts the control into in the end (this is not a WebControl and therefore adding to the collection of controls doesn't output to page).
vote-up@{puzzle.UserVote .... is not treating the @ symbol as a start of a code block @puzzle.UserVote == VoteType.Up looks at the first part @puzzle.UserVote as if it's supposed to render the value of the variable.
I'm building an asp.net app using themes, and I've assigned a theme to the app using the web config.
I have a bookmark icon that I want to use for my page and it is located in the themes directory, but I am having trouble referencing the themes location from a link tag in my header.
First I tried putting a code block inside the link tags href element, which did not work. Instead all it did was html encode the <% characters and output it directly to the browser:
I am able to put a code block inside an element in an hr tag though, so I don't know why it won't work in a link tag:
<hr test="<%=Page.Theme %>"/>
Then I tried doing a Response.Write inside the head tag, but I got an error saying the Controls collection cannot be modified because the control contains code blocks:
i saw few of solutions for this exception (like putting it in place holder, or replace the <% to <# ...etc) , but i don't get the idea about it, i mean what is the controls collection? and why it can't be modified if the added control contains code blocks?
I recently put some code <% %> code blocks in my Master Page. Note I've read of the "fix" for either moving things out of <head> or using <%# %> but neither of them work well for my application.
Now the weird thing is that I only get this error on one page of mine. All the other pages seem to work fine, so what actually causes this error? There is nothing I can think of that is unique about this page. It uses the script manager as does other working pages and there is just nothing extraordinary about this page. It does have quite a few custom controls on it, so hunting down what is different in this page is more difficult than usual.
So what actually causes the Controls collection cannot be modified because the control contains code blocks exception?
We are using Infragistics' WebDataGrid, but this question probably applies to all other grids. I am new to Infragistics (actually have worked with their controls years ago, but feeling new regardless!) and this application as well. So I'm looking to its existing code as a model.
I want to have a column called Tobacco with a Y or N value depending on if Smoker is true/false.
Ideally, the whole thing would be something like this:
I don't know if I need a Convert.ToBoolean in there somewhere but I tried and it didn't work and at this point I am just guessing which will take a long time for me to get it right.
I am getting http exception in of the method of class file (search.aspx.vb) like "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)",
I have tried placing Java script function in the body of Master page from header, whereas I just removed the Java script tag and its contents in search.aspx (as of its not required now). Still getting exception.
I also know that if we have something like this <%= in Java script function we need to replace with <%#. But I don’t have this kind of code in any function.
I want use meta tag in my page that read keyword from database
I set this code in my product.aspx page
protected void Page_Load(object sender, EventArgs e) { SqlCommand _cmd = new SqlCommand("select Keyword1 + ',' + Keyword2 + ',' +Keyword3 from House_info where BehCode=1115", _cn); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
[Code] ....
It worked correctly and show my keywords from database and show it in my product.aspx metatag
I have two other page

Now i want set meta tag in store.aspx page and i want fill store.aspx meta tag from my users table in data base
The code on one of my aspx pages is giving me this error:
I'm getting this on the code behind for export to excel on one of my pages.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).It is referring to this line Me.GridView1.Parent.Controls.Add(frm)
I have this code in the aspx page. I am using two gridviews. I need to have this on the page any way I can fix the code so I can use that export to excel you created?
and it was working well even After I upgraded my wevbsite to .net version 4 but when I started a new website from scratch in vs2010 using .net4 when I use ajax toolkit in this new site it is registered as folowing
and when I run the page I get the error The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>) I don't Know what is the reason for this. I noticed another thing. in my old website I was using thckbox script by using the files common.js, jquery-1.3.2.js,jquery.thickbox.js and puting them in a Javascript folder ad then registering them in Script manager as following
this was working well also but in my new site the jquery file version was jquery-1.4.1.js but also I added the old version f the javascripts files in the built in Scripts folder that is created by default b the new site and followed the same way in registering them in the script managerchange the JavaScript folder to the built in folder Scripts
but this doesn't work also in the new site I think that there is something diffirent in the 2 case which leads to this change in performance I wish your support and advice about how to solve this matter
I have a multiline (> 50 lines) textbox containing plain text. I want to add either a session variable to the text in this box. In asp I would have done it by putting in <% %> code blocks but in .net I am getting the following error: "Code blocks are not supported in this context". I assume therefore that this would need doing in code behind.
Is there a quicker way than putting all the text from the textbox in a string in code-behind and then adding the variable on like this? I would like to keep the text in my aspx page if possible.
I'm receiving this error on a page that previously worked fine, in fact the only change I've made to the page recently was to add another asp:TextBox and asp:RequiredFieldValidator control.
The page already had numerous ASP.NET controls on it, so I cannot see why these extra controls would make a difference, anyway I shall post the code below and hopefully you can see what the error is:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MeetingGenerator.ascx.cs" Inherits="usercontrols_MeetingGenerator" %>[code]......
I've an ASP.NET application running fine locally, I've published the site and copied all files up to the live server and all is not good.99% of the pages are doing just as they should be, but just two pages are complaining that they can't find the code behind file? This is kind of urgent (demo tomorrow), so any help appreciated. Error message below...
Parser Error Message: The file '/CompanyRoot/_ReactiveTaskManagement/ReactiveTaskPage/ReactiveTaskEdit.aspx.cs' does not exist.
I have a site map on my project and I have section which get values from sql database and it changes according to querystring Id value. In my sitemap the title of the page is everytime same. but I want tpo change it at runtime. I am using multiple sitemaps and My sitemap is not the default one. its name is rootSitemap. I tried some code which I got from msdn but it seems doesn't work for me;
[Code]....
Here is my sitemappath code which is situated in my master page;
Error: Microsoft JScript runtime error: Object expected
if (lstRecipient.Items[i].Text == ddlRecipient.SelectedItem.Text) { lstRecipient.Items.RemoveAt(i); isDuplicate = true; ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "AlertAdd", "jAlert('Recipient name is already in the list.', 'Duplicate Entry!');", true); }
Now in the same project for another requirement I have to introduce Antlr3.StringTemplate.dll. Which has a dependency on another version of the above assembly.
If I use the version of Antlr3.Runtime.dll which satisfies NHibernate , Antlr3.StringTemplate starts complaining and vice-versa.
I've been trying to get into TDD but am hitting some stumbling blocks. I suppose a simplified example would be the best way to explain. My first assumption is that I start from the top. I want a web page that displays a list of categories say. So I write a test for a CategoryController whose Index action should return this list:-
Code:
[code]....
Bingo our test will pass. Now my problem here is how does TDD drive us beyond this point? Our tests have passed and it fulfills out requirements but of course we know that a fully working app would need say an ICategoryService to be passed into the Controller and the controller would use this to retrieve the categories.
I have a facade class that my controller class calls out to and in that facade class, for whatever reason, I'm building a string a href element. And it resolves fine in casini but when it gets out in the real world like localhost it doesn't work. Is there a way to do this?
