C# - Accessing Code Behind Property In Server Tags?
Dec 10, 2010
Is it possible to access a code behind property for a server tag? I have a property on my code behind page that i want to pass into a javascript function i.e.
i want make html table in format so i used follwing code but it just print tags(rather than analyze them as html and give appropriate output )
[Code]....
Output got when tried to use TransList.ToString() output got was <html> <head> </head><body><table><tr><td>1</td><td>11/24/2010 12:00:00 AM</td><td>Paypal</td><td>30</td></tr><tr><td>2</td><td>11/24/2010 12:00:00 AM</td><td>Paypal</td><td>300</td></tr><tr><td>3</td><td>12/10/2010 12:00:00 AM</td><td>Paypal</td><td>240</td></tr></table></body></html>
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
I have a page where i am creating a number of <span> elements using clientside code.
I am creating the elements using jquery like this
[Code]....
But this returns a null object everytime. I have tried this code on a span that is on the page at the beginning and it works so i guess its something to do with how im creating the control dynamically.
I mainly do C# ASP.NET projects in VS2010. Once you've put masterpages and other things in place, I find the design view pretty much goes grey and elements can't be selected. This isn't so bad except that sometimes you need to access the little 'smart tags' at the top right of controls to do things.
In particular I'm trying to do this with some telerik controls, though the issue isn't confined to them.
Anyone have a handy tip to access this functionality (or miraculously make design view work!) ?
PS. I read in a few places that Shift-Alt-F10 may help. I tried putting my cursor in the control's tag and using it, no luck. Also I clicked the little rectangle below design view to select the control and tried it again- no luck.
why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :
'ASP.cart_aspx' does not contain a definition for 'RedirectToPayPal' and no extension method 'RedirectToPayPal' accepting a first argument of type 'ASP.cart_aspx' could be found
I programatically add meta tags to the head of each page using htmlhead, specifying the name and content. I now need to add new meta tags with property and content.
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
I'm trying to access the Data text Field value of a HyperLinkField inside of a GridView Control during the databind event. Normally, I could access any cell's value with some syntax along the lines the following in the RowDataBind function:
myVarText = e.Row.Cells(2).Text
But this doesn't work when trying to access the value of the hyperlinkfield. All that's returned is an empty string.
i have a usercontrol with a few dropdownlist....n i am using that usercontrol in few pages and depending on pages those dropdownlist can be enabled mode or disabled mode.
so i created a property:
[Code]....
Now i am accessing in HTML as
[Code]....
it seems to work.
Just curious know that am i going in right direction or any better approach is available?
I need to access a custom property of web part(that wraps an ASP.NET user control) from JavaScript. Is it possible ? I need that property value so that I could pass that to an AJAX web service then.
So here is the problem , Is it possible to get the "SelectedItem.Text" of a binded dropdownlist? because everytime I'm getting null Even though I'm having items in the dropdownlist.
I'm getting the items that I want in the dropdownlist but I can't find out which one is selected.
There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?
I understand how to localize controls like buttons etc. I'm wondering how to accomplish the same thing with META tags.We use the following code to set META tags from code behind:
Title = AppConfig.CompanyName + " | [some prose that is specific to the page"; // Build META tags
I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like [Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
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:
Inside my Asp.Net MVC application, in the comments section the user will be able to add html tags (p, h1....) but the problem is: how can I remove any malicious code (script...) from the code the user has submitted?
My requirement is to catch the event of an HTML tag being generated because of an asp.net server side control. I want to add an attribute in the HTML tag. For e.g. the following asp.net code
I am generating xhtml in code that is then inserted into the page. Are there class(es) that help with adding tags etc. Then having a function that will output it to a string. (like the xml dom api) code like:
