Web Forms :: Accessing Image Control Properties?
Apr 6, 2010
I am writing my own captcha generator page using an aspx form that generates an image.
In the form that displays the captcha I have the following img tag -
<asp:Image ID="Image1" runat="server" ImageUrl="~/captcha.aspx" />
and things works well.
What I want to do is use the image tag with width and height specified properties -
<asp:Image ID="Image1" runat="server" width="100" height="50" ImageUrl="~/captcha.aspx" />
and in my captcha.aspx read the width and height properties in my captcha generator vb script.
How can I access the width and height from my captcha generator vb script?

I am currently working on a page that displays a set of questions as retrieved from an XML source. I can print the questions out fine by using a ListView and the ItemDataBound event. On PostBack it seems I can get some property values (Text), but not others (ID). I need to get the ID so I can match up the answer to the appropriate question.
Here is the ListView:

I just don't understand the Life Cycle stuff that well for advanced issues like this. I'd prefer not to use the Request.Form collection for this, but I will if it's the last resort.

I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
However, using the following syntax:
<td style="display:<%#(Container.PageControlMode == PageControlMode. PageMode.Wizard) ? "none" : "inline" %;">
I have the following property in my code behind:
public PageMode PageControlMode { get; set; }
Does not work and generate errors.

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 am using a backgroundimage in a <div>. The image itself has the dimensions 1246 * 1488.
I have set the div property to the same size in the .css file: 1246 * 1488
In the image I have some written text. But now when I open this up in the browser, the image is a bit wider wich makes this text "Blurry"
I wonder why this image is getting bigger in the browser:

I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.

We have added some custom profile properties to the web.config - what we want to do is have the code access them once (when user logs in) and cache this so that the code doesn't have to hit the database each time we call Profile.<our custom profile property name>
What we see is a call to GetProperties or GetProfile each time we access Profile. <our custom profile property name> - whats the recommended way to do this?

I have implemented a CollapsiblePanelExtender with a button that collapses/expands a panel. I also have a javascript function that can collapse the expanded panel when a certain condition exists somewhere else on the page.
The problem I am having is when I programatically collapse the panel, the extender is not aware, so the Collapsed property remains false and the CollapsedImage and CollapsedText are not updated. The next time I click the button, the extender is updated to a collapsed state, but nothing happens on the page because the panel was already collapsed. It is just resynchronizing the Collapsed, CollapsedImage, and CollapsedText properties to match the panel's already collapsed state.
Is there a way I can update the Collapsed, CollapsedImage, and CollapsedText properties in javascript to match the actual state of the panel?

I'm embarrassed to ask this here because it's clearly been duplicated several times already on StackOverflow. I've read a lot of stuff including:

I think I've done exactly what those article say, but it's not working for me.
Here's the top of my master page, named "MasterNoNews.master":

In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.

I want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

I have a LoginView control that contains a PasswordRecovery control. Upon page_load I don't want this to be visible. When the user clicks a hyperlink button ("forgot password?" type of button), then it'll be made visible.
But I'm having a hard time making the password recovery control invisible at runtime. Here is my page_load function:
[Code]....
It is the only password recovery control in the LoginView control, so I don't understand why this isn't working. The password recovery control is still visible when the page loads in my browser.
