Web Forms :: Variable Width Image In User Control?
May 17, 2010I am new to web design so bear with me. I have an .aspx page with a user control at the top that is basically a container for an image. It serves as a banner spanning the entire page. The lower part of the page is a left and right sidebar with a main middle section.
The image is simply some text at the left layered over a background that fades from blue to white, top to bottom. Image size is 90 p. high by 1000 p. wide. How can I get this image to vary width withing the control along with the rest of the page when rendered under different screen resolutions?

How To Add An HttpHandler For Image Extensions That Depending Whether A Variable In The Web.config
Mar 27, 2010I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN.
An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup:
<img src='<%= GetImagePath()/image.png' />
I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work.

Forms Data Controls :: Nested GridView Control Returns "Object Variable Or With Block Variable Not Set" ?
Oct 20, 2010Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.
The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....
Object variable or With block variable not set.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object variable or With block variable not set.
Source Error:
Line 118: If e.Row.RowType = DataControlRowType.DataRow Then
Line 119: Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)
Line 120: If Not e.Row.DataItem("Status_ID") Is Nothing Then
Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
Line 122: End If
I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:
*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)
*If Not localLblItemReference Is Nothing Then
******************************************************************************************
To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.
In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:
Exception Details: System.NullReferenceException: Object variable or With block variable not set.

Web Forms :: How To Use Regex To Extract Links From Page
Jun 28, 2010I have downloaded the page and I'd like to place all links into the array of strings. I'm not sure how to make the regex work. I can't uncomment the thing either because it balks at the quotes. The idea is to place each link found on the page into list. How would I handle relative links if the link found is ../ or ./? For just ./ that could be changed to / but otherwise you have to map the thing to get a full url. Also each url put into the list has to be the local domain and not an external domain.
