Web Forms :: Image Thumbnail Does Not Display

Mar 4, 2011

I have an Image control on my page that should display a thumbnail preview of the actual image. The URL property of this control is assigned through the code-behind using:

imgHolder.URL = @table.Row[0].ItemArray[0].ToString();

Before moving my files to another location, this assignment works fine (The files used to be located inside the application folder). But after moving all files to another drive in the same server, the images don't seem to render any longer. I can upload/download files fine but they just won't display as thumbnails on the page.

Forms Data Controls :: If No Image Then Display A Default Thumbnail?

Apr 9, 2010

I've got:

<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "PropertyDetails.aspx?propertyId=" & Eval("propertyId").tostring %>'><asp:Literal ID="Image1" runat="server" Text='<%# Eval("imageId", "<img src=""images/properties/{0}_thumb") %>' /><asp:Literal ID="Image2" runat="server" Text='<%# Eval("imageFormat", "{0}"" alt="""">") %>' /></asp:hyperlink>

which displays an image from my db.

However, if there is not an image - e.g. if my property record doesn't have any images associated with it, I would like to display a default thumbnail.

Forms Data Controls :: Displaying A Default Image In Gridview If Thumbnail Cannot Be Located

Nov 21, 2010

I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:

[Code]....

However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).

To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?

Image Byte Resize As Thumbnail

Aug 12, 2010

I have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.

I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested

Dynamically Image Resize From Web Directory And Display It - Not Thumbnail

Jun 23, 2010

i am facing a prblem about image resizing.. i know it is a common problem but the scinario is little different here. i have some image in my server image directory and also have their small 128 X 128 sized thumbnail..i show a page with those images like 'facebook photo album' and also linked another page to display them..when a picture is clicked it refferd to that page and that page loads the full sized original image along with picture comments bla bla..., the page width is fixed to 1024px, and the div's width is 800px max which contains the <asp:image..../>; that shows the full sized image. here the problem comes, when a original sized picture is greater that 800px then the remaining part of the picture is croped !! i know it will happen.. that is why i planned to show a thumbnail like pic which's size will be 800px max and link the page with a pop up java script page which will contain the full sized picture only. the problem is i can't resize the picture in a limit of 800px on fly.
