I'm using lightbox [URL] .... to display a 6 images in a ASP.NET repeater looks great and almost does every thing i need.
I have set the .vb to make imagename.visible=false if the imageUrl=""... again works like a charm and I only see images that have a value in the database.
The problem i have is in order to list how many images in each set Lightbox uses an attribute in the HTML Hyperlink tag called 'data-lightbox'.
Code:
' href="<%# "../uploads/" & DataBinder.Eval(Container.DataItem, "image5") %>">
' width="45px" runat="server"/>
The problem is that when 3/6 images are uploaded and populated in the database lightbox still says there are 6 in the set even though only 3 are visible.
What i would like to do is in the .vb code when i check to see if the database field for the image is blank is set the data-lightbox value accordingly so visible images get a data-lightbox value only and are therefore added to the set.
Tried a .net Hyperlink too but same issue...
Code:
' href='<%# "../uploads/" & DataBinder.Eval(Container.DataItem, "image") %>'>
' Visible='<%# IIf(Eval("Image") Is DbNull.Value, "False","True") %>' width="280px" runat="server"/>
How can i change a custom attribute in a HTML form from the VB.net code behind?
I need to show an image and then 4 pointer small images. The user then has the facility to grab each of the pointer images and drop them on the large image.
Is this possible and if so how do I go about getting started or is there and third party controls out there that will do the job.
I need to write a routine which uploads a largish (2-4 meg) jpg photo and shrink it down to a small size. Adobe image ready does what I need but I need to develop it in my web application. Basically I need to reduce the image file size so it is web friendly.
