Oct 27, 2010I've watched the Slideshow videos and created a number of examples that run fine. The code I've attached at the bottom is the smallest one, but instead of hard coding the image locations, I would like to select the slides from either of the following statements, which return the top 5 images selected randomly from our floorplans database.
<asp:AccessDataSource id="AccessDataSource1" runat="server" DataFile="../fpdb/J3_2005.mdb" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER BY RND(INT(NOW*[SF_Total])-NOW*[SF_Total])" />
or,
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:J3_2005Slideshow %>" ProviderName="<%$ ConnectionStrings:J3_2005Slideshow.ProviderName %>" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER

Forms Data Controls :: Upload Image To Database - Couldn't Find File Path
Sep 8, 2010I'm trying to display images in a GridView (yes, still this...). [edit] Before I can come to that I have to upload some images to the database.

C# - Load And Display Image As Slideshow From The Server Directory?
Jan 27, 2010I use .NET C# , I dynamically create folder to store the image I upload, ex:
strFolder = Server.MapPath("./folder/folder_"+folid+"/")
So I could create different folders according to the page unique id. I have also created a thumbnail image from the image I have upload (cropped ones).
The problem I am trying to figure out is to display these images as a slide show from these dynamically created folder (display thumbnail in the page and clicking the thumbnail need to see the full size image just like slideshow).
I was trying to see examples in jQuery but its just client side. So is there any way to load these images and display as a slide show from the directory. Should I deal with DirectoryInfo in C#? Expecting a simple one.
