Random r = new Random();

System.IO.DirectoryInfo d = new System.IO.DirectoryInfo(@"C:\YourImageDirectory");
System.IO.FileInfo[] fi = d.GetFiles();

int file = r.Next(fi.GetLength(0));
string FIleName = fi[file].FullName;

The easiest way would be to add a requiredFieldValidator control and set the properties.

Use the following code:

Dim bc As HttpBrowserCapabilities = Request.Browser
Dim js As Boolean = bc.JavaScript 'if js returns true then enabled else disabled
Dim cks As Boolean = bc.Cookies ' if cks returns true then cookies is enabled else disabled.

You could always put a large warning in your markup, then attempt to hide it with javascript. If javascript is enabled, then the warning is hidden. If it is disabled then the warning stays.

There is a topic at http://www.programmingknowledge.com/ImageUpload.aspx[^] discussed about inserting images into SQL Server and populating a datagrid with images. And those images are coming from the SQL Server database table.

You only use the javascript: protocol when you run code in an URL. An event is not an URL, so it doesn't use a protocol.

btnprint.Attributes("onclick") = "window.print();"

b { font-weight: normal; }

Datagrid Paging....

Hi!

Simply my prob is:

For Datagrid i used 3 events:

ItemCommand,Databound & PAgeindexchanged..
Here that Page index changed wnt work, Instead of that it redirects the page where i mentioned in the itemcommand event, this event takes the more preference than page index,
How can we solve..?

If u need more explanation:

I hv the datagrid name as dg. i want to do paginng in that dg control.

I am using c#.

I fetched the imagebutton control name as img to the dg.

If we clicks that img it has to go another form(Models.aspx).

For this i used:

dg_itemdatabound event for find the control (img)

dg_itemcommand event for redirects to next page(Models.aspx)

Now i used 3rd event for the same dg control:

dg_Pageindexchanged event for paging.

Problem is:

I got the Prev & Next Buttons in the dg but if i clicks that one it redirects the page to Models.aspx (which is i mentioned in the itemcommand event)

I am displaying the next form based on the click of the imagebutton dynamically..

instead of that it has to display the remaining values...

I hope u got my problem.., How can we solve this one?

Use the following code to detect whether cookies are enabled or disabled:-

Dim bc As HttpBrowserCapabilities = Request.Browser
Dim cookies As boolean = bc.Cookies

if cookies returns true then it is enabled, else disabled. Smile | :)
