I want to check whether gridview contain any row so that if grid view is empty i can print appropriate message.

Try setting the EmptyDataText property on the gridview. It is a message to display if the gridview is empty.

With the GridView control, you can use EmptyDataText or EmptyDataTemplate to display your message or whatever you want when the datasource is empty.

I have a Content Page with a Custom Content Place holder. How do I get my functions that do various calculations in the code behind page to show up in the Custom Content Area at runtime? Thanks.

Perhaps, I don't undertand what you mean with your Custom Content Place holder and Custom Content Area, but basically you can place a container in the content area and in code-behind you can call your functions to populate and assign the values to the container. More details could help.

Hi all,
Very much confuse with this.
I have a datagrid, and i am able to pass the value to javascript function through "onclick" event as below:
e.item.attributes.add("onclick","javascript:myfunction('"+value1+"');");
but, when i am trying to pass the value of the first row on datagrid through "onload" event as below:
dg.Items[0].Attributes.Add("onload","javascript:myfunction('"+value1+"');");
it's not passing the value.
I have to use onload event, so i can display default value th' javascript function.
Any help will be appreciated.
Thanks,
NIKI

Make sure that you run this code after the datasource is bound to the grid control. Also, you can keep using the ItemDataBound event handler, but you can detect the first row so that you only run your code with this row.

I am using a HttpHandler (the ASP.NET 1.1 DynamicImage control from MSDN --
http://msdn.microsoft.com/msdnmag/issues/04/04/CuttingEdge/
My project structure is like i have one project of Controls and one web application and one DAL in my project.
I have placed the DynamicImage.cs and CachedImageService.cs in the controls project.
It is mentioned in the site that a setting has to be made in web.config file also which is something like this:
"<httpHandlers>
<add verb="GET"
path="cachedimageservice.axd"
type="MsdnMag.CachedImageService,DynamicImage" />
</httpHandlers>"
But i am unable to add the same in web.config, it gives some rutime error.
The assemble name for both the files have been changed say deepak.controls
And for what is axd file used.
If anyone has any ideas I'd love to hear them.
Thanks!

thanks a ton. that link solved the problem.

In addition, you can also create a custom http handler in a file ending with .ashx which basically does not require you to configure in the web.config file.

Hello All,
I am wondering if anyone can point me in the right direction. I am trying to draw a line or possibly several lines within a div control using (x1,y1,x2,y2) points. I do not want to use VML or JavaScript, I am hoping for something native to ASP.NET.
Thanks in Advance

You can generate an image on the fly using GDI+ then save that image to the server for display using a normal IMG tag

I saw the GDI+ solution, however, the size of the div's vary and there is an image already in the div cotrol. So the only solution is to then create a transparent image with my lines on it that is dynamically generated and has a higher z-index?

Then you're pretty scuppered as I've been finding out!!!
There are no functions (AFAIK) that allow you to "draw" to an area of a webform - the only way to do it is to use divs - to draw a vertical line, use a div 1px wide, and 1px tall for a horizontal line...of course the problem arises when you wanna draw a sloped line hehe!
SVG an option?

hot apots are client side, nothing to do with ASP.NET - so the answer to your question is that you create them in exactly the same way you always have with HTML.

I have a webform application that is using Windows authentication. This may not be a tough question but I am new to ASP.NET. How can I give access to both Windows and Mac users without creating my own login page or specifying each user and password in the web.conf file?
Thanks,
Jeremy

Doesnt Windows Authentication just ask for a user name and password on an unauthenticated machine, through the browser? It shouldnt matter what platform the client machine is running. I could be wrong but doesnt the web server handle the authentication for web users... If you specify users and passwords in the web.config file I dont think you are using windows authentication anymore...
