refresh an updatepannel through Javascript

hi all,
I have a gridview within an updatepannel and I need to refresh this updatepannel through javascript.

Following are the senarios:
1. A button is outside the updatepannel and it is trigged with updatepannel to bind the gridview but when i raise the button click event through javascript it is unable to refresh the updatepannel.
2. Though when i debug it reflect the changes in codebehind but it doesn't reflect until and unless I click in the button.

So is there any code to explicitly refresh the updatepannel through javascript?

Please help !!!!!

Thanks and Regards

Obvioulsy, because that's how AJAX works. Look at the source of your page and work out the JS to call to update your panel.

Your question shows that you have NO FREAKIN IDEA about anything that you're doing. How does .NET globalisation help you ? Are you even RUNNING .NET code on the client ? No, you're not.

So, I suggest you buy a book on ASP.NET, so you can learn enough to at least know when your question is stupid.

See CG's reply below - but also, out of interest, WHY? don't you want to do it as per the link? As CG says, you seem to know nothing about Web development at all, let aloone ASP .NET development.

Perhaps start with the ASP.Net tutorials, write a Hello world page and come back and ask questions then.

I have a client who asked me to make him a products catalog. but it needs to be dynamic.
he can enter any metadata he wants about the products and its gonna be searchble.
I'm still imaging the architecture, anyone have any ideas?

XmlHttpRequest..Open and Windows Authentication

Jamie Nordmeyer17-Mar-09 11:53

Jamie Nordmeyer

17-Mar-09 11:53

When a call to XmlHttpRequest.Open is made to initiate an AJAX callback, does the Windows Authentication ticket of the user ALWAYS get passed? I have a 3rd party application that I'm working on that makes an AJAX call every 5 minutes. On the server side, the code connects to a COM+ object (yes, unfortunately this is an ASP application) proxy, which in turn marshals the actual call to another server where the tied COM+ component lives. This works fine for varying lengths of time, but it never works forever.

Eventually, the application will record that NT AUTHORITY\ANONYMOUS LOGON will have made an attempt to create an instance of the COM+ component on the second server, when it SHOULD be the credentials of the logged on user. So somewhere, the user's credentials seem to be getting dropped. To me, it looks like it's an issue with the user's credentials being passed to the server during the AJAX call. Should this always be the case, and if not, when might the credentials not make it up to the server? Anonymous access is disabled on the site (Windows Authentication only), and the impersonation level on the COM+ component is Identify.

Thanks in advance. If I haven't provided enough details, let me know.

Userrights to show menus

hi, i don't know if this is the correct forum if not please transfer it to the correct one.
i have a question how to handle userrights.
at the moment i wanna make for my page userrights which menupoints the user can see. i don't use the asp.net membership provider. i have a user table , a role table a rolegroups table and a userright table.

when a user is logged in i look in the userrights table (from my masterpage where the menulinks are created) which menupoints the user can see (for example the user1 is in the group visitor1 he can see link1,link2, link3)

user2 is in the group visitor2 he can see link2 and link3

what are the best way to handle this ? because my solution is very slow. specially how can i use session variables or is there an effectiv solution

Re: Userrights to show menus

Why is it so slow ? Perhaps you need to reengineer it ? How are you generating menus ? I'd think if the menu never changes,. you could indeed generate it once, then store it somewhere. Or if it takes a long time to generate, you could generate it and store it so that you can just pull it from your DB, for example, without having to do the calculations every time.

Handler to write image from DB not working IE7

I have an .ashx file that loads an image (specified by id in querystring) and then writes it out to the client. This works perfectly in Firefox, but all I get is a red X in IE7 (I have no way to test IE6). Here is the method:

<br />
public void ProcessRequest(HttpContext context)<br />
{<br />
	int contribId = Convert.ToInt32(context.Request.QueryString["id"]);<br />
	byte[] buffer = Contributor.GetImage(contribId);<br />
<br />
	context.Response.ContentType = "image/jpeg";<br />
	context.Response.BinaryWrite(buffer);<br />
}<br />

Any idea what is wrong with this?

Re: Handler to write image from DB not working IE7

you could try

public void ProcessRequest(HttpContext context)
{
int contribId = Convert.ToInt32(context.Request.QueryString["id"]);
byte[] buffer = Contributor.GetImage(contribId);

context.Response.ClearContent();
context.Response.ClearHeaders();

context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(buffer);

context.Response.End;
}

I didn't get any requirements for the signature

Ok, so come to discover that there was some issue with the image itself and Firefox could display it, but IE could not.

Thanks for you suggestion though.

What is the problem with DNN ? which version of DNN are you using ? How did you start to build a web site using DNN ?
However, I think the main problem concern is your Data Base. Only the SQL Server data provider comes default with the installation of DNN. For MySQL you have to cutomize the code. you can check this like[^] for mysql provider.
But why are you going for Mysql ?
