At least, it should be something like that ~

<br />

}<br />

I think there are some wrongs in creating the user control. How did you create your usercontrol? What you should do is that just add the Web User Control in your project. Then, add the DataGrid to your user control. that's all you need.

I don't know why that was added, it was added when I added the code.

My bad, the code-behind is not totally empty. What I meant was that I haven't implemented any functionalty in the code-behind. I am using ASP.NET 2.0.

That's exactly how I have created the user control. The thing is that it's the datagrid that is causing problem. If I copy the datagrid to a control that is working that control will disappear in the intellisense.

Michael Sync wrote:

I register the control in the web.config instead of registering the control on every aspx page.

I wonder why you used ASP.NET DataGrid (which is old) in ASP.NET 2.0 while there is new control "GridView" available.

Sorry. I always use GridView in ASP.NET 2.0 project. So, you may also try to use it.

I might be an codeproject error. The CDATA tag is probably used when storing the code-block.

I didn't know that the DataGrid control was old. I will try the GridView instead and see if that works.

I was asking whether CDATA is automatically shown when you post your code in CP. (meaning CDATA doesn't actually exist in your code)

Datagrid is the control that we used to use in ASP.NET 1x project.

Once you got the focus then you can just hit the enterkey to fire the click event.

If you don't like that way then you can use the Javascript to get the hotkey and fire the click event from client-side.

Hi all,
Iam using a radwindow from telerik to popup a window inorder to update records in a gridview.
After update iam using window.close() to close the popup and go to the main page. SOMETIMES iam receiving this message when i save
"to display the web page again, Internet Explorer needs to resend the information you've previously submitted"
with a retry and cancel buttons. If i press retry the main page reloads normally. This message is not always popping up.
Any ideas why and how to avoid seeing this message.
thanks in advance.

Can you try with normal window popup? And let us know whether you got this error or not..

The way I understand about this error is that you got this when you try to refresh your page. So, maybe. your Rad control is refreshing its parent page when you close it.

Thanks and Regards,

I have tried it with normal window popup before but i have never faced this issue. However when i googled yesterday i found many developers facing the same issue with normal popup.
For rad popup, yes it is refreshing the main window and this is what i need, but upon refreshing that window the message appears. Through out my investigation for this issue, i read some articles saying that this is a normal act that the explorer do and this is a sort of security. They recommended using redirection (document.location.href) instaed of using window.close. This dont work in my case because i want to close the popup window and redirection keeps my popup open and redirect it and not close it and update the parent.
I know this is a bit crazy Smile | :)

but i need a solution if there exists.
thanks for ur reply Michael.

Unfortunately, this isn't very straightforward - js runs in the browser on the client, the C# code on the server. To call anything on the server you'd need to use AJAX to make a call back to the server.

I tend to do this with a callbacks page - straight apsx page, no markup, and a big ol switch statement in page load, which looks for a querystring param which indicates the method in the callbacks file I wanna call...

C# has already designed away most of the tedium of C++.

No, Ko Ye Htut.

The question that he was asking is about calling the server-side function from client-side. It's true that document.getElementbyID("IDName").Click() can invote the server-side click event. but your code won't work if he wants to call the normal server-side function (e.g. public void MyMethod(){ })

YeHtut wrote:
FireEvent

You can't just fire the event to invote the server-side method from client-side script.. but it is possible to do with Ajax.

Hi,
you can try this.

Make Javascript function like this.

function GetClientScript()<br />
{<br />
var str= "My test";<br />
var test = '<%= GetFunction()%>';<br />
alert(test);<br />
}

Here GetFunction() is C# function. This function must return something else this cant work.

Now call this function onClientClick of any asp.net linkbutton or button.

And here you are..

Thanks,
Sun Rays

This javascript is I was written in Aspx file.

Seem like you are confusing. The server-side script can be written in both class file (e.g. .cs or .vb) and aspx file. But if we want to write the server-side script in aspx file, you have to use <% %>.

So, the way that you showed is just writing the serverside code in aspx file. And it doesn't mean that you are calling the serverside function from client-side ( Javascript or vbscript or etc).

still confused? Okay. Let's say.. I want to call this function ( ServerSideFunction ) from Javascript when I click the button ( input button. not server-control). So, ServerSideFunction() should be invoked only when I click the button. (not on pageload).

How to do that? Smile | :)

I think so, anyway should be postback and call the Server Side function. Otherwise can not be called the server side function. AJAX is called partial postback and call the server function. So Main page is never refresh.

I know like this. If you know that ow to do with other way, please share it to me.

Thanks for best suggest. Smile | :)

Hello,

I have a ASP.NET page and this page has Listboxes and some other controls like label, text boxes and a Hyperlink. When I click the Hyperlink I show up a Panel as a message box.

The issue is as soon as the Panel pops up, The list box behind the Panel is still Visible. But rest of the elements do not. Is there something we can do to sendback this list box
