This message means that you are trying to place a text box outside the page form. You need to ensure that you place the textbox between a form tag with runat="server". For example:
<br />
<form runat="server"><br />
<asp:TextBox id="textbox1" runat="server" /><br />
</form><br />
If you want the textbox to be in the table then ensure that the table is between the form tags.
The simplest solution is to add the form tag to the master page so that it wraps the content place holder, this means that any page that inherits the master page will automatically have the form tag. This is not best practice because it will mean that pages that do not use forms will have the form and therefore view state sent with them which increase page download times and eats your bandwidth, but for quick test solution its job done.
Hope this helps.

Hey guys
I have used OutPutCaching on a webpage. Now how I can measure what benifit I'm geting from Caching...!
|
|
|
|
|
You can use the Application_BeginRequest() and Application_EndRequest() methods in the global.asax file to determine the time it took to process the request. But here your question is How to measure the Performance of Output Cache. You may have to take a look at this MSDN article[^], It says that performance of the Output Cache has to be evaluated based on the hits to the cached entries because Caching utilizes the server memory. If the hits are low to the Cached entries then sometime it may affect the performance.

The second form is a normal plain vanilla HTML form. Hence it can not contain a serverside Textbox. You can opt for a simple Input Type textbox without a runat=server.

When I got the same problem, I used HTML controls and then complex javascript function....
The one thing (In my knowledge) which we can add with runat="server" is hidden variables..
|
|
|
|
|
ok one more thing i wanted to ask. delegates i know is a safe type function pointer. y should i use it , i am not getting it's utility , the same thing can happen if i directly call the funciton , then what's the need to incorpoate the delagates?

then why not file path , that would be very easy for you.

Retrieve the Image from the DataBase and set the Content Type of the Response Object and do a BinaryWrite of the ImageByte array using the Response Object. This Image display code should be on a seperate page. say if you want to display the Image in an image control then all you have to do is just set the ImageURL property of the control to the URL of this Image Display Page.
