Hello
Serialization is the process of transmitting an object either in binary or in some human readable format like XML. .NET supports automatic serialization by marking the class as serialize. For making the concept more clear assume that you have a webservice which contains some serializable classes and it's objects. When you are sending that object to the client machine, it will be transmitted as binary or XML format and another object will be created on the client machine. Hope you are clear now.

I am not getting connection with databases and serialization ? What do you want to do with this ?

I use ViewState for data that is valid only for this page and as long as the user stays on this page.
And Session is used to store data that has to life longer than the interaction with the page (for example for data that has to be present when the user navigates back to the page to restore some kind of state).
Finally I reroute the ViewState to the Session because I don't want to send it to the client side.

I have an object tag as below.
<object id="basket" name="basket" classid="http:/public/bin/RKSmartControls.dll#Reuters.Knowledge.SmartControls.DocumentDownload" height="0" width="0" VIEWASTEXT>
<param name="Protocol" value="<%= GetContextProtocol() %>" />
<param name="Domain" value="<%= GetContextDomain() %>" />
<param name="DocumentRetrievalURL" value="showDoc/Research.dox?docIDs=" />
<param name="AuthenticationToken" value="<%= Context.Request.Cookies[CookieNames.TICKET].Value %>" />
</object>
And from the javascript I am calling a method present in this dll as below
function SmartClientDownload(XmlString)
{
var err = "";
try {
alert("basket = " + document.all("basket"));
basket.Context= XmlString;
basket.Download();
}
catch(e){
err="There was an error on this page.\n";
err+="Error description: "+e.description+"\n";
alert(err);
}
}
Here I get an error Object doesn't support this property or method.
Sometimes it work sometimes it fails, Let me know if you have faced this issue.

You can use onItemDatabound event of the datagrid to write you code to handle the checkbox.

Hi,
I have a page with some textboxes ,buttons and FileUpload.
all is well. but when the user update the FileUpload manualy in it's textbox (Exp "c") there is no post back from any of the buttons on the page.
Only when the user enter a valid path like "c:" or uses "browse" the buttons are able to postback
How can I fix this or how can i prevent the user from entering text manualy to the FileUpload.

Just add this "contentEditable=false" to your input file tag. It will serve the purpose.

On the datagrid find the name of the textbox in tempplate control!!
then
txtObject.attributes.add("javascript function");
Remember that its a template control so only once you need to add the attribute!!!
Hope itll help!!!
