Ok if you say so, I'll resist my urge to explain something next time. By the way, I am catching up on you in unnecessary responses... now we both have two in this thread :P

How to set CSS class to tbody of GridView? When I set the css class in Row-Style property, all rows have been set with this style which is I don't want. I found the way to set CSS class in thead and tfooter of GridView. but not for tbody. Is it possible to do with CSS adapter or normal way?

For example

If I wrote the code like that,

HTML View

<asp:GridView ID="GridView1" runat="server" >           <br />
</asp:GridView><br />

Code-behinded File

protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        List<string> list = new List<string>();<br />
        list.Add("Alien");<br />
<br />
        GridView1.DataSource = list;<br />
        GridView1.DataBind();  <br />
<br />
    }<br />

the HTML tag will be generated as fellows by default ~

 <table cellspacing="0" rules="all" border="1" id="GridView1" style="border-collapse:collapse;"><br />
            <tr><br />
                <td>Alien</td><br />
            </tr><br />
</table><br />

I noticed that there is no thead or tbody or tfoot in the generated HTML table. I want GridView to generate the HTML table with those tags. So, I tried with the follwing code.

        <br />
         grid.UseAccessibleHeader = true;<br />
<br />
        grid.HeaderRow.TableSection = TableRowSection.TableHeader;<br />
        grid.HeaderRow.CssClass = "fixedHeader";<br />
           <br />
        grid.FooterRow.TableSection = TableRowSection.TableFooter;<br />
<br />

then, I can add thead, tbody and tfoot to generated HTML successfully. It allows me to set the custom CSS class by using HeaderRow.CssClass and FooterRow.CssClass properties. But I found no way to specify the custom CSS class for tbody. So, it would be great if anyone tell me to achieve this goal.

Thanks in advance.

As in, FormView stayed in edit mode? Or database wasn't updated? Was updating event fired for FormView? And for SqlDataSource?

Not even postback? Do you have any validators there?

That's the better alternative I think Smile | :)

Check if you see any javascript errors on the page, browser plugins like firebug (for Firefox) will let you debug the javascript.

I mean, aren't there any ASP.NET validators that prevent page from postback?

Yes, they all do, if run on the client side.

Hey all.
Im struggling to understand and get this to work.
Can anyone tell me step by step how to use an RSS feed to display news headlines in my Website. I have no clue how this works....? Do i create the RSS feed? Do I download it? How do i use it?
Please help

There are lots of articles and tutorials out there on how to consume RSS feeds - even some here on CP. Search the articles and Google for "RSS consume web page"... no-one's going to write a whole tutorial just for you here...

Do some basic research, then, if you have a specific question...

The reason why i worded my query the way i did is because I have already done 6 tutorials off the web and none of them worked. So i posted a comment in order to hopefully find someone who has used them before.I dont want anyone to write a tutorial for me... But thanks anyway for your brilliant suggestion.

PageIndexChanged not firing in DataGrid if EnableViewState is false

19-Aug-07 22:29

Well, honestly, I have never done this (consuming RSS feeds) before, but it took me all of 10 minutes to follow this example

http://aspnet.4guysfromrolla.com/articles/031903-1.aspx

and get it working. All I would say is, that you have to a) find out the URL of the RSS feed you want to xonsume - and most websites that have one will display it, or else search for it on Google; and b) you will probably have to examine the XML returned to ge the appropriate field names. You should also probably server.htmlencode the description field at least.

Here is my code for my working example: (Click thr button)
I'm afraid I'm out for thr day now, so you're on your own after this....

recentPosts.DataBind()
End Sub

Function GetRSSFeed(strURL as String) as DataTable
'Get the XML data
Dim reader as XmlTextReader = New XmlTextReader(strURL)

'return a new DataSet
Dim ds as DataSet = New DataSet()
ds.ReadXml(reader)
Return ds.Tables("item")

Hi,

I want EnableViewState = false in order to optimize the end output page but when i turn it off, my pageing functionality no longer works mainly the PageIndexChanged event no longer fires, how do you handle this with enable view state as false?
I have tried every thing possible to make it work but it is not working. I refered few forums in which people were facing similar problems but no one was able to provide some concrete solution for the same. Please refer the below links where people have faced similar problems but the solution provided is not reliable:

http://www.west-wind.com/WebLog/posts/211.aspx
http://www.velocityreviews.com/forums/t67338-pageindexchanged-not-firing-in-datagrid.html

I've tried explicit event hookup but still it did'nt work.

I know if we call the data generation method before the page change method it will work but in this case the data generation mehtod will be called twice first before the page change method and second in the page change method, this will result in huge performance degradation and i want to avoid it.

Let me know if it is a genuine bug in ASP .NET or there is some way out to this problem. An early reply will be really helpfull.

thanks!

Well of course it won't work if EnableViewState = False - how can it?

if you want to minimise the size of viewstate on a page where it is needed, then you must disable it (set to false) at the individual control level, not page level (obviously only for those controls that don't need to post back their state...)

Thanks for your reply, but it is practically not possible for me to keep enableviewstate true since there are huge reports. Hence for my case i have to keep it false. Is there any other way out and is it a bug in ASP.NET

Thanks!

Re: PageIndexChanged not firing in DataGrid if EnableViewState is false

18-Aug-07 4:08

No, it'a not a bug - it's by reading the viewstate that asp.net can perform the paging; if you turn it off, it has no way of knowing what page you are on.

If you really want to turn it off (though if you are displaying that much "huge" information on the page I'd suggest you look again at this: perhaps links to the individual reports would be better?) you will have to "fake" your own paging instead of relying on the datagrid's inbuilt functionality.

Only read and display the first 10 (?) records; find out how many there actually are and dynamically write links to each set of 10... each link will cause the page to reload pulling only the required records (bit more coding there for you to work out!), and you will also have to re-calculate and re-write your page links again each time....
