How to select a row based on column value

Hi, I have a radgrid placed in my page which has data pre-populated with data.
Now in my javascript I have to select a row from radgrid based on the data in the variable.
So it has to get the specific row which has that value.
I need to know if I can select a row from javascript.

For e.g. My grid has data like following

1, 2, 3 (Header)
------------
1,2,3 (Data)
4,2,3 (Data)

Now i want to select a row that has value 4 for column 1 which is actually a second row. Also what happens when paging is enabled in such cases?

Add to uploaded files programatically

Hi,

Is there any way to add "fake" files to the uploaded files list ?

In the web app I'm developing, I have a "create / edit profile" page where the user can create/edit his/her profile ... ( once again, this page has two modes "create" and "edit" ) ... in the edit mode I want the RadAsyncUpload to show up the file that is associated with the user ... so I want to programatically add this file to the list of uploaded files :-) ..How can I do this ?

parameters lost when radopens page on another domain

Hi,
I´ve been trying to radopen an url as follows:
<telerik:RadCodeBlock ID="java" runat="server">
<script type="text/javascript">

function redebp(sender, args) {

radopen("http://www.redebp.com.br/LoginUno.aspx?p=169","redebp")
}

The page is correctly load but parameter p is always null.

If instead I open the same page on the same site as below,
<telerik:RadCodeBlock ID="java" runat="server">
<script type="text/javascript">

function redebp(sender, args) {

radopen("LoginUno.aspx?p=169 ,"redebp");

}
The page is correctly load as before, but now the parameter p holds the expected value (169).

Can someone please explain this weird behaviour ?

TIA
