Please Help. I have a EOGrid that is embedded in an EOTreeview. I want to click a cell/row on clientside/javascript in the grid and then update a callbackpanel.
How can I set the Trigger of the CallbackPanel to the javascript? Also, within the serverside how can stop the whole page from postingback. Using __doPostback appears to postback the whole page.
function OnItemSelected(grid)
{
var item = grid.getSelectedItem();
var membId = item.getCell(0).getValue();
var svrUrl = item.getCell(1).getValue();
var lname = item.getCell(2).getValue();
var fname = item.getCell(3).getValue();
var title = item.getCell(4).getValue();
var city = item.getCell(5).getValue();
var state = item.getCell(6).getValue();
var country = item.getCell(7).getValue();
var mstatus = item.getCell(8).getValue();
var nickname = item.getCell(9).getValue();
var val = 'MemberId=' + membId + '&SvrUrl=' + svrUrl + '&lname=' + lname + '&fname=' + fname + '&title=' + title + '&city=' + city
+ '&state=' + state + '&country=' + country + '&mstatus=' + mstatus + '&nickname=' + nickname;
document.body.style.cursor='wait';
__doPostBack("<%= button.ClientID %>",val);
document.body.style.cursor='auto';
}
<eo:CallbackPanel ID="CallbackPanel2" runat="server" Height="150px"
Width="200px" Triggers="{ControlID:GridItem;Parameter:}">
<iframe ID="embeddedFrame" runat="server" name="embeddedFrame" src="EditPage.aspx"
visible="false" frameborder="0" enableviewstate="true" scrolling="no"
style=" width: 883px; height:516px; left:4px; position: absolute; top: 4px;" >
</iframe>
</eo:CallbackPanel>
Thanks

Hi,
When you call doPostBack with the button, it is similar to clicking the button directly. In that case you should set the button as the trigger.
Thanks!

I put the button there as a test. However, it postsback the whole page. Is there anyway or better way of doing this?

Hi, Setting trigger to the button should definitely work. So I am not sure why it is not working for you. There are a number of other options as well: 1. You can set the Grid as a trigger, then call the Grid's raisesItemCommandEvent instead of __doPostBack. Here is a working example: http://demo.essentialobjects.com/Default.aspx?path=Grid\_i1\_i13raisesItemCommandEvent does pretty much the same thing as what you do in your code: calling __doPostBack. However it is directly associated with the Grid instead of a separate button. It also takes and carries an item index to the server side so it might be easier for you; 2. It appears that you want to update the src property of an iframe element through a CallbackPanel. If that's the case, you don't need a CallbackPanel at all. Just call getElementById to get the iframe object and set its src property directly with JavaScript and you should be all set; Hope this helps. Thanks!
