GetSelectedItems only returns current page

We have a pretty simple grid, selected by a GridClientSelectColumn in each row. We noticed the other day that if we selected, paged, then paged back, we lost the selection.

Implemented the client-side persistence as shown here, works great!

However, the grid only lets us have access to the current page's selections through grid.MasterTableView.GetSelectedItems on the server side when updating. I also tried testing with grid.get_selectedItems() on the client, still only got the current page's selections.

Obviously, we want our users to be able to page through the options and then hit the submit button only once to save, instead of having to save on each page of the grid.

What am I missing to get the universe of selections from the grid instead of only the current page's selections?

Thank you,

Scott

Set sort arrows on the left

I have been asked to move the sort arrows to the left of the grid header columns. This means that they will be displayed before the text.

I was just wondering is this possible with a Telerik grid?

Adding hyperlink to Image?

Hi, I would like to check if it is possible to tag a hyperlink to a picture when using RadRotator?

Based on the demo, I don't see an example that is able to show case this functionaility.
From what I understand, Ratator just need a picture gallery source to work. It will load all the pictures inside the source automatically.

Would be grateful if anyone can answer my query, thanks!

args.set_enableAjax(false);

}

function RowContextMenu2(sender, eventArgs) {

var menu = $find("<%=RadMenu2.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

document.getElementById("radGridClickedRowIndex").value = index;

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

Hide\Show Panel in master page from content page with strongly typed controls.

I'm having an issue updating content on a master page, using strongly typed controls.

On my master page, i have public classes that expose the .visible property of an asp.net panel, the content page sets the param to true or false. I have a radajaxmanager on master page and proxy on sub page, however I am unable to ajaxify the panels on the master.

For the solution I would prefer not to use FindControl()

Can someone point me in the correct direction?
