Hi everyone
Since the RadGrid doesn't automatically postback when a user selects multiple items from the RadGrid using the SHIFT key, you have to do it manually. I've implemented this behaviour by subscribing to the the RadGrid's client-side OnRowSelected event. All I do in the mentioned event handler is calling the RadAjaxManager's ajaxRequest method (also on the client) to trigger the postback:
| function RowSelected(sender, args) { |
| var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>"); |
| ajaxManager.ajaxRequest('StrgShiftCombinationPressed'); |
| } |
Should be that simple, but I have the following issue: Everytime I select multiple items with the SHIFT key, one item (actually, the last one) doesn't show up as selected after the postback. For example, if I select 4 items with the SHIFT key, first all the selected items are selected, but after the postback (and after the loading panel disappears), only 3 elements are selected.
To see what's going on on the server-side, I added an event handler for the RadGrid's server-side OnSelectedIndexChanged event. In the event handler, the grid.SelectedItems collection counts also one element less than selected (e.g. 4 items are selected with the SHIFT key, but grid.SelectedItems.Count evaluates to only 3). Also, if I select only one row with the SHIFT key pressed, the RadAjaxManager's server-side OnAjaxRequest is fired, but not the RadGrid's OnSelectedIndexChanged event (I have to mention, that I added the following AjaxSetting to the RadAjaxManager: radAjaxManager.AjaxManager.AjaxSettings.AddAjaxSetting(((MyMaster)this.Master).ajaxManager, radGrid) ). When I select 2 items with the SHIFT key pressed, the OnSelectedIndexChanged is fired!
This issue has been bothering me for quite a long time, and I would be very thankful if somebody could successfully point me where I'm doing something wrong.
Thanks in advance.
Greetings,

Hi,
I have a RADGRID with a DATABIND client-side.
The databind event is raised with a JS SETTIMEOUT function:
setTimeout('bindGrid()', 5000);
and in a bindGrid I have a regular call to my web service:
WS.GetDocumentsSelected(startIndex, pageSize, sortField, sortOrder, filtroT, filtroM, mozione, updateGrid, koMessage);
where filtroT, filtroM, mozione are a custom filter.
The return of WS is a below code
| function updateGrid(result) { |
| var tableView = $find("<%=RadGrid1.ClientID %>").get_masterTableView(); |
| tableView.set_dataSource(result); |
| tableView.dataBind(); |
| } |
It's work fine, but I have a problem with selected row:
If I selected the second row, e.g., and I execute a sort command, my row selected persist in the second row.
The same problem occours with paging-change and a filter changed.
I try to save my selected-row id in hidden-field and in data bound function set the selection manually with the follow code:
| function RadGrid1_RowDataBound(sender, args) { |
| var dkvs = document.getElementById("<%=DataKeyValueSelected.ClientID%>"); |
| if (dkvs && dkvs.value && (args.get_dataItem()["Id_doc"] == dkvs.value)) { |
| //args.get_dataItem().set_selected(true); |
| sender.get_masterTableView().get_dataItems()[parseInt(args.get_item()._itemIndexHierarchical)].set_selected(true); |
| } else { |
| //args.get_dataItem().set_selected(false); |
| sender.get_masterTableView().get_dataItems()[parseInt(args.get_item()._itemIndexHierarchical)].set_selected(false); |
| } |
| } |
after data bound the paging-change and a sort works fine, but if after row selected I remove my filter, I have all alternating item selected (after the selected row - see attached) .....

Hello,Telerik.
When I use Telerik gird,meet trouble below.
Scenerio is:
I have a List page which provides all kinds of querying condition by textbox or combobox(dropdownlist).
After I filter some data, I click one row I wanted that open a radWindow which provides function of editing selected row.
after I close the opened window, I return the list page.
How can I keep the textbox or combobox(dropdownlist) status that I just typed or selected , and only refresh the grid.
sometimes, I met "Retry/Cancel" popup when I use "window.location.reload(true)" .now I update "window.location.reload(true)" to
"window.location.href=window.location.href", Only do this, cannot keep the previous state of textbox or combobox(dropdownlist)
How to solve it?
Thanks
Best Regards

I have a panel bar that is built up of some pretty expensive database queries, I don't want this binding to happen per page load.
In my code I build up the panel using allocated RadPanelItems(), and than I was planning to allocate a RadPanelItemCollection() to put all the items into. Then I would only have to cache that Item Collection once across the site, and just assign it to the Items property of the RadPanel... But you can't do that.
The collection can only be constructed with a parent control, and once a control is built you can't assign a collection to it (get, no set).
How are you supposed to cache the items list in a RadPanel? I don't want it to have to cache per user, and I don't want to have the bind happen over and over.
Thanks.

Hi

Currently I have:
I have a databound Repeater control. I'm using RadWindow to show additional Data and pop up additional forms.
Currently I have:
GetRadWindow().BrowserWindow.location.href = GetRadWindow().BrowserWindow.location.href;
to reload the page so that any changes take effect. The problem is it relaods the whole page and resets any paramters that may be selected in a series of dropdowns. All I want to do is refresh the Repeater contol with Ajax from the RadWindow close.
How would I go about doing this.
