Refresh RadGrid client object on postback
Hello,
I initiate a postback with __doPostback function and pass some data which should help to set a VERY custom filter on dataset. But when page is reloaded, I can see that grid client object was not refreshed and all data and AJAX cell controls was the same as before. Grid is in ASP.NET panel which is under RadAjaxManager control. Is there a way to fully reload grid client object on postback?
Thank you.

UPD. Almost forgot - grid is created programmatically in Page_Init method.

Close RadWindow with Button
image Captura: the scenario
I have a Grid, and a button named Full Edit. When click in Full edit, open a Radwindow.
In Radwindow I have 3 buttons, Ones is Delete.

When User Click in delete, appear a RadWindow.Confirm (Deelete this User?)
If user click on Yes, remove user, close de windows and rebin the Grid.
this problem is RadAjaxManager1_AjaxRequest does not exececute Close and Rebien of JS

In save button, the user apply change, save and close (with intermidate windows) )this button wiorks.


This is my code:

Download Document Inside Ajax Panel
I've been trying to figure out for quite some time now how to download a document from a gridtableview that is inside of a RadAjaxPanel.  The only way I can get it to work is if I remove the RadAjaxPanel.  Also note that the download fuctionality resided within a detail table of the master grid.  Any help would be appreciated.

Thanks

Add new Button to RibbonBar in RibbonBar's ButtonClick event handler
Hi,

I want to add new commands to the RibbonBar inside the RibbonBar's ButtonClick event handler. Unfortunately, this doesn't seem to work as they are server-side added, but aren't visible on the client.

How I can I achieve this?

Thanks!

Edit: The ribbon bar is used in an AjaxManager:
AjaxSetting ajaxSetting1 = new AjaxSetting(m_ribbonBar.ID);
ajaxSetting1.UpdatedControls.Add(new AjaxUpdatedControl(m_contentPanel.ID, loadingPanel.ID) { UpdatePanelHeight = new Unit("100%") });
RadAjaxManager1.AjaxSettings.Add(ajaxSetting1);

In the ButtonClick event (in the same case where it is necessary that the ribbon bar changes), the m_contentPanel (it is just a div) is cleared and another control is added to the content panel.
When I try to add commands to the RibbonBar, the LoadingPanel also never disappears in the m_contentPanel. If I just add the new control without changed the RibbonBar, the LoadingPanel disappears and the control is displayed correctly.

RadUpload stop working when activating additional site language
Hi!
We are currently using the Upload control on some custom modules (old RadUpload v. 2.4.7.0) with no problems. The DotNetNuke installation version is 05.06.02 with Italian as default site language; the english (US) language is also installed and currently disabled. We encountered the following very strange issue: if we enable the english language RadUpload stop working; only very small files (tried with sizes smaller that 1kb) are uploaded but larger files not anymore. No errors visualized or recorded anywhere cause the code do something only if UploadedFileCount is greater than 0 but it returns 0 (it returns the correct file count only with very small files).
Any idea?
Thank you.

Setting edit column to open javascript lightbox
Our grid is currently set to use inline editing. As such, it has an EditCommandColumn with an image button that, when clicked, turns the BoundColumns into text boxes for editing and the EditCommandColumn into two image buttons to update or cancel. This is pretty standard. What we'd like to do is this: When the edit image is clicked, our javascript lightbox (specifically jQuery Colorbox) pops up containing the text boxes for the columns that can be edited, along with the update and cancel buttons.

I'm not sure of the best way to structure the grid in order to do this. I've been searching around for a while and have just been going in circles. Any help would be much appreciated.

tree view as navigation and UI for making server changes
I've spent days trying to solve what shoud be a very simple thing - getting a bit frustrated now as could acheive this with "regualr" ajax and asp.net, but totally lost with Telerik! Hopefully just ignorance on my part...

I have  tree view control which will be the navigation. It sits in a rad splitter on the left side. On the right side is the area that will be affected by clicks on my tree view. For example, a tree view click will load one of various screens in the right side pane depending upon which node is clicked - be that a form for entering a survey question or a form for reordering survey sections....

It all works well - a tree view node click leaves the tree view on screen, while the form in the right side pane loads, a cool little loading panel displaying as I wait. But here's the problem...

One operation I want to perform is drag and drop reordering of nodes on the client side - this requires a post back  / server event  so I can refesh the tree view. In this case the tree view will need to do a full post back and completely refresh itself. The problem is that I cannot filter events and therefore when I attempt this my node clicks also beging to do full post backs causing y tree view to dissapear!

The event filter on radajaxmanager does not work, despite (seemingly) conflicting posts I've seen in this forum. And using ajaxManager.ajaxRequestWithTarget and/or ajaxManager.ajaxRequest seems to provide no resolution (mostly errors, limitations and frustration at how little documentation there is on this)

Any help at all would be appreciated ...

How to avoid whole page postback when uncheck the node of radtreeview with Updatepanel
I have a radtreeview inside an UpdatePanel in the bottom there are 3 LinkButton each one inside an UpdatePanel. Each time you uncheck a node the radtreeview do a postback and refreshes the entire page. What I want to achieve is that when you uncheck a node does not refresh the entire page. So I want the buttons are not refresh and if it is possible not to refresh the radtreeview when do the postback. This is the code I use to do that but not working because it refreshes the whole page.

function OnClientNodeChecking(sender, args) {  
        
        if (!args.get_node().get_checked())
        {
            var treeView = $find("<%=trTaxonomy.ClientID%>");  
            treeView.trackChanges();
            args.get_node().set_checked(true);  
            args.set_cancel(true);  
            treeView.commitChanges();
            alert(args.get_node().get_checked());
                        
         }
         if (args.get_node().get_checked())         
         {
            args.set_cancel(true);
         }
      }  
      
      function onNodeChecked(sender, e) {      
        var node = e.get_node();        
        if (node.get_checked()) {
            sender._postBackOnCheck = false;
        }
        
        setTimeout(function() { sender._postBackOnCheck = true; }, 100);

Loop through Grid and find Textbox
Hi

I am trying to write some code which will loop through a RadGrid and find any RadNumericTextBox in the dit template.

The code below works for the first row in the grid but no any others. Any ideas?
Thanks in advance

function ConvertToDegreeMinutesSeconds_Grid(Longitude, Latitude) {
var rgrdRouteWayPoints = $find("<%=rgrdRouteWayPoints.ClientID %>");
 if (rgrdRouteWayPoints) {
                        var MasterTable = rgrdRouteWayPoints.get_masterTableView();
                        var Rows = MasterTable.get_dataItems();
                        for (var i = 0; i < Rows.length; i++) {
                            var row = Rows[i];
         
                            var rtxtLongDegree_Grid = row.findControl("rtxtLongDegree_Grid");
                                                        
                            var rtxtLongMin_Grid = row.findControl("rtxtLongMin_Grid");
                            var rtxtLongSec_Grid = row.findControl("rtxtLongSec_Grid");

                            var rtxtLatDegree_Grid = row.findControl("rtxtLatDegree_Grid");
                            var rtxtLatMin_Grid = row.findControl("rtxtLatMin_Grid");
                            var rtxtLatSec_Grid = row.findControl("rtxtLatSec_Grid");

                            rtxtLongDegree_Grid.set_value(Longitude_Deg);
                            rtxtLongMin_Grid.set_value(Longitude_Min);
                            rtxtLongSec_Grid.set_value(Longitude_Sec);

                            rtxtLatDegree_Grid.set_value(Latitude_Deg);
                            rtxtLatMin_Grid.set_value(Latitude_Min);
                            rtxtLatSec_Grid.set_value(Latitude_Sec);
 
                        }
                    }

                }

                function rcbPortList_Grid_Changed(sender, args) {
                    //copy port long/lat to input boxes
                    var item = args.get_item();
                    var Longitude = item.get_attributes().getAttribute("Longitude");
                    var Latitude = item.get_attributes().getAttribute("Latitude");

                    ConvertToDegreeMinutesSeconds_Grid(Longitude, Latitude);

                }

Show current selected item for RibbonBarMenu
Hi,
I have searched through the API, the demos and the forum, but I have found no
way at all to let a RibbonBarMenu object show it's current selected item (like a
standard DropDownList would do). I'm using a menu like this in the
QuickAccess menu and need to show the current selected item (at least the
text) either on the menu itself or on a label. Is there any way to
accomplish this?

I guess that the following thread is almost the same, except that it's about the ribbonbartogglelist:

Thanks!
