Using HistoryPoints in NET 3.5...

I can select the tab in the onnavigate event but since this event occurs AFTER the page_load
I am unable to trigger the server side TabClick event which loads the content of the tabs.

The content of each tab is a user control that is loaded by the TabClick event. This event
is not been fired by the Ajax history onnavigate event.

The onnavigate event does fire the page_load BUT it does it before it executes and sets
the tab.selectIndex property.

Any suggestions/solutions would be most appreciated as usually :)

RadComboBox / AJAX 4.0 Template Keyboard Issue

I have the following:

                    <telerik:RadComboBox ID="healthNumberCmbo" runat="server" AllowCustomText="true"         
            HighlightTemplatedItems="true" EnableLoadOnDemand="true" LoadingMessage="Loading ..." Height="250px"         
            MarkFirstMatch="true" OnClientItemsRequesting="onClientItemsRequesting"         
            OnClientItemDataBound="onClientItemDataBound">         
                 <WebServiceSettings Method="GetPatients" Path="Services/PatientAC.asmx" />         
            </telerik:RadComboBox>         
                     
            <!-- Client-side Data Template -->         
            <div id="myTemplate" class="sys-template">         
                 <b>Name:&nbsp;</b>{{FullName}}<br />                          
                 <b>DOB:&nbsp;</b>{{BirthDate.format("MM/dd/yyyy")}}<br />                                       
                 <b>HC#:&nbsp;</b>{{HealthNumber}}         
            </div>        

                    function onClientItemsRequesting(sender, eventArgs)         
            {         
                var context = eventArgs.get_context();         
                context["filterString"] = eventArgs.get_text();         
            }         
                     
            function onClientItemDataBound(sender, eventArgs)         
            {         
                var item = eventArgs.getItem();         
                var dataItem = eventArgs.get_dataItem();         
                      
                // set the attributes that we can use when they select the item         
                item.get_attributes().setAttribute("healthNumber", dataItem.HealthNumber);         
                item.get_attributes().setAttribute("fullName", dataItem.FullName);         
                item.get_attributes().setAttribute("birthDate", dataItem.BirthDate);         
                     
                // set the value to the ID of the patient         
                item.set_value(dataItem.PatientID);         
                     
                var template = new Sys.UI.Template($get("myTemplate"));         
                template.instantiateIn(item.get_element(), dataItem);         
            }         

I've based my functionality off of the blog post here .. my issue is this:

When the user clicks to open the combo box, and it loads, and they use the UP and DOWN arrows on the keyboard, the text that gets set in the combo box is what was in the template for that item.

How can I use the template, but at the same time - be able to only put the Health Number in the textbox. The reason is that we have clientside validation by using the CustomValidator - and for that to work before you select the item, the text in the box needs to be what i'm expecting.

Case 1: What I currently get in the textbox when the user uses the UP/DOWN keys and doesn't press enter or leave the combo ...

Name: Some Guy DOB: 1/1/2009 HC#: 1234567890

Case 2: What I want in the textbox under that situation:

1234567890

I'm using a validation RegEx of "^\\d{10}$", which obviously isn't valid under Case 1 ..

Help!

call custom FileBrowserContentProvider from ImageEditor.ascx

I have implemented a custom FIleBrowserContentProvider successfully, and have it working with RadEditor.

Is there a way to cause the ImageEditor's Save functionality call a custom FileBrowserContentProvider?

Looks like the 'cannot write to folder' alert is getting hit in the _saveButtonClickHandler in ImageEditor.ascx:

var name = this.get_newImageName()+$get("NewImageExt").innerHTML;

if (!name || name.indexOf(separator) != -1)

{

alert(localization[

"MessageCannotWriteToFolder"]);

return;

}

I have not made any changes to any of this code.

Suggestions?

Error when overring ContentType

Hi

I am generating a CSV file on the fly in my aspx page. RadCompression is giving me an error when processing is done and it is about to send a "application/octet-stream" content type to my page.

Here's my code.

    
                            string strFileContent = sb.ToString(); // This is the CSV string generated 
        
                            // EXPORT 
        
                            string strFile = "export.csv"; 
        
                            string ContentType = "application/octet-stream"; 
        
                            Response.Clear(); 
        
                            Response.ContentType = ContentType; 
        
                            Response.AddHeader("Content-Disposition", "attachment; filename=\"" + strFile + "\""); 
        
                            Response.Flush(); 
        
                            Response.Write(strFileContent); 
        
                            Response.End();

I had to remove RadCompresstion from the web.config to get this working. Thanks.

RadGrid and BoundCombo using EF DataSource

All-
Are there any examples/help out there for this scenario?
I have a few tables that I am loading into some RadGrids for editing.
A few of the columns are really lookup/reference table data. The primary table has foreign keys over to the various reference tables.

I want to show the description(from the reference table) as a label in read-mode. But when it goes to "Edit" mode, switch to boundCombo boxes to allow those lookup fields to be selected from the dropdowns.

Then on the "Update" submit the edited row back for updating.

I am using an EF model for testing but also have some WCF services for the CRUD methods if I need them.

Any help would be great-
MJD

Problem with Monthky Rad chart Control

Hi Telerik Team,
We are trying to make monthly chart in which series are being created Dynamically. On X-axis, we need to group chart with Months Name. I also tried your sample application and also following same steps in my application. But it shows me some inconsistant values (Mean it is not showing values according to proper months). I am selecting records using Linq Entity framework and keep them in Data Table. When i receive records in datatable, data is to be shown properly but when i pass this datatable to my Rad Chart control then it shows some inconsistant values. Can you please guide us that how we can solve this issue.

Regards,
Ascertia Team

question about nestedviewtemplate sample

hello I've started look into nestedviewtemplates and have a couple of question

1. http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx in this sample, the sales grid consists of a detailview table. the sqldatasource has a sessionparameter. Now i Assume that the parenttablerelationship-settings do put the correct value inside there and that it should be asp:Parameter instead - because i cannot see where the session parameter is set.

2. My other question is how to achieve what is done in the nestedview sample programmatically? Using the sqldatasources and binding to the hidden Label to use as ID and then use controlparameter seems pretty okay. But what if there's a scenario where i cannot use the parameterized datasources? I looked into the documentation and found the OnDetailTableDataBind event which i have successfully used to fetch data and bind it to detailtables, but how can it be done in nestedviewtemplates?

i haven't tested the sample extensively but i suppose the fact that nestedviewtemplate consists of tabstrips, detailviews etc adds to the complexity of databinding programmatically?

[Solved] Refresh a WCF-bound grid

Hi,

I have a WCF-bound grid that works fine. I have the user select one or more items, click a button, which opens a Window for editing. All this is fine.

I have an event handler on closing of the window and in this I want to be able to update the grid with the changes. This, however, runs the code but does not retrieve the changes by calling the WCF service.

My JavaScript:

                    var grid = $find('<%=radGridDataGroups.ClientID %>');         
            var selItems = grid.get_masterTableView().get_selectedItems();         
            if (selItems.length == 0) {         
                radalert('Please select an item to edit and then try again.', 300, 100, 'Edit Data Group');         
            } else {         
                for (var i = 0; i < selItems.length; i++) {         
                    var w=migOpenDialog('~/secure/dialogs/system/EditDataGroup.aspx?dataGroupID=' + selItems[i].getDataKeyValue("DataGroupID"), 600, 600);         
                    if (w) {         
                        w.setActive(true);         
                        w.set_modal(true);         
                        w.add_close(function() {         
                            alert('hello');          
                            var masterTable = $find("<%=radGridDataGroups.ClientID %>").get_masterTableView();         
                            masterTable.rebind();         
                        });         
                        w.show();         
                    }         
                }         
            }         

So the 'hello' message is displayed (I have also put breakpoints in there). I have stepped through the $find call, which gets the grid and the rebind method appears to run, but nothing happens.

So how can I refresh a WCF grid based on changes?

Note: migOpenDialog is just a wrapper for your openWindow function.

Many thanks

Adding large amount of items on client side

Hello,

How can i quickly add 5000 items to the list control on client side?

I can use the _addNewItems("", options) in RadComboBox, do you have any similar method in RadListBox control which allows to avoid creating RadListItem javascript objects one by one?

Thanks

Update event not firing

Hi

I have a grid which allows me to edit the row. Updating works fine. However when I use the itemupdated event handler the row does not update. The itemupdated eventworks fires fine though.

Is there something else I must do when I use the itemupdated event or is this a bug?

Thank you
