Hi, I am trying to use a RadListView in the same way I use a RadGrid in that I am trying to get the datakeyvalue for a specific dataitem when in the ItemDataBound method.

In a RadGrid, I can do the following:

    
            e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex][myDataKey]

to get the value of each datakey and then set client-side onclick attributes for a hyperlink so that clicking the link opens a RadWindow, passing in the row ID.

However, e.Item for a RadListView does not have an ItemIndex property, so how can I do the same for a RadListView?
ie,

e.Item.OwnerListView.DataKeyValues[???][myDataKey]

Regards,
Jonathan

Excel like grid - Again

Hi all,

I am new to Telerik RadControls for ASP.NET.

I want to create a Excel like grid. Without the need to click the "Add" hyperlink to add a row. Without the need to click "Edit" link to edit a record... etc.

I have checked the forum and code library. Its has a very simular thread in the code library but its old - seems its from old version Rad controls and its for ASP.NET 2.0 anyway.

I thought the excel like grid is a very popular thing to do but seems not many people are talking about it. Is it a reason for that?

Also can I please ask if anyone has done it in the lastest RadGrid and in ASP.NET 3.5 and able to provide some sample for me.

The grid itself seems unable to do it and it seems to need to wrap with something controls but I don't have a clue.

Please help.

Treeview SelectedNode.Value

Hi,

i've got a problem using the RadTreeView.

I have a simple RadTreeview, which send some Javascript Arguments to a RadXmlHttpPanel using OnClientNodeClicked:

    
              function OnClientNodeClicked(sender, args) { 
        
                         var node = args.get_node(); 
        
                         node.select(); 
        
                         var panel = $find("<%=RadXmlHttpPanel1.ClientID%>"); 
        
                         panel.set_value(node.get_value()); 
        
                     } 
        
              <telerik:RadXmlHttpPanel ID="RadXmlHttpPanel1" runat="server" 
        
                                  Value="EMPTY" 
        
                                  LoadingPanelID="RadAjaxLoadingPanel2" 
        
                                    OnServiceRequest="XmlHttpPanel_ServiceRequest" 
        
                                    Height="180px" 
        
                                    Width="280px" 
        
                                    EnableClientScriptEvaluation="true" 
        
                                   ></telerik:RadXmlHttpPanel>

It works well.

But i have to add another RadXmlHttpPanel under this one with a RadGrid inside (Following Telerik sample).

I put a OnNeedDataSource="RadGrid1_NeedDataSource" on my RadGrid in order to fill it, and i tried this in code behind:

    
            Dim s As String = RadTreeView1.SelectedValue 
        
             RadGrid1.DataSource = MyFunction(s)

But it fails. i've trying to find a solution for 2 days now, but i don't know how to catch my treeview value. Any help? thanks

RadScriptManager + AJAX + Embedded Scripts

I am having an issue with AJAX (and only AJAX calls) calls when using embedded scripts that are compiled into a DLL. For example, RadTabs work fine, but when loading a user control via AJAX, I get an error. Likewise loading a user control via AJAX for a ToolTip gives me an error.

The error being returned is:

RadToolTipManager response error:
Exception=Sys.WebForms.PageRequestManagerServerErrorException: Assembly 'JPScriptResources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not contain a Web resource with name 'JPScriptResources.jquery-1.3.2.min.js'.

I can verify that the embedded jQuery IS working in my site, as it works in several other places. I even removed jQuery from embedding, and it just errors on whatever the next embedded script is.

Any thoughts?

ContentURL Transparent Background

I have a radsplitter as followed:
Left Pane : Treeview
Right Panel : Uses the "ContentURL"

I need the page being loaded into the right panel contenturl background to be transparent so that it doesnt overlap the background set for the right panel.
How may I go about this?
Thanks in advance.

- Update -
How do I had "allowTransparency=true" to the iframe generated by radsplitter? This is what I need to get the transparent to work in IE.

Https error: Access is denied

Hi,

I have a problem on my live site using radwindow resize method, on the testing server (without https) the resize is working fine, but on the live server it generates javascript error on the resize method: Access is denied.

http://testv3.reservation-system.net/BE/MapDirections.aspx?hotelcd=HT05003566&langcd=en&htlcccode=HCC0600029

Click on the map picture to popup the radwindow, I've tested this case on IE, Firefox, and Google Chrome, in IE we can see the javascript error detail: Access is denied, but in Firefox and Chrome the javascript error is ignored but the resize is also not working.

Please advise as we cannot find any solution but to turn off the resize, but this solution is not acceptable.

Best regards,

Omar S.

User control as shared DLL

HI ,

I would like to know if there exists a sample which demonstrates an implementation of user control based on some telerik control, exposed as a DLL ?

I mean that I need to create a user control which could be given to developer as a DLL only.

The one of many problems that I see is sharing of e.g. rad script manager .

Can telerik team provide a simple example of such a control ?

thanks in advance !

[Solved] Custom Dialog Insert Duplicating Markup

I’m implementing a Custom Insert Link Dialog, but have run into a problem.

When I insert a link from my custom dialog it insert the new link and the original link (without any contents with argument parameters used)

IE 8
Original editor source:

    
            <p><a href="/link.htm">link text</a></p>

Source after Insert:

    
            <p><a href="/link.htm">link text</a><a href="/link.htm" SKS="bd274b09-7e8d-4802-8edb-f739b2fd00c1" SiteID="1294" PeopleID="12459" newHref="/link.htm"></a></p>

All element properties are properties of the dialog argument object.

Firefox – OK

Chrome and Safari 4
Original editor source:

    
            <p><a href="/link.htm">link text</a></p>

Source after Insert :

    
            <p><a href="/121212.htm"><a href="/121212.htm">test of v8 style link</a></a></p>

Steps I Take
Highlight link

                                // Set argument as link this will be passed into popup
