Microsoft.Ajax axd files does not cache/ return 304

I have the following settings

1. web.config

        <system.web.extensions >
<scripting ><webServices/>

<scriptResourceHandler
       enableCompression="true"
       enableCaching="true" />
</scripting >

</system.web.extensions >

2. compilation debug = false in web.config and master page

3. <telerik:RadScriptManager ID="ScriptManager" runat="server" ScriptMode="Release" EnableScriptCombine="false" CacheSettings-Enabled="true" /> in master page.

However if i enable cdn, cdn is able to server 304, I assume it is because the files are static in the CDN.

Can Telerik support advise howw to make axd return 304?

Thanks.

HTML Code

<table class="normal_grid">

<tr>

<th style="width: 17%">

<asp:Label ID="lblemployeename" runat="server" Text="Employee Name"></asp:Label>

</th>

<td class="field" style="width: 17%">

<telerik:RadListBox runat="server" ID="rlbemployeename" EnableDragAndDrop="true"

Width="150px" Height="150px" OnClientDropped="lbemployeenamedropped">

</telerik:RadListBox>

</td>

<th style="width: 16%">

<asp:Label ID="Label1" runat="server" Text="Project Admin"></asp:Label><span class="hlt_txt">*</span>

</th>

<td class="field" style="width: 17%">

<telerik:RadListBox runat="server" ID="rlbadminname" EnableDragAndDrop="true" Width="150px"

Height="150px" OnClientDropped="lbadminnamedropped">

</telerik:RadListBox>

</td>

<th style="width: 16%">

<asp:Label ID="Label2" runat="server" Text="Project Reader"></asp:Label><span class="hlt_txt">*</span>

</th>

</telerik:RadListBox>

</td>

</tr>

</table>

Javascript Code:

function lbemployeenamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

function lbadminnamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

function lbreadernamedropped(sender, args) {

transferManager.performTransfer(sender, args);

}

(function ($) {

transferManager = function () { }

debugger;

transferManager.performTransfer = function (sender, args) {

var destinationItemIndex = this._getDestinationIndex(args);

var destinationListBox = this._getDestinationListBox(args);

if (destinationListBox == null)

return;

var reorderIndex = args.get_dropPosition() == 0 ?

destinationItemIndex : destinationItemIndex + 1;

var items = args.get_sourceItems();

this._transfer(items, destinationListBox, reorderIndex);

}

transferManager._transfer = function (items, destination, reorderIndex) {

$.each(items, function (index, item) {

item.unselect();

destination.get_items().insert(reorderIndex, item);

});

}

transferManager._getDestinationIndex = function (args) {

var destinationItem = args.get_destinationItem();

if (destinationItem)

return destinationItem.get_index();

return 0;

}

transferManager._getDestinationListBox = function (args) {

var destinationItem = args.get_destinationItem();

if (destinationItem) {

var id = destinationItem.get_listBox().get_id();

return $find(id);

}

var parent = $(args.get_htmlElement()).parent();

if (parent.is(".RadListBox")) {

var id = parent[0].id;

return $find(id);

}

else if (parent.is(".rlbGroup")) {

var id = parent[0].parentNode.id;

return $find(id);

}

})($telerik.$);

[Solved] retrieve client side id of selected row (DataKeyValue)

Hi,

i got a grid in a radwindow and i want to return the id of the selected row dataitem.
The id is in the MAsterView DataKeyvalue and i also tried to put it in a invisible column with unique name id..
I want to do it client side with java script as i already have used JS by opening the Radwindow.

After i read the references in the online documentary i got following code:

    
            <telerik:RadCodeBlock ID="radCodeBlock" runat="server"> 
        
                        <script type="text/javascript"> 
        
                            function GetRadWindow() 
        
                            { 
        
                               var oWindow = null; 
        
                               if (window.radWindow) oWindow = window.radWindow; 
        
                               else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; 
        
                               return oWindow; 
        
                            } 
        
                            function returnToParent() 
        
                            {                   
        
                                //create the argument that will be returned to the parent page 
        
                                var oArg = new Object(); 
        
                                //get the selected id from RadGrid 
        
                                var grid = $find("<%=radGrid.ClientID %>"); 
        
                                var MasterTable = grid.get_masterTableView(); 
        
                                var selectedRows = MasterTable.get_selectedItems(); 
        
                                for (var i = 0; i < selectedRows.length; i++) 
        
                                { 
        
                                  alert(i); // got 0 for 1 selectec row 
        
                                  var row = selectedRows[i]; 
        
                                  var cell = MasterTable.getCellByColumnUniqueName(row, "id") 
        
                                } 
        
                                var id = cell.innerHtml(); 
        
                                //var id = $find("<%=radGrid.ClientID %>").get_masterTableView().get_selectedItems()[0].getDataKeyValue("id"); 
        
                                //get a reference to the current RadWindow 
        
                                var oWnd = GetRadWindow(); 
        
                                //Close the RadWindow and send the argument to the parent page 
        
                                if(id) 
        
                                { 
        
                                    //oWnd.close(oArg); 
        
                                    alert("docid = " + id); 
        
                                } 
        
                                else 
        
                                { 
        
                                    alert("Please select a document."); 
        
                                } 
        
                            } 
        
                        </script> 
        
                    </telerik:RadCodeBlock>

AcceptTrackChanges() - Server Side

Hello,

I am currently using version 2016.1.225.35 and I'm having issues with the server side AcceptTrackChanges() method. When the method is used it seems that formatting changes that have been made to the content (i.e., Bold) are not accepted. Other changes, like insert and delete, are accepted. I believe this use to work properly in the 2015 version. If we enable the command using the editor toolbar button (<telerik:EditorTool Name="AcceptAllTrackChanges" />), all changes are accepted (including the formatting changes).

To reproduce this problem, include the editor in the page markup. Also, add a Button with the associated OnClick event. Within the code behind OnClick event, utilize the AcceptTrackChanges method to accept changes. Example is shown:

protected void ButtonAcceptChanges_Click(object sender, EventArgs e)

{

RadEditorDesc.AcceptTrackChanges();

}

Make changes within the editor content. Include formatting changes (i.e., bold) and then click on the Accept Changes button. You should notice that all changes are accepted other than formatting type changes.

Any help in resolving this issue would be appreciated.

Thank-you.

[Solved] Zeros are trimmed

Hi,

At our company we created and maintain a large ASP.NET application which makes extensive use of the Telerik Rad controls. We use version 2013.3.1015.40.

Currently we run into an issue with the RadEditor. It occurs in Internet Explorer 11 which is mainly used by one of our customers. If a line starts or ends with zeros (0) and the user presses enter, then those zeros are trimmed. It is very easy to reproduce in an empty web application project.

Steps to reproduce:
Step 1: Type first line starting with a zero or/and ending with a zero.
Step 2: Press ENTER to move to the second line
Step 3: See the zeros disappear in the first line.

We also tried it with the latest version of the Rad controls and there the problem does not occur.

We are aware that we are using an older version, but for our product it suits fine. We are afraid that replacing the Rad controls with the latest version will introduce new bugs or styling issues in our product. It would require a huge amount of QA work and probably a lot of rework.

Can you please help us out? It seems like such a minor issue in the JavaScript code. Maybe you can provide us with a work around or a hotfix. We would greatly appreciate that.

Thanks,
Ronald
