I have wired up an Object DataSource control on the page to do the grunge work for me however when I try to Delete a record my target DeleteMethod does not get the parameters it requires. I have looked around on the help and it looks like the data is supposed to be extracted and available for me to use.

    
            <asp:ObjectDataSource ID="DocLinkViewDataSource" runat="server" TypeName="DocumentsManager" 
        
                    SelectMethod="getDocumentBranchLinkDS" 
        
                    InsertMethod="CreateDocumentBranchLink" 
        
                    UpdateMethod="UpdateDocumentBranchLink" 
        
                    DeleteMethod="DeleteDocumentBranchLink">  
        
                    .......  
        
                    <DeleteParameters> 
        
                        <asp:Parameter Name="BranchDatabase" Type="String" /> 
        
                        <asp:Parameter Name="DocumentID" Type="String" /> 
        
                        <asp:Parameter Name="BusinessType" Type="String" /> 
        
                    </DeleteParameters> 
        
                </asp:ObjectDataSource>

    
            Public Sub DeleteDocumentBranchLink(ByVal BranchDatabase As String, _  
        
               ByVal DocumentID As String, ByVal [BusinessType] As String)

Trouble with RADAjaxManager

I am trying to use RADAjaxManager but when I run my app and cause a trigger, I get the following error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'Manager1"));
});
|<div id="__asptrace"'.

The error is occuring in this code:

    
                function Sys$WebForms$PageRequestManager$_endPostBack(error, response) {  
        
                    // DevDiv Bugs 130268: There could have been a 2nd request that started while this one was being  
        
                    // processed. Detect this by comparing the request for the current response to the _request field,  
        
                    // which stores the latest request that has begun. If they are different, do not clear the state  
        
                    // data that will be required by the 2nd request's response.  
        
                    if (this._request === response.get_webRequest()) {  
        
                        this._processingRequest = false;  
        
                        this._additionalInput = null;  
        
                        this._request = null;  
        
                    }  
        
                    var handler = this._get_eventHandlerList().getHandler("endRequest");  
        
                    var errorHandled = false;  
        
                    if (handler) {  
        
                        var eventArgs = new Sys.WebForms.EndRequestEventArgs(error, this._dataItems, response);  
        
                        handler(this, eventArgs);  
        
                        errorHandled = eventArgs.get_errorHandled();  
        
                    }  
        
                    // DevDiv Bugs 130268: See above  
        
                    if (!this._processingRequest) {  
        
                        this._dataItems = null;  
        
                    }  
        
                    if (error && !errorHandled) {  
        
                        // DevDiv 89485: throw, don't alert()  
        
                        throw error;  
        
                    }  
        
                }

Here is my code:

    
                    <form id="form1" runat="server">  
        
                        <telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

                            EnableHistory="True">  
        
                            <AjaxSettings>

                                runat="server" HorizontalAlign="Left" 
        
                                >

I have left out the Template code for the formview control.

What am I doing wrong?

Button rendering wrong

Hi,
im using RadFormDecorator together with a DIV and some form controls. The issue is that it refuses to render properly. I have the form inside a splitter pane it that might disturbe the issue.

<

telerik:RadFormDecorator ID="RadFormDecorator1" Skin="Web20" runat="server" DecorationZoneID="zonPersonalSettings" />

<

asp:button ID="btnChooseRegion" runat="server" onclick="btnChooseRegion_Click"

Text="Region"/>

<hr />

<asp:button runat="server" Text="LoggaUt" id="Button1"

onclick="btnLogout_Click"></asp:Button>

</div>

The button´s graphics are rendered wrong so its only the left side of the image showing.
(like if it was the same problem on this forum it would only be the green bit on the "Post" buttons here on the forum)

Have i uploaded the graphics wrong somewhere or why isnt my buttons showing? (its the same error or all Skins im using, only left bit showing)

Modal Popup.

Hi Guys,

I am currently trying to build an app that requires a modal div to pop up when a picture is clicked on. I have been trying for 3 days to find something and it doesn't seem to exist!

Microsoft have put something similar in their ajax control toolkit here...

http://ajax.asp.net/ajaxtoolkit/ModalPopup/ModalPopup.aspx

but that one is client side only and doesn't allow you open the popup on a callback/postback and load dynamic controls into the div etc....

Rad Window would be once solution but isn't quite right as I don't need to load content from another page and really need a simple div.

So, a Rad control to make a modal div pop up on postback would be really cool, or if anyone has any other suggestions they would be greatly appreciated :)

_d6.parentNode is null

Hello,

Our first deadline is gone, up to the next one. We discovered a strange error in javascript:

_d6.parentNode is null

_d6.parentNode.removeChild(_d6); on line 5570 of the javascript of telerik.

the code around is as follows:
5557var _d8=now-_d6._startDisplayTime;
5558var _d9=this._minDisplayTime;
5559if(this._isSticky){
5560if(_d9>_d8){
5561window.setTimeout(function(){
5562_d6.style.display="none";
5563},_d9);
5564}else{
5565_d6.style.display="none";
5566}
5567}else{
5568if(_d9>_d8){
5569window.setTimeout(function(){
5570_d6.parentNode.removeChild(_d6);
5571if(typeof (_d2)!="undefined"&&(_d2!=null)){
5572_d2.style.visibility="visible";
5573}
5574},_d9);
5575}else{
5576_d6.parentNode.removeChild(_d6);
5577if(typeof (_d2)!="undefined"&&(_d2!=null)){
5578_d2.style.visibility="visible";
5579}
5580}
5581}

The strange thing is that in debug mode the error does not appear. We see the issticky element so we think it has something to do with the loadingscreens.

the situation where it happens is as follows:
selectedindexchanged on a radcombobox which will update a very simple radgrid on which a loadingpanel is defined.

Any suggestions could be helpfull.

[Solved] RadAJAX SIMPLE example

Hi,

I spent time here to understand how RadAJAX is working but I'm not able to make it working. I tried samples from demos.telerik.com but i do not have ascx files to compile it. In addition, I do not have a database.

Is there really simple solution for a couple of controls? Can one of controls update another? Can server's "on demand" for one control see state of another control without postback?

Thanks in advance,
Eugene

[Solved] Binding to a Formview Control

Hi

maybe this is a newbie question and has been answered in previous threads but after searching around I could not find an answer to my needs.

I have a combobox within a formview. The formview is initially in insert or edit mode. I have a lookup source binded to the combo. I want to be able to bind the value to a db field and on edit mode show the selected value reflecting what is stored in the db.

The formview is using an objectdatasource.

any help will be greatly appreciated.

ContextMenu doesn't display correctly inside of iframe

We recently upgraded from the Q2 2008 release to the Q2 SP2 release. In one instance, we have a radrotator with a context menu that is inside of an iframe. When you right click on the rotator the menu attempts to display, but displays as all white. and covers up anything in the rotator. This was working in the original Q2 release.

The menu is using the Default skin and has 4 items in it. If I run the page that is normally inside the iframe outside of the iframe, the menu renders correctly. In both instances, I can click on the menu (even though I can't see it in the iframe) and it will respond correctly.

Thanks,

Adam
