Dear Telerik Team,

I have a page with RadGrid control which has some bound columns and GridButton column which is for delete (having inner) item in grid. Open a popup when click on command item link button and it has a tabstrip which has three tabs. In third tab we have a grid which has to ask radconfirm on OnClient event when click on Generate command item Link button. If OK it has to fire event and do some operation. I tried with all the ways from the articles,forum and documentation source but i didn't. At last i tried with the below script which is working fine but i am unable to fire Delete in Grid.

    
            <script language="javascript" type="text/javascript">     
        
                    var oldConfirm = radconfirm;        
        
                    window.radconfirm = function(text, mozEvent, oWidth, oHeight, callerObj, oTitle)        
        
                    {        
        
                        var ev = mozEvent ? mozEvent : window.event; //Moz support requires passing the event argument manually        
        
                        //Cancel the event        
        
                        ev.cancelBubble = true;        
        
                        ev.returnValue = false;        
        
                        if (ev.stopPropagation) ev.stopPropagation();        
        
                        if (ev.preventDefault) ev.preventDefault();        
        
                        //Determine who is the caller        
        
                        var callerObj = ev.srcElement ? ev.srcElement : ev.target;        
        
                        //Call the original radconfirm and pass it all necessary parameters        
        
                        if (callerObj)         
        
                        {        
        
                            //Show the confirm, then when it is closing, if returned value was true, automatically call the caller's click method again.        
        
                            var callBackFn = function (arg)        
        
                            {                   
        
                                if (arg)        
        
                                {                   
        
                                    callerObj["onclick"] = "";                  
        
                                    if (callerObj.click) callerObj.click(); //Works fine every time in IE, but does not work for links in Moz        
        
                                    else if (callerObj.tagName == "A") //We assume it is a link button!        
        
                                    {                                                               
        
                                        try       
        
                                        {        
        
                                            eval(callerObj.href)        
        
                                        }        
        
                                        catch(e){}        
        
                                    }        
        
                                }        
        
                            }        
        
                            oldConfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);      
        
                        }        
        
                        return false;        
        
                    }       
        
                </script>

Can you please go through this issue and give me a better solution.

Telerik not compatible with asp.net 4.0?

I have a asp.net 3.5 web application and I use a lot of telerik controls in the application.

The web application runs with no problem on asp.net 3.5, but after I converted it to asp.net 4.0, it compiles with no problem, at run-time, I get such errors

ASP.NET Ajax client-side framework failed to load.
'Sys' is undefined
'Telerik' is undefined

1 comes from

<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
//]]>
</script>

in the generated html source.

I see that someone else has exactly the same problem at http://forums.asp.net/p/1486516/3512204.aspx#3512204

So, it seems to me that telerik controls are not compatible with asp.net 4.0. Could your team please give me a solution to this problem? Thank you.

Issues in using Linq2SQL in RadGrid

Dear All,

I've planned to use Linq2SQL for building my data access component and for a requirement, i've selected RadGrid as it provides out-of-box features like grouping, filtering, sorting & hierarchical displays with no code. In order to achieve this i being forced to use SQL Data binding components instead of using Linq2SQL statements. So is there a way to acheive all the above mentioned features using Linq2SQL?

Cheers,

sathish

[Solved] evaluate js from control which is in string

Hi all.

Webservice renders a control and returns it in string. Using js when I paste it on the page, the javascript functions are not evaluated. How can I do that?

In Telerik XmlHttpPanel there is a EnableClientScriptEvaluation. How to do it without using this control?

Labels for multiple pie charts

Is it possible to have a label with each pie chart to indicate which series it represents? I have to display two pie charts in one graph, and it will not be obvious to the user which pie chart represents what data. So I need to add a label (above or beneath) each pie chart with (for example) the series name, or preferably a custom title.
Trying to add items to the X or Y axis does not seem to work, since the axes are not displayed as soon as I set the type of each series to pie. And I could not find a label on the series either.
Is there a way to do this? Thanks...

RadTooltip problem in GridView

Hi All,

I'm facing a problem with Radtooltip. I have a gridview in my page that contains more than 200 rows and I've got a Radtooltip assigned for elements of each column. I'm unable to set the position of tooltip. Sometimes it appears at the extreme bottom of the page, sometimes at the top and at times it doesn't even appear.

Any help will be appreciated.

Thanks

Show/Hide Columns issue

Hello Telerik Team,

I have a radgrid which is programatically created, columns added during page init, exactly as shown in the demo.

Everything in this grid works perfectly but the show/hide columns-function in the headercontextmenu.

What could be a reason for this? When I click the checkbox in the menu, the menu simply closes again, and the display state of the column is not changed

best regards

Ulrik
