Adding Tooltips to CheckboxList

Greetings,

I have a checkboxlist on a page to which I am trying to add tooltips to. I finally managed to find some code that placed them onto it during the load of the page, but whenever I do a postback, they will not return, no matter what I seem to do to them. Here is the code for what I'm doing.

    
            //I cut out part of the code that does other things, but this is basically the same  
        
            protected void Page_Load(object sender, EventArgs e)  
        
                    {  
        
                        if (!IsPostBack)  
        
                            //CoP is just a Session variable that is pulled into a property  
        
                            LoadValues(CoP);  
        
                        LoadTooltips();  
        
                    }  
        
            //Called after checkboxlist is built  
        
            private void LoadTooltips()  
        
                    {  
        
                        foreach (ListItem li in cblModules.Items)  
        
                        {  
        
                            var moduleHit = (from a in CoP.Modules where a.ModuleID == Int32.Parse(li.Value) select a.Description).FirstOrDefault();  
        
                            if (!string.IsNullOrEmpty(moduleHit))  
        
                                ToolTipify(li, moduleHit);  
        
                        }  
        
                    }

When the OnSelectedIndexChanged event is fired, LoadTooltips is called at the end to rebuild the Tooltips for the cblModules. Unfortunately, nothing happens. Here is the code I use to build the Tooltips if it helps.

    
            private void ToolTipify(ListItem li, string description)  
        
                    {  
        
                        ContentPlaceHolder con = (ContentPlaceHolder)Master.Master.FindControl("cphContent2");  
        
                        ContentPlaceHolder con1 = (ContentPlaceHolder)con.FindControl("cphCCMContent");  
        
                        RadToolTip tip = new RadToolTip();  
        
                        li.Attributes.Add("ID", Guid.NewGuid().ToString());  
        
                        tip.RelativeTo = ToolTipRelativeDisplay.Element;  
        
                        tip.Text = description;  
        
                        tip.TargetControlID = li.Attributes["ID"];  
        
                        tip.IsClientID = true;  
        
                        con1.Controls.Add(tip);  
        
                    }

Again, it works on the first time through, when there is no Postback, but when I cause a Postback (clicking on cblModules), the tooltips vanish. If anyone has any ideas or a better solution, I'd be very appreciative.

not on top of call stack ?!

Hy i have a rad grid, which im using a RadMenu as a context menu with it. All works fine.

The Radmenu Command calls the method "OpenFile(int id)" in the code behind file to as u correctly guess should opens a already on the server stored file in a file stream to the client.

Heres the method:

    
            private void OpenFile(int id) 
        
                    { 
        
                        try 
        
                        { 
        
                            Document doc = BLDocument.GetDocument(id); 
        
                            if (File.Exists(doc.Metainformation.filepath)) 
        
                            { 
        
                                // Create New instance of FileInfo class to get the properties of the file being downloaded 
        
                                FileInfo file = new FileInfo(doc.Metainformation.filepath); 
        
                                // Clear the content of the response 
        
                                Response.ClearContent(); 
        
                                // LINE1: Add the file name and attachment, which will force the open/cance/save dialog to show, to the header 
        
                                Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
        
                                // Add the file size into the response header 
        
                                Response.AddHeader("Content-Length", file.Length.ToString()); 
        
                                // Set the ContentType 
        
                                Response.ContentType = ReturnExtension(file.Extension.ToLower()); 
        
                                // Write the file into the response (TransmitFile is for ASP.NET 2.0. In ASP.NET 1.1 you have to use WriteFile instead) 
        
                                Response.TransmitFile(file.FullName); 
        
                                // End the response 
        
                                Response.End(); 
        
                            } 
        
                        } 
        
                        catch (Exception ex) 
        
                        { 
        
                        } 
        
                    }

After i reach the Reespnse.End(); line i get following exception:

((System.Threading.ThreadAbortException)(ex)):

{Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

Is there any propertie i have to set to be able to give my user the file / filestream ?
Or what can i do to make it work properly?

thx mario

Javascript error 'this.Slots.Month' is null or not an object

Hi
I have a composite control which contains a DateTimePicker control and other child controls. The composite control is in a visual studio solution which has a class project (for generating the dll of my composit controls) and a web site (for testing the dll). I can run the composite control in the testing web site. However, when I include the dll in my other projects, I got the javascript error

'this.Slots.Month' is null or not an object

when a date or time is selected in the pop up calendar. In debug mode, it stopped in

parseDate:function(_fe,_ff){
try{
var _100=new Telerik.Web.UI.DateParsing.DateTimeLexer(this.get_dateFormatInfo());
var _101=_100.GetTokens(_fe);
var _102=new Telerik.Web.UI.DateParsing.DateTimeParser(this.get_dateFormatInfo().TimeInputOnly);
var _103=_102.Parse(_101);
_ff=this._getParsingBaseDate(_ff);
var date=_103.Evaluate(_ff,this.get_dateFormatInfo());
return date;
} <====== stopped here
catch(parseError){
if(parseError.isDateParseException){
return null;
}else{
throw parseError;
}
}
}

I have no clue about what caused the error. Your help is much appreciated.

RadRotator scroll button issue

Hi.

There appears to be a bug with left button in RadRotator.
I've put up a simple horizontal rotator and I have a problem: when rotator is positioned at page 2 - it allows a user to click the left button more then once before it disables it (for the purpose of reaching the begining of the list). What happens is - if a users clicks the left button more then once fast enough - the list ends up out of bounds. This only happens with the left(previous page) button; right(next page) buttons works properly.

I'd appreciate if I could get some help, if there is some way to work around that bug. Thanks.

Here's an example to reproduce the mentioned issue; first, scroll to page 2 and then click left scroll button a couple of times fast:
(Q2 2009 - 701)

    
            <telerik:RadScriptManager runat="server" /> 
        
            <telerik:RadRotator ID="RadRotator1" runat="server" RotatorType="Buttons" WrapFrames="false" Width="540px" Height="135px" ItemHeight="135px" ItemWidth="135px"> 
        
            <ItemTemplate> 
        
                <div style="background: red; width: 135px; height: 135px;"> 
        
                TEST 
        
                </div> 
        
            </ItemTemplate> 
        
            <Items> 
        
                <telerik:RadRotatorItem ID="RadRotatorItem1" runat="server" /> 
        
                <telerik:RadRotatorItem ID="RadRotatorItem2" runat="server" /> 
        
                <telerik:RadRotatorItem ID="RadRotatorItem3" runat="server" />

                <telerik:RadRotatorItem ID="RadRotatorItem6" runat="server" />

[Solved] ClientSelectColumn Alignment

This is minor issue, but I have always had problems trying to get the ClientSelectColumn checkboxes center justified in their column. I have the following markup for the column:

I thought that it might have to do with some extra padding, so I tried to apply a style that got rid of padding, but that didn't seem to do much. I have to set the column width to at least 40px to get the checkboxes to appear even close to centered. This causes quite a bit of wasted space to the left and right of the checkboxes.

    
            <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" Resizable="False" > 
        
                            <ItemStyle width="40px" HorizontalAlign="Center" VerticalAlign="Middle" CssClass="GridSelectColumnItem" ></ItemStyle>  
        
                            <HeaderStyle width="40px" HorizontalAlign="Center" VerticalAlign="Middle" BorderStyle="None"></HeaderStyle> 
        
                        </telerik:GridClientSelectColumn> 
        
            the style shown is:  
        
            .GridSelectColumnItem   
        
            {  
        
                padding:0;  
        
                margin:0;  
        
            }

Buttons and FileUploads invisible q2 2009

We recently upgraded to the new controls.

I like the drop down styling , but it has made my upload boxes and my buttons vanish from the page. They are still there as I can click where the button should be and it works.

I have chosen not to style buttons as i have my own css - the upload controls do not have any style on them

    
            <telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server"   
        
                    DecoratedControls="CheckBoxes, RadioButtons, Textbox, Textarea, Select" />

here is a screenshot: Missing Items

I am stumped - My solution for now is to turn it off, but I hope we can find a better one.

Error 800a025e occured when using RadEditor in UpdatePanel

Hello,

I have a problem when using editor.

I don't know how to upload the attachment. so i just describe the process.

using UpdatePanel in the page
add 2 buttons in the UpdatePanel ContentTemplate
Button1 used for create the radEditor dynamic
when the editor is shown, input some text in the Editor, select all, change the text color, then click anywhere in the edit area(if keep selected state, the issue will disappear)
Button2 can do anything, just make sure it do the asynchronous postback.
when the result is back, click in the edit area, error 800a025e occured.

I personally think the cursor position make the problem.

Browser:IE7
Version:2008.Q3.SP1

Thanks for your reply.
