Global variables being wiped out on Ajax calls

My RadEditor has an Ajax call to save file on webserver as following. The codes are recommended from the documentation:

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

function ajaxRequest(operation)

{

var ajaxManager = <%= RadAjaxManager1.ClientID %>;

ajaxManager.ajaxRequest(operation);

}

</script>

</telerik:RadScriptBlock>

In my code behind file, I have a temp variable:
string temp;

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

if (e.Argument != "Save")

{

return;

}

//Saving content

string content = RadEditor1.Content;

}

protected void Page_Load(object sender, EventArgs e)

{
temp = "123";
}

The problem I'm having is that whenever user hits the save button, the global variable (temp) is wiped out. This is very frustrating...! Could someone help me please? I don't know what to do... Thanks!

Firefox bug with tooltip opacity

I have several links and images in a panel that I put RadToolTips on in this manner:
RadToolTip tpDetailsGuests = new RadToolTip();
                tpDetailsGuests.ShowEvent = ToolTipShowEvent.OnMouseOver;
                tpDetailsGuests.Skin = "Vista";
                tpDetailsGuests.Position = ToolTipPosition.BottomCenter;
                tpDetailsGuests.Width = new Unit("300px");
                tpDetailsGuests.Height = new Unit("250px");
                tpDetailsGuests.OffsetX = 20;
                tpDetailsGuests.Animation = ToolTipAnimation.Fade;
                tpDetailsGuests.Sticky = true;
                tpDetailsGuests.IsClientID = true;
                tpDetailsGuests.ContentScrolling = ToolTipScrolling.Auto;
                tpDetailsGuests.TargetControlID = "showAllGuests";
                tpDetailsGuests.Text = txtGuests.ToString();
                Panel_GuestListing.Controls.Add(tpDetailsGuests);

And since upgrading to the 2009 controls this has stopped working in Firefox. The first mouse over shows this in the bug tracker in firefox
<div id="RadToolTipWrapper_ctl00_PageCode_ctl07" class="RadToolTip_Vista rtVisibleCallout" unselectable="on" style="position: absolute; z-index: 8000; visibility: visible; left: 415px; top: 109px; width: 300px;">

What I have found is that if I mouseover and mouse off before the tooltip finishes loading the opacity stays at a number below one bug tracker shows this.
<div id="RadToolTipWrapper_ctl00_PageCode_ctl07" class="RadToolTip_Vista rtVisibleCallout" unselectable="on" style="position: absolute; z-index: 8000; left: 400px; top: 112px; width: 300px; opacity: 0.0170707; visibility: visible; display: none;">

And once the opacity is set below one, i can't get it back to one to display correctly. This from what my brief testing shows is that it only happens with the Fade ToolTipAnimation. I'm in FireFox 3.0.8.

[Solved] Does RadTabstrip supports multiline text in its tabs?

I know the WinForm version does. What about WebForm version? I've looked everywhere and did not find anything. Do you guys have this feature?

unable to style custom commands with a background image

Hello,

I followed the documentation to replaced default buttons for custom commands, creating a css class like
.dockadd
{
width: 20px;
background: url(/myurl/myimg.gif);
}

then applying it with a CssClass='dockadd' to my custom command.
Something is happening as the image for command changes but it is not the one I set with my class but some kind of inverted V.
I also noticed that change the width in css has no effect on commands size.
Is there something not mentionned in documentation I need to implement ?
I must say that I am also applying the Web20 skin to the dock.

Thanks for help

Hyperlink Manager moving images in tables

Hello -
We recently had several customers complain about a problem when editing hyperlinks on images inside of a table. Making any change to the hyperlink and selecting OK moved the hyperlink and image outside of the <td></td> tags and leaves it hanging inside of the <tr></tr>, which completely messes up the table formatting.

Before HTML:

    
                    <table cellspacing="0" cellpadding="0" border="0" align="center" width="639"> 
        
                        <tbody> 
        
                            <tr> 
        
                                <td width="15">&nbsp;</td> 
        
                                <td width="256"><a target="_blank" href="http://www.webook.com"><img height="87" border="0" width="256" alt="WEbook" src="http://www.bsf01.com/creatives/webook/090107/builds/images/webookLogo.gif" /></a></td> 
        
                                <td width="79"><img height="87" width="101" alt="Wow" src="http://www.bsf01.com/creatives/webook/090107/builds/images/wow.gif" /></td> 
        
                                <td width="289" style="font-family: arial,helvetica,sans-serif; font-size: 16px; color: rgb(255, 102, 0);">&nbsp;</td> 
        
                            </tr> 
        
                            <tr> 
        
                                <td><img height="110" width="15" src="http://www.bsf01.com/creatives/webook/090107/builds/images/r2green.gif" /></td>

                                <td><img height="110" width="101" src="http://www.bsf01.com/creatives/webook/090107/builds/images/r2green2.gif" /></td>

After HTML:

    
                    <table cellspacing="0" cellpadding="0" border="0" align="center" width="639">

                                <td width="256"></td> 
        
                                <td width="79"><img height="87" width="101" alt="Wow" src="http://www.bsf01.com/creatives/webook/090107/builds/images/wow.gif" /></td>

                        </tbody> 
        
                    </table>

Upon investigation, this seems to only happen in Firefox. I'm in the process of investigating other types of hyperlinks inside of tables to see if the problem is more extensive.

Thanks for any assistance.

[Solved] Setting DataNavigateUrlFormatString parameter dynamically

Here is the code snippet from the grid.

    
                                    <telerik:GridHyperLinkColumn DataTextField="EstimateID" UniqueName="EstimateID" HeaderText="Quote #" AllowFiltering="false"  
        
                                            DataNavigateUrlFormatString="~/QuoteDetail.aspx?EstimateID={0}" DataNavigateUrlFields="EstimateID" SortExpression="EstimateID" 
        
                                            SortAscImageUrl="~/Images/SortAsc.gif" SortDescImageUrl="~/Images/SortDesc.gif" ItemStyle-Font-Underline="true"> 
        
                                        <ItemStyle HorizontalAlign="Center" Font-Size="12px" /> 
        
                                    </telerik:GridHyperLinkColumn>

I would like to set the DataNavigateUrlFormatString from a field in the bound datatable, just like the visible text field is set by setting the DataTextField property, or set this property in the code behind before the grid is rendered.

Can this be done and how do I do it??

Thanks!

The 'Â' bug on saving file

I came across an intresting bug that I thought I would share with everyone just incase it is happening to them as well.

When you have saved a file from the editor, if you have a tag, a space and then some text (example below), when saved the 'Â' character appears. This seems to be because a   is missing and is rather replaced with the character code 160.

    
            <td> Some text</td> 
        
            shows as:  
        
            Â Some text

When you view the saved file in notepad/ word pad/ visual studio etc. you do not see the character. If you view it in a hex editor, you do.
A problem only arises if you open the saved HTML file, manipulate it and then resave it because then the character code is picked up and acted on (rendered).

Once I managed to track down the problem, the fix was really quite simple, simply:

Encode the text to HTML
Replace the offending character with a nbsp;
Decode from HTML ready for saving or more manipulation.

    
            string contentData = Server.HtmlEncode(this._RadEditor.Content);  
        
            contentDatacontentData = contentData.Replace("&#160;", "&amp;nbsp;");  
        
            contentData = Server.HtmlDecode(contentData);

I must stress that this bug only appears after you try and manipulate the document by loading it, manipulating it and resaving it (but it did happen on every machine that we tested it on). If you are viewing your saved documents straight off then this should not be a problem for you.

Self Referencing Hierarchy in Programmatic Grid

We are creating the radgrid dynamically in code behind with one bound column and other template columns.

Also, we are using self referencing hierarchy to make heirarchical grid.

We have Autogeneratecolumns=false.

The problem is that level 0 rows are displayed but the child rows are not formed in the hierarchy. It displays 'No child records found'.

Whereas if we don not add dynamic columns and autogenerate them, it works fine.

But we cannot do away with dynamic creation as that is the requirement.

Please provide the solution for same.

Can you please mark a copy of solution to:
