Hello,

I am trying to evaluate the client-side databinding using WCF and am having a hard time getting the desired results. It appears that I have everything working correctly, and in Firebug I can see that the data is being returned from my WCF method, but it's not showing up in the grid. Also, it is returning the correct number of rows(it is showing the correct paging information and total row count) but is ignoring the pagesize property. Here are some snippets:

    
            <telerik:RadGrid  
        
                        ID="rgTasks"

                        AllowPaging="true"  
        
                        ShowHeader="true" 
        
                        ShowStatusBar="true"

filters during postback on client-side databinding

Am I right that filters set on a client-side databound radgrid are not preserved during a postback?

Currently I have my own buttons to set a filter on the grid. When I press one of the buttons, this client-side function is called:

                    function actionFilter(obj, value)         
            {         
                var tableview = grid.get_masterTableView();         
                tableview.filter('Action', value, 'EqualTo');         
                         
            }         

I have one column which causes a postback. After the postback, the filter is gone and all records are shown. So if I want to preserve the filter, I have to save it programmatically?

How to localize PageSize in Pager in Codebehind?

Hello,
I have a NextPrevAndNumeric pager in a grid and I wanted to localize the text for the label that says "Page size:", but I cannot seem to find out how to do this.

Is it in PagerStyle? Somewhere else? Does this have to be done using a FindControl of the label on the ItemCreated event (I am already creating the grid programatically on Page_Init).

Last Paragraph Not Formatting Properly When Pasting

Hello,

A site I am working on has people to copying and pasting articles into the Editor. I'm trying to make it so people can simply paste a whole article from Word or the like and each paragraph in Word will be wrapped with paragraph tags in the HTML. I essentially have it set up how I want it (with NewLineBR="false" and stripping some other stuff out), except the last paragraph doesn't get wrapped in the paragraph tags. The person can hit Enter every time after the last paragraph (which does wrap it in the paragraph tags), but I can't expect everyone to do that.

This also happens when they aren't pasting the content in. If they type out (rather than paste) a summary, for example, the last paragraph is not wrapped in paragraph tags. Again, if the person hits Enter then it wraps it with the paragraph tags.

Basically, here's what people currently have to do:

Paste the article in from Word
Hit Enter to correctly wrap the last paragraph in paragraph tags
Submit

I'm looking to trim out the part where people have hit enter after pasting in their article. Here's how I have one of the Editors set up:

    
            <telerik:RadEditor StripFormattingOptions="MSWordRemoveAll, css, span" OnClientPasteHtml="StripCharacters" OnClientLoad="DeveloperDescriptionCounter" SkinID="DeveloperDescription" runat="server" ID="editor" AllowScripts="false" NewLineBr="false" ToolsFile="~/App_Data/Editor/EditorToolbar.xml" CssClass="description"> 
        
                <Content></Content> 
        
            </telerik:RadEditor>

I'm not sure if that helps at all, but I figured it wouldn't hurt to include it. I should probably re-mention that every paragraph, except for the last one, works fine.

Thanks,
Nathan

RADGrid markup reformatted in Visual Studio

Is there any way to have the markup for Telerik controls like the RADGrid not be reformatted by Visual Studio? It seems to be removing whitespace to conserve space but this is really annoying when trying to view and edit the aspx.

New Exporting Buttons and Help

Hello,

Is there some documentation on the new buttons and the events associated with them? Any tutorials on how to get exporting working from the ground up with the new buttons? That would be very helpful right now. I'm looking at videos created last year on grid exporting and I don't want to add this feature to the project until I know what I'm doing and if this old video still matches up with the newer releases.

Thanks for any help,
Heath

[Solved] Drag/Drop rows from table with template column

I have a page that supports dragging and dropping rows between two RadGrids. Initially, this worked as expected, but I've now added a GridTemplateColumn to the tables, and now when I try to drag, it just selects the text within the column. If I grab the row at the far left edge, it still selects the row and drags normally.

Is there a way in this case to make the template column work the same way as other columns?

Thanks,
Andrew

            <telerik:RadCodeBlock id="CodeBlock1" runat="server">  
        
            <script type="text/javascript">  
        
            var g_bPaused = false; // To track pause button state;

            function InitMDP()  
        
            {  
        
                try  
        
                {  
        
                    document.getElementById("btnPause").disabled = true;  
        
                    document.getElementById("btnStop").disabled = true;  
        
                    if (document.getElementById("Player").object.enabled )  
        
                    {  
        
                    document.getElementById("Player").uiMode = "none";  
        
                    }  
        
                    }  
        
                catch(ex) {  
        
                    alert(ex);  
        
                    if ( document.getElementById("Panel1") )  
        
                        document.getElementById("Panel1").display=true;  
        
                }  
        
            }

I get an exception in InitMDP "Player" 'has not this property' (but it works in IE), even trying to delay its execution in codebehind using

    
                    protected override void OnPreRender(EventArgs e)  
        
                    {  
        
                        string scriptString             = "InitMDP();";  
        
                        if ( HasAjaxManager )  
        
                        {  
        
                            // We must execute this on end of page loading by browser  
        
                            AjaxManager.ResponseScripts.Add(scriptString);  
        
                        }  
        
                        base.OnPreRender(e);  
        
                    }

I don't understand, am I stopped by some FF feature ?

Thanks for idea.
