thank's for reply . 

Hello guys,

Really love the FileExplorer, but I'd like to tinker with the Thumbnails functionality. In its current state the thumbnail is just a link to the original image. Since I use the FileExplorer control to serve up a gallery of hi-res stock images, my page basically downloads twenty-megabyte JPEGs as "thumbnails". This also results in ugly compression artifacts and distortions as the browser uses its own algorithm to compress the image.

Is there any way to override the thumbnail display functionality either on the client side or on the server side? For example, if I could point the thumbnails to an ASP.NET handler instead of the images themselves I'd be all set to go since I could perform my own high-quality resizing on the server side and serve up small, good quality thumbnails.

Any ideas?

Hi,

 For ex, I am getting the output from editor.get_html() like "aaa <span class='masked'>bbb</span> ccc". I need the index of ccc from the html which i got from editor. Please share it.

Is it possible to save the entire RibbonBar in a Session variable and use it on page load?
I tried the following but on PostBack it fails.

public void InitRibbonBar(ref RadRibbonBar ribbonBar, string formName, int userLevel)

 

{

 

    CriteriaOperator filter;           

 

    filter = CriteriaOperator.Parse(String.Format("FormName = '{0}'", formName));

 

  

 

    XPCollection _xpoObjects = new XPCollection(DbUtils.GetDefaultSession, typeof(XPOMenuSettings), filter, null);

 

  

 

    SortProperty TabSortOrder = new SortProperty("TabSortOrder", DevExpress.Xpo.DB.SortingDirection.Ascending);

 

    _xpoObjects.Sorting.Add(TabSortOrder);

 

  

 

    SortProperty GroupSortOrder = new SortProperty("GroupSortOrder", DevExpress.Xpo.DB.SortingDirection.Ascending);

 

    _xpoObjects.Sorting.Add(GroupSortOrder);

 

  

 

    SortProperty sortOrder = new SortProperty("SortOrder", DevExpress.Xpo.DB.SortingDirection.Ascending);

 

    _xpoObjects.Sorting.Add(sortOrder);

 

  

 

    RibbonBarTab rbt;

 

    RibbonBarGroup rbg;

 

  

 

    foreach (XPOMenuSettings _xpoButton in _xpoObjects)

 

    {

 

        bool rbt_found = true;

 

        bool rbg_found = true;

 

          

 

        rbt = ribbonBar.FindTabByValue(_xpoButton.TabValue);

 

        if (rbt == null)

 

        {

 

            rbt = new RibbonBarTab();

 

            rbt.ID = _xpoButton.TabId;

 

            rbt.Text = _xpoButton.TabText;

 

            rbt.Value = _xpoButton.TabValue;

 

            rbt_found = false;

 

        }

 

  

 

        rbg = ribbonBar.FindGroupByValue(_xpoButton.GroupValue);

 

        if (rbg == null)

 

        {

 

            rbg = new RibbonBarGroup();

 

            rbg.ID = _xpoButton.GroupId;

 

            rbg.Text = _xpoButton.GroupText;

 

            rbg.Value = _xpoButton.GroupValue;

 

            rbg_found = false;

 

        }

 

  

 

        RibbonBarButton rbb = new RibbonBarButton();

 

        rbb.Size = (RibbonBarItemSize)_xpoButton.Size;

 

        rbb.Text = _xpoButton.Text;

 

        rbb.Value = _xpoButton.Value;

 

        rbb.ID = _xpoButton.Id;

 

        rbb.ImageUrl = _xpoButton.ImageUrl;

 

        rbb.ImageUrlLarge = _xpoButton.ImageUrlLarge;

 

        rbb.Visible = _xpoButton.Visible && (_xpoButton.UserLevel >= userLevel);

 

  

 

        rbb.Width = 80;

 

  

 

        rbg.Items.Add(rbb);

 

        if (!rbg_found)

 

            rbt.Groups.Add(rbg);

 

        if (!rbt_found)

 

            ribbonBar.Tabs.Add(rbt);

 

    }

 

}

Clientside works fine, but as soon as I click a button that calls serverside, I get the following error message:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

this event does not execute when i did double click on radlistboxitem, Why?

I need help!!

Hi All,

I've not had much experience with the rad controls, but what I see so far is pretty good.

I did some searching online, but either was using the wrong search terms or what I want to do is not possible.

I have a listbox on a page.  What I want to do is bind it to a linq datasource with checkboxes filled in from the datasource.

I'm hoping that I can pass in a datasource with 3 columns:

ReceivedEmail: Boolean
ClientID: Int
ClientName: String

True-1-Fred Smith
True-2-Betty White
False-3-Amy Whinehouse

This would produce a list with the three names and the first 2 items checked without any extra work in code...

I was talking to one of the other guys I work with and he said that he usually binds to a datasource and then loops through all the list items after binding has finished and then sets the checked flag..
This seemed a little inefficient, and figured that if the control handled it, why not do it in one go..

Does this make sense..??  Can it be done already..???

Many thanks

hi ,
kindly help me when i used drag drop in rad grid the destination grid sometimes =null 
i used this demo
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/draganddrop/defaultcs.aspx 

and args.get_destinationHtmlElement().id sometimes = the row that i selected it to drop it not the destination element 
even if  i dropped it at  the destination grid .
kindly help me ,
if i got the row index that i dropped on it i will solve my problem ,
how to get it ,
i tried all the methods
http://www.telerik.com/help/aspnet-ajax/grid-onrowdropping.html 
 

I hope this is the right place to post this.  We just purchased the DevCraft Complete (Formerly Premium Collection) and I want to install the RadControls for ASP.NET AJAX and create a web form with a Grid.  The Grid is what I need primarily right now.  I've got a set of webforms with regular ASP.NET 4.0 GridViews, but our staff wants the Header and a couple of columns frozen in place when they scroll the large grid.

Anyway, my question is, "How do I get started?"  I've downloaded the Telerik.Web.UI_2012_2_724_Dev.msi file and some other files.  Do I just run the .msi file to install it in Visual Studio 2010 and then start dragging controls onto my page? 

I've got a new website with just a new Default.aspx page in it right now.  I'll do some testing and playing around here, then if possible I'd like to upgrade my existing webforms that have the .Net GridViews.  I imagine I'll have to replace the old GridViews with a new RadControl Grid.

Are there any "gotchas" that a newbie would need to know about?  Should VS be closed when I install it? 

Thanks!


I see no one wants to comment.  :(   I'm not asking for anything but advice, pointers, suggestions or just general comments.  I'd even be happy with a, "Good luck with that."
