Hello,
I want to print grid content. I refer http://www.telerik.com/support/code-library/print-radgrid-contents this link.
referring this link print operation perform perfectly but I want to remove some attributes of grid like "allowscrolling,usestaticheader etc" at the time of print grid and after print  grid that property again bind to grid.
I am trying this two ways

1.st_approch
On Code Behind
.aspx page

2.nd_approch
.aspx
and the above print code call on button onclientclick event
above both ways not working to achieve the task.
So please tell me how achieve this task.

I have a simple  textbox and a simple dropdownlist like this:
<asp:TextBox ID="txtState" runat="server" Width="200px" AutoPostBack="true"    ></asp:TextBox>
 <asp:DropDownList ID="cboCities" runat="server"  Width="200px" AutoPostBack="true" >  </asp:DropDownList> 

When the user enters a state in the textbox, I want to fill the dropdownlist with appropriate cities. I am using an Open Access Data Model.I have tried several different ways to bind the dropdownlist in the page’s load complete event when it detects that txtState.text <> “” and cboCities.items.count = 0

'Attempt 1
 'No errors but no values filled either. If it did work I would want to replace the where clause with c.State = txtState.text
Using model As New MyDataModel.EntitiesModel
       Dim Stations As List(Of City) = (From c In model.Cities Where c.State = "MA" _ And c.IsActive = 1).ToList
       If Not Stations Is Nothing Then
            cboCities.DataSource = Stations
            cboCities.DataBind()
       End If
End Using

'Attempt 2 
  ''this one works but doesn't have the ability to filter by state. DBContext is defined on the DataAccesPage which this page inherits from
  cboCities.DataSource = DbContext.Cities.ToList()
  cboCities.DataTextField = "CityID"
  cboCities.DataBind()

   'Attempt 3
'THIS ONE WORKS TO FILL THE CBO BUT ANY CODE AFTER THIS THROWS ERRORS I really wanted this one to work because it calls a function in my '     'BLL (FillCitiesList) which seems the most “Proper” way to go about it

Dim listStations As IQueryable(Of CanFillStation)
listStations = FillCitiesList ("MA”)
cboCities.DataSource = listStations
cboCities.DataBind() 

Public Function FillCitiesList (ByVal stState As String) As IQueryable(Of City)
        Using model As New MyDataModel.EntitiesModel
            Dim query = From c In model.Cities Where c.State = strState
               Select c
            Return query
        End Using
    End Function 

This is the error message that is thrown after attempt 3 code executes:
System.ObjectDisposedException was unhandled by user code  Message=The ObjectScope has already been disposed and it's managed persistent objects can no longer be accessed. The ObjectScope should be disposed at the end of the life cycle of your business logic instance.

Obviously, I don't know what I'm doing! Can anyone help me fill the dropdownlist programatically after the user enters a state, using OpenAccess, and preferably using a business layer function?

Thanks

Hello,
I noticed that the PivotTable control is not compatible with touchscreen tablet on Windows 8.
How do I use it better?

Thanks
Francesco

Just curious if it works before investing too much time into it.  I have tried to implement it and have had no luck.  Please advise.

Hello there,

i am using RADtreeview within my User Control (*.ascx). I also configured it to get its nodes from a webservice. So far so good, all is working fine as long as i open the Page with "http://". I see the Control is sending its request with POST to my WebService and gets all needed information to populate the Tree.

But as soon as i switch to "https://" the Control is asking the WebService with GET instead of POST. How to configure it to always send POST?

UseHttpGet="false" doens't change anything. Also my WebService only have a POST OperationContract.

WebService Contract:


User Control (*.ascx):

       Telerik version  =  2014.1.225.40

Hello Guys,

Right now I'm working with my clients to develop an Image viewer, using the components RadImageEditor and RadGrid. The RadGrid is implemented to be the thumbnail part of the viewer and each row is an image of the document, when its clicked loads the image.url to the Image Editor. I'm handling here documents so I want to make annotations, highlights, add text, rotate, crop, all the basic operations that an image viewer do. But I'm having some troubles. 1) The memory consumption its to high when each image is loaded, here its a script that change the route of the image with ajax, the image editor consumes more and more memory, there is an option to dispose the memory or maybe I'm loading wrong the images? 2)  The images are loaded fine in the beginning, and when you click each image I just change the image URL, also my images are in a share folder so all my access are fine, but when i try to do some operations of the Image Editor a java exception raises and the operations dialog are not loaded fine and don't work.

Do you have some tips to handle this better?

Thanks,
Javier

Hi,
Referring to the screencap http://upload.ximnet.com.my/huisheng/crop.png

Requirement: I want to let user crop a 300x300 thumbnail:

1. I have locked the width and height and hide the aspect ratio using JavaScript:



2. But if user drag the resize handler, they are still able to change the thumbnail size.
How do I lock the resize handler to prevent user from re-sizing when cropping?

3. What is the best way / correct way to load the thumbnail size from database?  Is it to use Ajax call in the ascx or there is a better method?

Thanks.

Is there any way to hide the pager control in a rad pivot grid.  I see that it is possible in normal grid but I am not sure how to do this in a pivot grid.

Thanks
