How can I place a button in the first header cell above the row selection arrows?  I would like to do this in a class derived from gridview.

Hello,

I have a menu item with image
I wish to check on/off the menu (highlight the image) when the user click on it (same like with the toolbar check button - when the button is checked the image is highlighted)

I used the tooglestate property but this works only without image

Thanks

Hello, 

I use OS: Win 8.1
         .Net4.5
        UI fo Winforms Vers. 2014.2 715 

I try to make a relation between 2 tables in my MS Entity (Framework 6.0.1),

The problem is the tables don't have a column in common so that i can make a direct relation,

What i need is a possibility to .Join a third table to my parent which provides the missing column.

My 3 tables are

tbl_AffiliateCommision which should be my parent template in the Hierarchygridview this table provides me the column "AffiliateUser" and the grouping would be done with this column.

tbl_Affiliate in this table every AffiliateUser gets his specific "IdAffiliates". This table would provide both columns. This table should not be shown in the grid

ItemAffiliate which should be the child template and  provides me the sold items and the column "IdAffiliate" which is a undergroup of the Column "AffiliateUser" ( AffiliateUser is not available in this table)

e.g.: AffiliateUser : 12354 has the IdAffiliates: 1,4,6
         AffiliateUser: 32145 has the IdAffiliates: 2,3,7

Here some code for better a understanding 

in the 01 line i just look up the data i would use the same Join in teh 02 line if it would work like this. 
the rest of the code shows how i would make my grid.

Please let me know if i forgot to give you important information.



best regards 

Greetings, 

I have the following problem: 

He was working on a project but unfortunately I had to reinstall my operating system. Telerik reinstall VisualStudio but normally and continue with my project out the following errors:

Error 10 'TextRenderingHint' no es un miembro de 'Telerik.WinControls.RootRadElement'.

Son 23 errores como el anterior en diferentes formularios, habia mas errores pero agregué unas referencias de telerik y se solucionaron. Pero con ese error no se que hacer 

Yo uso Visual Studio 2012  y VB.net

I would like to add a picture button over the internet.

Example:
PictureBox1.ImageLocation = "http://www.example.com/image/image.jpg" (png better though)

I want to:
RadGalleryItem1.Image = "http://www.example.com/image/image.png" (such as)

How do I make it?

Hi,

I am evaluating the RadScheduler using the Timeline view to display a 24 hour range.
All the scheduled activities occur in 5 minute increments (00:00, 00:05, 00:10, 00:15 etc).

Right now the RadScheduler shows 15 minutes as the minimum timescale for display.

Can I create a custom timescale that would get me down to 5 minutes?

Thanks.

I have a RadPageView control in ViewMode = Strip (so it appears like a TabControl)

I would like to somehow have multiple Images for the RadPageViewPage - one that represents the actual document icon, and another that is only shown when there are unsaved changes. 

Just as an example, take a look at the following screenshot of Visual Studio:
http://i.stack.imgur.com/dPEq0.png

Is this possible?  Any ideas how I can accomplish that? 

I don't have any problem getting one Image to show up (using the RadPageViewPage.Image property) but how would I go about getting the second one to appear?

Thank you!

I would like to change the background color of a row when a certain task is being performed.  Once that task has completed I would like to change it back.  All the examples I have found subscribe to the RowFormatting event and then using the GridDataRowElement.Background property passed in with the RowFormattingEventArgs.  The data is already loaded into the RadGridView control so the RowFormatting event will not fire.  Even if it did, I think the code would look a lot cleaner if I could just change the color in my method without having to trigger an event.  Is there any way to get the GridDataRowElement for a row without going through the RowFormatting event?

Hi,
I noticed a change between using the RadTreeView Q2 2014 sp1 and Q1 2013 controls: 
I have some data of many-to-many Users *--* Groups. On load, I display the data Users > Groups. But on a button click I change the display to Groups > Users.
I followed the databinding procedures for hierarchical data in http://www.telerik.com/help/winforms/treeview-data-binding-data-binding-basics.html and http://www.telerik.com/help/winforms/treeview-data-binding-data-binding-basics.html, with success.
(I use EF 6, context.Users.Local.ToBindingList() for the datasource, or context.Groups.Local.ToBindingList(), for the other direction).

In the 2013 version of the control, I was able to just reassign the datasource with no problem during runtime. With the newest version of the control I get this error: 
Type: System.NullReferenceException
Target: GetProperties
Exception: Object reference not set to an instance of an object.
Stack Trace:    at Telerik.WinControls.UI.BindingProvider.GetProperties(CurrencyManager cm, String childMember, Int32 level)
   at Telerik.WinControls.UI.BindingProvider.GetObjectRelationDescriptor(RelationBinding relation, CurrencyManager cm, Int32 level)
   at Telerik.WinControls.UI.BindingProvider.RegisterObjectRelation()
   at Telerik.WinControls.UI.BindingProvider.Reset()
   at Telerik.WinControls.UI.BindingProvider.root_PropertyChanged(Object sender, PropertyChangedEventArgs e)
   at Telerik.WinControls.UI.RelationBinding.OnPropertyChanged(String propertyName)

   at Telerik.WinControls.UI.BindingProvider.set_DataSource(Object value)
   at Telerik.WinControls.UI.RadTreeView.set_DataSource(Object value)
...

I am able to get around this by setting the source to null first:
    RadTreeView1.DataSource = Nothing
    RadTreeView1.DataSource = context.Groups.Local.ToBindingList()

Is this by design or is there something I am missing here, such as a better way to achieve this behavior?

Thanks,

Hi

Lets say i have an appointment on mon 10-11 and another on tuesday 10-11 and tuesday 11-12

Normally on schedulers if you try to move an appointment say from mon 10-11 to tues 10-11 where the slot is already taken then
a) the move is disallowed as the target slot is occupied
b) the appointment from monday is moved and sits side by side with the the tuesday appointment giving concurrent appointments

I want a different logic than this.

If you move an appointment from mon 10-11 to tues 10-11 then the existing tues 10-11 slot gets moved to 11-12 and the tues 11-12 gets moved to tues12-1.
In other words I can move an appointment to an occupied slot and everything else gets shunted down to accomodate it (taking into account weekends etc)

Is this possible?

Also how far in advance can you see with the scheduler? Normally I would only want to see a week or 2 but sometimes I might need to scroll down a whole year.

Thanks in advance for any help you can give me.
This certainly does affect whether I will buy the products

Regards
