Hi,

I need to be able to work with Nullable Doubles for these types of editors.  I've migrated from Infragistics to Telerik.  Infragistics has a nice Spin Editor in their masked edit editor which I am missing here. 

However, I am having trouble with Bindings and using nulls.  In my scenario, I have added the masked edit and spinner to a form.I have created the following class to bind to:

class MyClass : INotifyPropertyChanged
{
 private double? _summit; public event PropertyChangedEventHandler PropertyChanged;
 public double? Summit
 {
  get { return _summit; }
  set { _summit = value; OnPropertyChanged("Summit"); }
 } private double? _spinMe;
 public double? SpinMe
 {
  get { return _spinMe; }
  set { _spinMe = value; OnPropertyChanged("SpinMe"); }
 }
 
 protected void OnPropertyChanged(string name)
 {
  if (PropertyChanged != null)
  {
   PropertyChanged(this, new PropertyChangedEventArgs(name));
  }
 }
}

I am declaring a form field as follows:
MyClass myclassinstance = new MyClass();

I am calling the following in form load:
myclassinstance.Summit = 123.987;
myclassinstance.SpinMe = 101.21;
this.radMaskedEditBox1.DataBindings.Add("Value", myclassinstance, "Summit", false, DataSourceUpdateMode.OnValidation);
this.radSpinEditor1.DataBindings.Add("Value", myclassinstance, "SpinMe", false, DataSourceUpdateMode.OnValidation);

I have a button that displays the values when clicked.When the form shows, the masked edit for summit shows 123.987.  The spin editor shows 0.00.
When I click the button, this shows the 2 values as initialized - 123.987 and 101.21.
If I blank the spin then it reverts to 0.00.  Clicking the button shows the value as 101.21.
If I blank the masked edit and click on the button the value is still 123.987.

If I type a value into the spin edit then I need to understand how I can use binding with these nullable doubles correctly.

I can't see any nice Telerik examples of these and thought the community may benefit and I need help ASAP - I thought without opening a support case.  Appologies if I have missed anything.

Thanks

Hi,
I'm trying to handle this event, but I'm getting this error:
"'ContextMenuOpening' is not an event of 'Telerik.WinControls.UI.RadChartView'"
Note: I'm using RadControls for WinForms Q2 2012.

Hi,

To all having a problem with a blank page when you try to load a document to PdfViewer.
After doing a little investigation it appears that the problem may be in the machine that scan documents.
In the company I have two identical machines LaserJet M5035 MFP where users can send a e-mail with scanned document in PDF format.
It turned out that only files sent from the machine with a new firmware 20140503 48.303.1 works.

You can download attached PNG files and rename extension do PDF to view these files.
In the attached file Compare.png you can see the difference when you select the file contents. Invalid file contains additional margin at the top and bottom.
So there is something wrong with the structure of the file created in an earlier version of firmware - 20130510 48.283.4.
I would like to mention that both files can be opened correctly in Adobe Reader.

After upgrading device firmware, machine started to create the correct files.
What is wrong with the file Old firmware.pdf that the Adobe Reader can open it, but Telerik PdfViewer not?

No way to customize AllowEdit = False, in some columns?

When property AllowEdit = True, all columns can be edited. 
As I can choose the columns you wish to edit. 

Thank you

Hi,
I am able to successfully bind hierarchical data with two levels (for example, "Categories\Products"), but I would like to databind 3 different collections of different types, the result being something like:

+Categories
    CategoryA
    CategoryB
+Products
    Product1
    Product2
+Location
    LocationX
    LocationY

where

public IList<Category> Categories { get; set; }
public IList<Product> Products  { get; set; }
public IList<Location> Locations  { get; set; }


Similar to this question: http://www.telerik.com/forums/treeview-binding-to-multiple-object-types-in-mvvm

Aside from 'selecting' each item into a new common type, is there a better way to do this?

Thanks for your input,

hi, is it possible to stack legend in two rows or more, instead of just one in the top of a chart?
Because legend is flowing outside the chart when there are many legend

like so:
Legend1 Legend2 Legend3 Legend4 Legend
Legend5 Legend6 Legend7 Legend8 Legend9

And not like so:
Legend1
Legend2
Legend3
Legend4
Legend5
Legend6
Legend7

Hi
I have a grid with some ReadOnly columns; also in CellFormatting event I set some cells as disabled according to other cells valuse based on business logic.When I use Tab for navigation between columns, it skips ReadOnly columns and set first next editable column as current; but when I use Enter key for navigation, it stops on all columns one by one, ReadOnly or not ReadOnly.
In addition, Tab key stops on disabled cells (without showing focus rectangle) as same  as Enter key; is there any way for correcting Tab key behavior and simulate Enter key behavior as corrected Tab key behavior?

Hi There,
it is the first time I use the visual builder to change a theme. I need some help.
Starting from the theme Visual Studio 20012 Dark, I have changed all settings in a radsplitButton.disabled to be the same of the normal status.
However, when I visualize the theme in the style visualization and even when I try to apply it to a split button in a winform, all my my changes have no effect.


Some help will be appreciated.

Hi there, 

I made a small project where I use a radTextBox, radGridview, etc. I would like to know how to do to generate the installer using InstallShield and work with telerik controls. 

work with VisualStudio 2012 vb.net

I have a RadGridView with GridViewCheckboxColumn.

When  I click on any cell in the grid I catch the CellClick event of the grid and   check/uncheck the checkboxcolumn in the specific current row.

It work fine in all the cells except for click on the checkbox cell that do change the value but  the result doesn’t appear in the checkbox.

 The changes are seen only after I move the cursor.

How it is possible that the value is changed but the checkbox isn’t checked/ unchecked ?

  void RadGridView_CellClick(object sender, GridViewCellEventArgs e)

        {

            if (e.RowIndex > -1)

            {

                if (e.Row.Cells["Sel"] != null)

                {

                    if (e.Row.Cells["Sel"].Value != DBNull.Value)

                        e.Row.Cells["Sel"].Value = !Convert.ToBoolean(e.Row.Cells["Sel"].Value);

                       

                    else

                        e.Row.Cells["Sel"].Value = true;

                       

                }

            }

           

        }
