Hello,

I am working on a custom datagrid for my application and I want to have a custom column where the cell has a Textbox and a small button. When the user clicks the button a small screen must be shown where the user can enter some values. The total of the inputting values need to be displayed back in the gridview.
I am looking at implementing this, but have a hard time doing. I like to have the same style for the button and the subscreen as the datepicker/Calculatorpicker.
The content of the dropdown screen need to be replacable by other content using a usercontrol.

Whats the best way to implement this, should I create a custom control for this? And then create a custom column according to the approach below?

Or is there a better way to implement this?

Thank in advance.

I have used the wizard events to control my wizard navigation but once I cancel the navigation for one step using e.Cancel, The SelectionChanging/ SelectionChanged events doesn't  get fired. 

I was using the UI for WPF Q1 2015 and now updated to UI for WPF Q2 2015 but still the same problem exists.

check this code sample

using System.Windows;
using Telerik.Windows.Data;
using Telerik.Windows.Controls;

namespace WizardNavigation
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        private ObservableItemCollection<WizardPage> collection;
        private int cancelCounter = 1;
        public MainWindow()
        {
            InitializeComponent();

            collection = new ObservableItemCollection<WizardPage>();

            var firstPage = new WizardPage {Content = "My First Page Content"};

            var secondPage = new WizardPage {Content = "My Second Page Content"};

            var thirdPage = new WizardPage {Content = "My Third Page Content"};

            var fourthPage = new WizardPage {Content = "My Fourth Page Content"};

            myWizard.WizardPages.Add(firstPage);
            myWizard.WizardPages.Add(secondPage);
            myWizard.WizardPages.Add(thirdPage);
            myWizard.WizardPages.Add(fourthPage);

            myWizard.Next += myWizard_Next;
            myWizard.SelectionChanging += myWizard_SelectionChanging;
        }

        void myWizard_SelectionChanging(object sender, SelectedPageChangingEventArgs e)
        {
            if (cancelCounter != 2) return;
            e.Cancel = true;
            MessageBox.Show("Cancelled, Click again to navigate");
        }

        void myWizard_Next(object sender, NavigationButtonsEventArgs e)
        {
            // You will need to click the next twice for to move to step 3.
            // SelectionChanging will not be called on the second click
            //SelectionChanging will be called when moving to forth step.
            cancelCounter++;

            var wizard = sender as RadWizard;
            
            if (wizard.SelectedPage.Content == "My First Page Content")
            {
                e.SelectedPageIndex = 2;
            }
        }
    }
}

Hi,

I am trying to replace TextBox that had CharacterCasing="Upper" with RadMaskedTextInput.

I do not want to have placeholders, so I cannot use Mask="&gt;a10"

Is there any other way to change charaters to upper when typing into RadMaskedTextInput?

Thanks,

Lukasz

Hi,

i love the DataForm Control, but is there a way to create the Fields and Layout in Codebehind? We want to create somethinfg like a Form-Designer,
where the user can ​layout the form himself. First Step is to read from a File which fields, position, length,... and 2 Step is to create the field on the form.

Thanks

Best Regards

 Hi,

I am using a customized control derived from TileListPanel. and I have overriden ArrangeOverride() in this control. I am using this control in two different windows and those two windows are being shown at a time on UI.

I am seeing a crash whose callstack is origination from Mycontrols' ArrangeOverride(). Below is the callstack. could you please help me out in fixing this issue.

Object reference not set to an instance of an object.

Hi,

 Can we have a way to get all the child nodes selected just by selecting a parent node. It is possible through checkbox in treeview. But can we acheive the same through selection?

Thanks,

I have a grid view where in one column I need to have two radio buttons defined (yes and no), but If I try that I get an error about "The property "Visual Tree" can only be set once.".  What I'm wanting is for user to be able to change a selection for that row if he makes a mistake.  I'm rather new at all of this so I might be going about this the wrong way, just using examples I've found and trying to piece together something to work.

Thanks,
