Hello,
in a grid, I want to show a generic list of objects (type: Cars). No problem. One of the columns should be a ComboBox. In the combobox  the selection should be based on a different class (type: Country). The name of country should be displayed in the grid. In both classes, there is a property ID of type GUID. The ID will be created automatically and have no setter.

using System;

using Telerik.WinControls.UI;

using System.Linq;

 

namespace Grid_Test

{

    public partial class frmMitarbeiterlister : Telerik.WinControls.UI.RadRibbonForm

    {

        private TestData.Task taskNewBefore = null;

        private TestData.Task taskNewAfter = null;

 

        public frmMitarbeiterlister()

        {

            InitializeComponent();

            

        }

 

 

        private void GetTestData()

        {

            TestData.TestDataGenerator.GenerateTestData(1000);

            gridMitarbeiterListe.DataSource = TestData.DataAccessLayer.EmployeeList;

            gridMitarbeiterListe.BestFitColumns();

        }

        private void btnTestdatenErstellen_Click(object sender, EventArgs e)

        {

            GetTestData();

        }

 

        private void frmMitarbeiterlister_Load(object sender, EventArgs e)

        {  

            GetTestData();

            GetComboBox();

             

            

        }

 

        private void GetComboBox()

        {

            GridViewComboBoxColumn cbTask = new GridViewComboBoxColumn();

            cbTask.UniqueName = "TaskNew";

            cbTask.HeaderText = "New Task";

            cbTask.DataSource = TestData.DataAccessLayer.TaskCatalog;

            cbTask.ValueMember = "ID";

            cbTask.DisplayMember = "Description";

            cbTask.FieldName = "TaskNew.ID"; // Name in the employee-class

             

            gridMitarbeiterListe.MasterTemplate.Columns.Add(cbTask);

 

            // problem: After leaving the row the new value disapear.

        }

    }

}

Here is my class model

using System;

using System.Collections.Generic;

using System.Linq;

 

 

namespace Grid_Test.TestData

{

    internal static class DataAccessLayer

    {

        internal static  List<Employee> employeeList = new List<Employee>();

        internal static List<Task> taskCatalog = new List<Task>();

 

        public static List<Employee> EmployeeList

        {

            get {

                if (employeeList == null) { employeeList = new List<Employee>(); }

                return employeeList;

            }

        }

 

        public static List<Task> TaskCatalog

        {

            get

            {

                if (taskCatalog == null)

                { taskCatalog = new List<Task>(); }

                return taskCatalog;

            }

        }

    }

}

internal class Employee

    {

        internal Employee() { }

 

        private Guid id = Guid.NewGuid();

        private string firstname;

        private string lastname;

        private DateTime birthDay;

        private Task taskOld;

        private Task taskNew;

 

        public Guid ID { get { return id; } }

        public string Firstname { get { return firstname; } set { firstname = value; } }

        public string Lastname { get { return lastname; } set { lastname = value; } }

        public DateTime BirthDay { get { return birthDay; } set { birthDay = value; } }

        public Task TaskOld { get { return taskOld; } set { taskOld = value; } }

        public Task TaskNew { get { return taskNew; } set { taskNew = value; } }

 

 

 

    }

internal class Task

    {

        internal Task() { }

 

        private Guid id = Guid.NewGuid();

        private string description;

 

        public Guid ID { get { return id; } }

        public string Description { get { return description; } set { description = value; } }

 

        public override string ToString()

        {

            return Description;

        }

 

    }

I have found no example for this purpose. For help, I would be grateful.

Hi
I have just upgraded from 2011.2.11.0712 to Q1 2013.  Then my application breaks.  When one of the form loads, an error message popped up saying "Arrange with infinity or NaN size (parent: Telerik.WinControls.UI.RadPageViewStackElement, this: Telerik.WinControls.UI.RadPageViewStackItem)"

In designer view inside Visual Studio, I got the same error with call stack

at Telerik.WinControls.RadElement.Arrange(RectangleF finalRect)
at Telerik.WinControls.UI.RadPageViewStackElement.ArrangeItems(RectangleF clientRect)

at System.Windows.Forms.Form.ControlCollection.Add(Control value)
at System.Windows.Forms.Design.ControlDesigner.DesignerControlCollection.Add(Control c)

Error list showed the error in designer.cs
Following the line number, the error came from this line

            this.Controls.Add(this.tableLayoutPanel1);

tableLayoutPanel1 is of type System.Windows.Forms.TableLayoutPanel


What does that mean and how to fix?

When I set the ruler background color using the UI Editor, it shows properly in design time but in run time the color is set back the default. I have attached an image showing where I set the color.

Dears,

Despite my investigations on the forums and in my debugger, I didn't find the right way to do what I need.

What I need to do is to change the text present in a GridGroupContentCellElement according to some information present in the column which was selected to create this grouping. Basically cells contain numerical codes as values, but the visual needs to display corresponding labels. This works great with the CellFormatting event but in the ViewCellFormatting, I catch the GridGroupContentCellElement element and then I really wonder how to get back the corresponding column header (at least its Name property).

Do you have any solution for this?

Hello,

Can somebody point out how I might set a custom sort order on a column with following data:-

A/101
B/100
C/102
D/103
E/99
F/75
F/70
F/35

I want to be able to sort on just the numeric part and ignore the first two characters ie "A/"

Anybody got any ideas?

Many thanks

Terry

How can I change font of radgroupboxheader programmatically?

How can I enable AutoEllipsis of grid element, grid text and help area, I tried below (set in my form New() event) but I must be missing a flag somewhere.

Hi Forum,
I've been searching the web and forums for solutions and yet to have found any therefor resulting here, asking you for help.
My Project is on Winforms, C#, DataSetBount RadGridView.
1. I'm looking for a way to change the Text Color of Columns. (Through the code)
2. Export To PDF settings - How do i enable support for Right-To-Left Fonts? (Through the code)
I've managed to find how to change the Font of the GridView, but not the ForeColor nor did i find how to set the RightTOLEFT EXPORTING settings(When On Display - the Font is fine, but when Exported it becomes backward).

Appreciate all the help you care  to provide,
