I load classes in a propertygrid that I do not have direct access to change the ToString() displayed when the grid item is a collection.

The problem I have is when the property item is a collection, the value shows the full namespace but I would like to override the text value to something more user friendly.

Some of those collections have sub items and some use UIType editors.

Is it possible?

I tried everything I could think of from pgrid_ItemFormatting and from pgrid_SelectedObjectChanged

Hi,

I'm having a problem where I have a gridview with a master and child template.  I noticed that the parent row doesn't seem to be changing when I select a child row from a different row unless I select the parent row first.  The parent row will only change when I select the parent row directly.  If I move from one expanded child row to another expanded child row (a different parent record) this will not update any bound textbox controls with the parent row values.  The previous row values remain in the bound textbox controls.

I may be missing something obvious here but I would have thought that selecting childrows in different records should change the underlying parent record.

Thanks for any advice on this.

Hi,

I'm working on gridview and I updated the latest components Telerik. I tested in Winforms application to display hierarchical data. When I was finally able to view the data, I found a bug.

When I select a child row and all child rows that have the same index are selected. But if I select another row (different index) then all the selected rows to store the value of the previous row selected.
Even in your demo in the object-Relational the same problem exists.

I would like to know if there is already a solution to fix this problem or that it will be corrected in a future patch?

Hi, 

When I create and show RadMessageBoxForm from System.Threading.ApartmentState.MTA thread I cannot copy text from it by Ctrl+C key pressing.
I got ThreadStateException:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.

Hello
 I'm creating a winform application. I need to create certain users with different roles. Here are the 3 user groups:

Admin : RW: Scheduler, Overall Planning data, Data Filter, Leaves Tracker, Scrum Meeting Data, Available PDs, Resource E-mailer
           : R: Effort Recorder
Coord : RW: Data Filter, Scrum Meeting Data, Resource E-mailer
           : R: Effort Recorder, Leaves Tracker, Available PDs, Overall Planning Data,
Tester    : RW: Effort Recorder, Data Filter
          : R: Overall Planning Data, Leaves Tracker, Scrum Meeting Data

As stated above, Admin, Coord and Tester are the 3 user groups under which I've create multiple users. RW states Read-Write access to each of the modules mentioned above (such as Scheduler, Data Filter etc. ).  R indicates only the Read access.

How could I achieve this using winforms? Could you please help?

Here's the initial code I've so far!

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Login : Form
    {
        public Login()
        {
            InitializeComponent();
        }

        private void button4_Click(object sender, EventArgs e)
        {
            Indexer ins = new Indexer();
            ins.MdiParent = this.MdiParent;
            this.Hide();
            ins.ShowDialog();
        }
    }
}

Also, I've attached the design of Indexer which would be the next screens once a user logs in.

Hey all,

So here is my situation:

I have a column that is of type double. If I "accidentally" enter in characters into the filter, I get an exception thrown that says: "FilterExpressionException" unhandled.

Where do I handle this?

Thanks,

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?

Regards
