[Solved] A couple of problems with sorting

Hello!

I found a couple of problems with sorting in the latest WinForms RadGridView (2011.1.11.315). I use Visual Studio 2008 with .NET 3.5.

I have created a single form with a RadGridView.

Form1.cs

using System.Collections.Generic;

using System.Windows.Forms;

namespace Test

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

List<DataItem> list = new List<DataItem>();

list.Add(new DataItem() { Name = "Item 1" });

list.Add(new DataItem() { Name = "Item 3" });

list.Add(new DataItem() { Name = "Item 2" });

radGridView1.DataSource = list;

}

public class DataItem

{

public string Name { get; set; }

}

Form1.Designer.cs

namespace Test

{

partial class Form1

{

/// <summary>

/// Required designer variable.

/// </summary>

private System.ComponentModel.IContainer components = null;

/// <summary>

/// Clean up any resources being used.

/// </summary>

/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>

protected override void Dispose(bool disposing)

{

if (disposing && (components != null))

{

components.Dispose();

}

base.Dispose(disposing);

}

#region Windows Form Designer generated code

/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

Telerik.WinControls.UI.GridViewTextBoxColumn gridViewTextBoxColumn1 = new Telerik.WinControls.UI.GridViewTextBoxColumn();

Telerik.WinControls.Data.SortDescriptor sortDescriptor1 = new Telerik.WinControls.Data.SortDescriptor();

this.radGridView1 = new Telerik.WinControls.UI.RadGridView();

((System.ComponentModel.ISupportInitialize)(this.radGridView1)).BeginInit();

((System.ComponentModel.ISupportInitialize)(this.radGridView1.MasterTemplate)).BeginInit();

this.SuspendLayout();

//

// radGridView1

//

this.radGridView1.BackColor = System.Drawing.SystemColors.Control;

this.radGridView1.Cursor = System.Windows.Forms.Cursors.Default;

this.radGridView1.Dock = System.Windows.Forms.DockStyle.Fill;

this.radGridView1.EnableCustomSorting = true;

this.radGridView1.Font = new System.Drawing.Font("Segoe UI", 8.25F);

this.radGridView1.ForeColor = System.Drawing.SystemColors.ControlText;

this.radGridView1.ImeMode = System.Windows.Forms.ImeMode.NoControl;

this.radGridView1.Location = new System.Drawing.Point(0, 0);

//

// radGridView1

//

gridViewTextBoxColumn1.FieldName = "Name";

gridViewTextBoxColumn1.FormatString = "";

gridViewTextBoxColumn1.HeaderText = "Name";

gridViewTextBoxColumn1.Name = "Name";

this.radGridView1.MasterTemplate.Columns.AddRange(new Telerik.WinControls.UI.GridViewDataColumn[] {

gridViewTextBoxColumn1});

sortDescriptor1.PropertyName = "Name";

this.radGridView1.MasterTemplate.SortDescriptors.AddRange(new Telerik.WinControls.Data.SortDescriptor[] {

sortDescriptor1});

this.radGridView1.Name = "radGridView1";

this.radGridView1.RightToLeft = System.Windows.Forms.RightToLeft.No;

this.radGridView1.Size = new System.Drawing.Size(284, 264);

this.radGridView1.TabIndex = 0;

this.radGridView1.Text = "radGridView1";

//

// Form1

//

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

this.ClientSize = new System.Drawing.Size(284, 264);

this.Controls.Add(this.radGridView1);

this.Name = "Form1";

this.Text = "Form1";

((System.ComponentModel.ISupportInitialize)(this.radGridView1.MasterTemplate)).EndInit();

((System.ComponentModel.ISupportInitialize)(this.radGridView1)).EndInit();

this.ResumeLayout(false);

}

#endregion

private Telerik.WinControls.UI.RadGridView radGridView1;

}

The grid sorting is set in the Property Builder. But when line

((System.ComponentModel.ISupportInitialize)(this.radGridView1)).EndInit();

is executed, the SortDescriptors collection is cleared and the grid becomes unsortable. This worked well in v.2010.3.10.1215.

Another problem concerns the custom sorting. I found that the CustomSorting handler is not called if the SortDescriptors collection is empty. I think this is not correct behavior, because the custom sorting logic is coded explitly and it should not depend on the grid sort descriptiors. If we note the first problem listed above, the CustomSorting handler is not called until the SortDescriptors collection is explicitly populated with the application code, or the column header is clicked by user.

Thank you.

Good Evening

I am using the 2010 Q3 controls and i have created some buttons within a Vertical Button Group. However the controls that i have had on there and assigned code to and everything have suddenly vanished and keetp vanishing even when i recreate them however i have to create them with a different name.

They are in the designed code:

Me.btnSetVATFigure = New Telerik.WinControls.UI.RadLabelElement

and

'

'RadRibbonBarButtonGroup4

'

Me.RadRibbonBarButtonGroup4.Items.AddRange(New Telerik.WinControls.RadItem() {Me.RadButtonElement18, Me.btnRemoveProject, Me.RadButtonElement17, Me.btnPricingRemoveProject, Me.btnPricingEditPrices, Me.RadButtonElement20, Me.btnSetVATFigure})

Me.RadRibbonBarButtonGroup4.Name = "RadRibbonBarButtonGroup4"

Me.RadRibbonBarButtonGroup4.Orientation = System.Windows.Forms.Orientation.Vertical

Me.RadRibbonBarButtonGroup4.Text = "RadRibbonBarButtonGroup4"

note end of the first line me.btnSetVATFigure

However as you can see from the attached screen shot the button is not visible on the form.

Can someone please explain this to me as its getting very annoying now as I'm sure you will appreciate.

Thank you in advance

Cues not shown on RadioButtons

Hello,
maybe somone can help me with this little problem.
I have a Groupbox with several RadioButtens in it. Then I added a RadShortCut to the GroupBox and I want the first RadioButton in that GroupBox to be focused.
This works in principle, the RadioButton gets the focus, but the cues are not shown for the focused RadioButton. This is not the expected behaviour, so the user cannot see that he has entered the GroupBox.
Only when using the TAB key to move to the GroupBox the cues are shown. I want to show the cues programmatically. Is there an option to do that?
I used the following code:

Imports Telerik.WinControls
Public Class Test4
     Private Sub Test4_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        ThemeResolutionService.ApplicationThemeName = "Desert"
         RadGroupBox1.HeaderText = "<html><u>R</u>adGroupBox1"
        RadGroupBox1.RootElement.Shortcuts.Add(New RadShortcut(Keys.Alt, Keys.R))
        AddHandler RadGroupBox1.RootElement.Click, AddressOf RadGroupBox1_Click
    End Sub
     Private Sub RadGroupBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadGroupBox1.Click
        RadRadioButton1.Focus()
    End Sub
End Class

Thank you for any hint.
Cheers Roberto
