Gridview template tutorial

Hello

I have a class that holds two other classes Like this

public Class A

{

Some properties From A

some methods From A

}

public Class B

{

some properties from B

Some methods from A

}

public Class C

{

public Aclass a;

public Bclass b;

}

However I need to list a collection of Class c in a list where some columns shouldn't show, some should be readable only, some should have another Columnheader name than class property name. I figure I need to make a template class where I extend a gridview template class, however I am unable to find a tutorial on how to make such a template class

Any Information on this is appreciated.

----
Expected result
I am not exactly looking to change backgroundcolor or play music, but these are some of the things that are possible with a template

public Class Gridview

{

private void someMethod()

{

   gridview.Template=new Templ;

}

private

class templ : Template

{

put this information from these classes into those columns

make some columns do this

make each four row have a button that play a song

make the background appear as something specific depending on teh information it has

}

}

TimePicker in a datetime column

Hi All!

I have a grid, with some DateTime column, but I would like to change the original DateTime picker to Time picker, because in some cases the date part is disinterested, and the user wants to set specific time moments in a user friendly way.

It is possible to do this?

Best regards,
Peter

[Solved] How to add check box to Context Menu

Hello,

I've created a RadContextMenu and wanted to add a few check boxes for user to check and un-check when right click. I see that the RadContextMenu can add combo box, but what about checkbox? After a check box is check. I want it to stay check until the user right click and un-check it. Is this possible?

Thanks in advance for the help.

[Solved] theming buttons in a user control

I am trying to set an entire WinForms app with Desert theme
I have a group of buttons in a user control which is used in two different forms
both forms are RadForms and both are set to Desert as part of the constructor

Public Sub New()

' This call is required by the designer.

InitializeComponent()

Dim myTheme As New DesertTheme()

ThemeResolutionService.ApplicationThemeName = "Desert"

End Sub

one form has ochre buttons with that gradient I like - and the other form has that ugly grey which is Microsoft control
why is this?

I figured out why - after leaving a dent in my desk after trying EVERYTHING I could think of
the user control starts out not Enabled - when it is Enabled it gets the nice gradient

Buttons, RadioButton, CheckBox, etc

Converting code snippet from c# to vb.net

Hi,

can anyone convert this code to vb.net, please?

radscheduler1.AppointmentEditDialogShowing += new EventHandler<Telerik.WinControls.UI.AppointmentEditDialogShowingEventArgs>(radscheduler1_AppointmentEditDialogShowing);

The Telerik converter generates this, but it doesn't work.

radscheduler1.AppointmentEditDialogShowing += New EventHandler(Of Telerik.WinControls.UI.AppointmentEditDialogShowingEventArgs)(radscheduler1_AppointmentEditDialogShowing)

Thanks + greeting

MaskFormat.ExcludePromptAndLiterals

I created a support ticket and asked the following question:

I am binding a RadGridView to a SQL Server table.
The code below returns the following Data Exception Error:
Cannot set column 'SSAN'. The value violates the MaxLength limit of this column.

The SSAN field is a varchar(9). It should store 111223333 and not 111-22-3333. How can I set the column to save the text without the literals?

Dim col As GridViewMaskBoxColumn = New GridViewMaskBoxColumn

With col

.Name = "SSAN2"

.FieldName = "SSAN"

.HeaderText = "SSN"

.MaskType = MaskType.Standard

.Mask = "000-00-0000"

.TextAlignment = ContentAlignment.MiddleCenter

.DataType = GetType(String)

'.FormatString = "{0:000-00-0000}"

End With

RadGridView1.MasterTemplate.Columns.Add(col)

Svett from Telerik answered with the following:

You can achieve that by creating a custom editor:

Public Class CustomMaskedEditor

Inherits RadMaskedEditBoxEditor

Public Overrides Property Value() As Object

Get

Dim value__1 As Object = MyBase.Value

value__1 = Convert.ToString(value__1).Replace("-", String.Empty)

Return value__1

End Get

Set

MyBase.Value = value__1

End Set

End Property

End Class

Then you should use the EditorRequired event of RadGridView to replace the default one:

Private Sub radGridView1_EditorRequired(sender As Object, e As EditorRequiredEventArgs)

If e.EditorType = GetType(RadMaskedEditBoxEditor) Then

e.EditorType = GetType(CustomMaskedEditor)

End If

End Sub

I did not realize that my ticked had been closed because of my delayed response and I asked Svett if the following would not also be a solution:

Imports Telerik.WinControls.UI

Public Class CustomMaskedEditor

Inherits RadMaskedEditBoxEditor

Public Overrides Sub BeginEdit()

MyBase.MaskTextBox.TextMaskFormat = MaskFormat.ExcludePromptAndLiterals

MyBase.BeginEdit()

Me.EditorElement.Focus()

End Sub

End Class

Can anyone tell me if this is not an acceptable way to only have the numbers saved to the database?

button element images not showing in my gridview

Upgraded to Version 2012.2.726.40 today and have been struggling to get my project working again.

One thing I noticed right away is that my command buttonelements in my grid no longer display their images.

here's how I am adding them in code:

private void radGridViewJobs_CellFormatting(object sender, CellFormattingEventArgs e)

{

try

{

foreach (RadElement ele in e.CellElement.Children)

{

if (ele is RadProgressBarElement)

{

e.CellElement.Children.Remove(ele);

break;

}

if (e.CellElement is GridCommandCellElement && !(e.CellElement.RowElement is GridTableHeaderRowElement))

{

GridViewCommandColumn column = (GridViewCommandColumn)e.CellElement.ColumnInfo;

String colname = column.FieldName.ToLower();

if (colname == "stationview")

{

RadButtonElement element = (RadButtonElement)e.CellElement.Children[0];

element.Image = global::PayerConnectClient.Properties.Resources.workstation;

element.DisplayStyle = DisplayStyle.Image;

element.ImageAlignment = ContentAlignment.MiddleCenter;

String myStation = e.CellElement.RowInfo.Cells["workstation"].Value.ToString().Trim();

if (myStation.Length > 0)

{

element.ToolTipText = @"View/Modify " + myStation + " Profile and Current Configuration";

element.Enabled = true;

element.DisplayStyle = DisplayStyle.Image;

element.ShowBorder = true;

}

else

{

element.Enabled = false;

element.DisplayStyle = DisplayStyle.None;

element.ShowBorder = false;

}

if (element.ElementState == ElementState.Constructed)

element.Click += new EventHandler(Workstation_Click);

}

catch (Exception ex)

{

RadMessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, RadMessageIcon.Error);

}

Other than the Telerik update - nothing else has changed.

Any help you could provide would be greatly appreciated. This is extremely urgent as I will be demoing this product early next week.

thanks!

Note: I am using 4 different themes: Office2010Blue, Black and Silver and Windows7. All themes show same behavior.

Docking in a UserControl

So here is our scenario:

We have a main executable (app) with docking enabled. A Left Panel and a Right panel. Each of them can be undocked and pulled out of the application.

The left panel is a no brainer it contains windows controls, etc.

The right panel has a few windows controls, and a user control that we created and also has docking enabled?

So there are a couple questions:

1. Is this scenario able to be accomplished?
2. Can we build a user control that contains docking?
3. If the user control, has a docked panel(s), can we pull those out not only from the user control but also from the main application?

I hope that makes sense. Thank you in advance for any tips, gotchas, etc.
