[Solved] Custom

Hello,

Edit: Sorry for topic name. Can't update it after posting.

I have RadMultiColumnComboBox in GridView.
I replace editor for that column like that:

private void GridView_EditorRequired(object sender, EditorRequiredEventArgs e)

{

if (e.EditorType == typeof(RadMultiColumnComboBoxElement))

{

PersonChecker newEditor = new PersonChecker();

e.Editor = newEditor;

}

and this is my custom class:

public class PersonChecker : BaseInputEditor

{

public override object Value

{

get

{

String all = "";

RadMultiColumnComboBoxElement editor = ((RadMultiColumnComboBoxElement)this.EditorElement);

foreach (GridViewRowInfo gvri in editor.Rows)

{

if (Convert.ToBoolean(gvri.Cells[0].Value) == true)

{

if (all != "")

all += "; ";

all += Convert.ToString(gvri.Cells[1].Value);

}

return all;

}

set

{

Console.WriteLine("to do");

}

protected override RadElement CreateEditorElement()

{

RadMultiColumnComboBoxElement editor = new RadMultiColumnComboBoxElement();

editor.EditorControl.AutoGenerateColumns = false;

editor.Columns.Clear();

GridViewCheckBoxColumn check = new GridViewCheckBoxColumn();

check.HeaderText = "";

check.Name = "Check";

check.MinWidth = 40;

check.MaxWidth = check.MinWidth;

check.ReadOnly = false;

editor.Columns.Add(check);

GridViewTextBoxColumn username = new GridViewTextBoxColumn();

username.HeaderText = "Username";

username.Name = "Username";

username.MinWidth = 200;

editor.Columns.Add(username);

editor.Rows.Clear();

editor.Rows.Add(new Object[] { false, "Person 1" });

editor.Rows.Add(new Object[] { false, "Person 2" });

editor.Rows.Add(new Object[] { false, "Person 3" });

//foreach (Person person in FormMain._persons)

//{

// editor.Rows.Add(

// new Object[] { false, person.SP_Username }

// );

//}

editor.EditorControl.ShowRowHeaderColumn = false;

editor.AutoSizeDropDownToBestFit = true;

editor.PopupClosing -= Editor_PopupClosing;

editor.PopupClosing += Editor_PopupClosing;

editor.EditorControl.CellClick -= EditorControl_CellClick;

editor.EditorControl.CellClick += EditorControl_CellClick;

return editor;

}

private void EditorControl_CellClick(object sender, GridViewCellEventArgs e)

{

if (e.ColumnIndex == 0 && e.RowIndex > -1)

{

e.Row.Cells[0].Value = !Convert.ToBoolean(e.Row.Cells[0].Value);

}

private void Editor_PopupClosing(object sender, RadPopupClosingEventArgs args)

{

if (args.CloseReason == RadPopupCloseReason.Mouse)

{

args.Cancel = true;

}

public override void BeginEdit()

{

base.BeginEdit();

this.EditorElement.Focus();

}

public override bool EndEdit()

{

return base.EndEdit();

}

public override Type DataType

{

get { return typeof(string); }

}

So basically when user edit cell, another grid (custom editor) will show and user can check few person. After editing value in that cell will be set like Person 1; Person 2; Person 3.

This all work just fine but i have problem with text in that cell when user is in edit mode.
After entering edit mode cell text automatically change to "False".
When user check some rows cell text also change according to checked state "False" or "True".

How to avoid that text changing?
I want see my current string (depend what was checked) "Person 1; Person 2; Person 3" in grid cell also in edit mode so will be always updated information.
I another words, how to control text displayed in cell when user is in edit mode?

Move up/down in Outlook view?

Hi,

One of the things I find missing in the Outlook mode of the PageView control is the ability to move a page up or down (i.e., change their order). This is accomplished with an additional menu item called "Navigation Pane Options", and a checked list box with all available pages and up/down buttons.

It seems fairly obvious this functionality isn't included out of the box. Is there a straight-forward way to add it (i.e., add a menu item which could bring up my own dialog for accomplishing this)?

Related to this would be a way to serialize the PageView content and order to XML, but I can see how to do that myself fairly easily with an extension method.

ListView Checkboxes

Hi

I have a ListView in IconViewMode with enabled checkboxes. I need to enable and disable the checkboxes themselves based on some requirments.

I have managed to disable but keep them visible using the VisualItemFormatting method and turning the ToggleElement.Enabled to false

I am having a problem accessing the ToggleElement from anywhere else.
I need to access the checkbox itself the element from SelectedIndexChanged or CurrentItemChanged or any such methods.

Any help please ?

Thank you

multi resource not saving ?

Hi ALL,
   I am in need of some assistance. Software config first..
Win 7 Ult 64, Visual Studio 2010 (VB.NET 2.0, Winforms
Scheduler Q2 2011.2.831 (Latest), VistaDB (Supported
by Telerik ORM) MS SQL 200X Compatible. I have now
"Bound" the Scheduler and I can Create new appoint
ments but save makes the "Appointments" disapear!.
Has anyone ran across this with RadScheduler? (I am
not using ORM) Just the sample .mdb database (used
by telerik example) Converted to VistaDB Format. I
added "User 1", "User2", "User 3", "User 4". to the
resources part of the database and they come up
properly but I Can't figure out the Colors Part Need
Color.Transparent in all 4 spots. I am using the code
"Ivan" Provided and it is in the samples. The "Samples"
do not provide Multi - User Data Binding. It could be a
very simple line of code to solve this problem.
                                                 Thanks in advance!,
                                                                Jeff :)

Dim colors() As Color = {Color.Transparent, Color.Transparent, Color.Transparent, Color.Transparent}

Dim names() As String = {"User 1", "User 2", "User 3", "User 4"}

For i As Integer = 0 To names.Length - 1

Dim resource As New Telerik.WinControls.UI.Resource()

resource.Id = New EventId(i)

resource.Name = names(i)

resource.Color = colors(i)

'resource.Image = Me.imageList1.Images(i)

Me.RadScheduler1.Resources.Add(resource)

Next i

Me.RadScheduler1.GroupType = GroupType.Resource

Me.RadScheduler1.ActiveView.ResourcesPerView = 2

Dropdown lists in Gridview unusable

Hi!
When I have a column as a combo (style: dropdown) then it only works properly when the user selects a value from the list. When an experienced user would type in the value himself, the entered value disappears again, it doesn't matter if you use the TAB or the ENTER.
Is there maybe some kind of property that I need to set to make the control match the entry in the textbox with the values in the list?

By the way: AutoCompleteMode is SuggestAndAppend

Regards,
Martin

Hide non working hours in TimelineView

Hi all,
Is there a way to hide non working hours in TimelineView with Timescales.Hours/HalfHours/Minutes

e.g. collapse Columns before and after the WorkTime-Timespan - thus allowing shorter drag+Drop movements

| Day 1 | Day 2 |
| 08 09 10 11 12 13 14 16 18 20| 08 09 10 11 12 13 14 16 18 20|

Currently I call my own RenderView() method which loops over all visible cells

void ActiveView_PropertyChanged(object sender, PropertyChangedEventArgs e)

{

switch (e.PropertyName)

{

case "StartDate":

It would be more convinient to subscribe to a ElementRender Event and set the background color there - like the one exposed in RadCalendar.

radgridview hierarchy problem

Hi
I ask for help, there is a small problem.

There are two tables: the nomenclature and files.

Nomenclature hierarchy built in RadTreeView.
List of files in RadGridView
When you select a list of files filled in gridview
Doing so:

protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);

            this.nomenclatureTableAdapter.Fill(this.dataSet.nomenclature);
            this.filesTableAdapter.Fill(this.dataSet.files);

            radGridView1.DataSource = this.index3fkBindingSource;

            this.radGridView1.Relations.AddSelfReference(radGridView1.MasterTemplate, "ID", "FID");
        }
The first time he correctly selects and builds a hierarchy.
But when another node, it populates the file list in their previous range, and even without the hierarchy.
SubFiles is not visible and not the list of files.

[Solved] After databind: update current view

Hi,

I have a client server solution. Several clients connect to a single database hosting the scheduler data. When a client changes the data in the database table (adding, removing, changing an appointment) the SQL message broker kicks in and all other clients execute a function to update their scheduler. So far this works like a charm:

''' <summary>

''' Sql Server notifies the scheduler table data is changed!

''' The current scheduler data needs to rebind to reflect the changes...

''' </summary>

''' <param name="sender"></param>

''' <param name="e"></param>

''' <remarks></remarks>

Private Sub AgendaWijziging(sender As Object, e As System.Data.SqlClient.SqlNotificationEventArgs)

If Me.InvokeRequired Then

RadScheduler1.BeginInvoke(New MethodInvoker(AddressOf radScheduler1_rebind))

Else

radScheduler1_rebind()

End If

End Sub

''' <summary>

''' Rebind the scheduler after a database change by another client

''' </summary>

''' <remarks></remarks>

Private Sub radScheduler1_rebind()

Try

Me.Cursor = Cursors.WaitCursor

' attempt to find current first time slot in view (user scrolled to this time slot)

'Dim dayView As SchedulerDayViewGroupedByResourceElement = TryCast(Me.RadScheduler1.SchedulerElement.ViewElement, SchedulerDayViewGroupedByResourceElement)

'Dim singleDayView As SchedulerDayViewElement = Nothing

'Dim resetToTime As DateTime? = Nothing

'Dim firstCell As SchedulerCellElement

'If dayView IsNot Nothing Then

' singleDayView = dayView.GetDayViewElements.FirstOrDefault

' If singleDayView IsNot Nothing Then

' firstCell = singleDayView.DataAreaElement.Table.Children.First

' If firstCell IsNot Nothing Then

'            resetToTime = CType(cell, SchedulerCellElement).Date (date only... no time?)

' End If

'End If

RadScheduler1.DataBind()

' go back to the timeslot the user scrolled to.. (does not work :( resetToTime contains date only )

'If singleDayView IsNot Nothing AndAlso resetToTime IsNot Nothing Then

'    singleDayView.DataAreaElement.Table.ScrollToTime(New TimeSpan(resetToTime.Value.Hour, resetToTime.Value.Minute, resetToTime.Value.Second))

'End If

' re-initialize the sql broker notification

_context.MonitorAgenda()

Catch ex As Exception

Dim currentMethode As MethodBase = MethodBase.GetCurrentMethod

FormHelper.LogError(ex, currentMethode.DeclaringType.ToString, currentMethode.ToString)

Finally

Me.Cursor = Cursors.Arrow

End Try

End Sub

The problem is in the commented code: After the databind is executed, the scheduler view is reset to 00:00 hour. I basically attempt to update the binding without updating the display, so when another workstation adds a appointment on a timeslot in view it just appears in the scheduler the user is looking at or (when in a timeslot out of view) would appear when scrolling. As an added bonus the scheduler contains several resources.

So how can I "detect" the start or end of the top _visible_ timeslot and then use "dv.DataAreaElement.Table.ScrollToTime(TimeSpan.FromHours(firstCell.Hour))" to Update the view after databind?
Or should I approach this differently?

regards,
Raoul
