Hi There

I'm having some trouble with the order of events for the Cell Format

We do some conditional cell formatting based on values returned from a database, such as what days to block - holidays etc
I managed to get it to work fine the first time round

The issue arises on the following Navigator events

NavigateBackwardsClick
NavigateForwadsClick

as the following event fires before the Navigate event

Scheduler.CellFormating

This seems quite strange, I would have thought that they would be reversed.

How can I call a refresh of the data method and which event should it go in

exceptionTimes = _service.GetSchedulerExceptionTimesByDateRange(RangeStartDate, RangeEndDate)

As putting the values in the Navigate events makes the cellformating event use the previous
range of exception times for the previous date range as defined before the navigate event.

Below is some example code

Private Sub snMain_NavigateBackwardsClick(sender As Object, e As EventArgs) Handles snMainNav.NavigateBackwardsClick
 
    RangeStartDate = rsScheduler.ActiveView.StartDate.AddDays(-1)
    RangeEndDate = rsScheduler.ActiveView.EndDate.AddDays(1)
 
    exceptionTimes = GetSchedulerExceptionTimesByDateRange(, RangeStartDate, RangeEndDate)
    GetAppointmentsByDateRange()
 
 End Sub
 
Private Sub rsScheduler_CellFormatting(sender As Object, e As SchedulerCellEventArgs) Handles rsScheduler.CellFormatting
    ' Other Code 
    For Each Exception In exceptionTimes
        'Block etc
 
    Next
 
End Sub

Grid auto-resize to form resize

I would like for my grid to autosize according to the form size. When the form is resized, I would like the grid to expand. Is there a setting for this anywhere?

Custom style in some columns

Hi,

How to apply (by c# code) custom style (fore color, back color, font etc..) to only specific column, so style will affect all data in that column? I also want change style for individual column header cell and summary cell.
I'm only interested in the change of these properties in some of the columns, not all.

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

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

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
