BeginEdit() on Cell not working from within CellEndEdit event handler

I am trying to validate values being entered into my grid real-time in the CellEndEdit event handler. If I find that the value entered is not valid, I push a message to the user and want to fire the BeginEdit on that same field, to keep them there until they enter something valid.

I cannot kickoff the BeginEdit method successfully on the cell. Sifting through this forum, I found some "like" problems and tried implementing some suggested techniques, all with no success. Below is some sample code.

                    Private Sub grdMain_CellEndEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles grdMain.CellEndEdit         
                     
                If e.Row.Cells(2).Value.ToString <> "" Then         
                    If e.Row.Cells(2).Value.ToString.ToUpper <> "TRUE" And e.Row.Cells(2).Value.ToString.ToUpper <> "FALSE" Then         
                        e.Row.Cells(2).Selected = True         
                        e.Row.Cells(2).CellElement.IsCurrent = True         
                        e.Row.Cells(2).BeginEdit()         
                    End If         
                End If         
                     
            End Sub         

The BeginEdit does not fire, but the cell is selected in the grid.

Problems with Custom Theme

Hi,

I've tried repeatedly following the tutorial for modifying the theme of the RadDock, but to no avail. I follow the steps, and the "HotPepper" theme never appears as an option for RadDock. I noticed the sample refered to "DockingManager" and not "RadDock" which I think may be part of the problem.

Am I completely missing something?

RecurrenceRule

Hello,

Is there a way to save off the RecurrenceRule and then easily load it back in during a future load?

I save the rule to a string variable in:

void Appointments_CollectionChanged(object sender, Telerik.WinControls.Data.NotifyCollectionChangedEventArgs e)

{

string sRule;

sRule = ev.RecurrenceRule.ToString();

}

When I am manually creating appointments,

Appointment appointment = null;

appointment = new Appointment(start, end, summary, description, location);

How can I insert the saved RecurrenceRule into the appointment?

appointment.RecurrenceRule.Equals(sRule); //does not work

Thanks

Adding a RadButtonElement to a Tab

We've had a request to add a close button to each tab in our MDI docking manager rather than use the TdiCloseButton on the far right of the tabstrip. This is similar to Internet Explorer and Firefox's tabbed interface. This is on Q2 2008 SP1.

I've been able to get 99% of the way there but have one nagging little issue I hope you can help with. Whenever I am creating a new MDI child, I am creating a new RadButtonElement via:

private

static Telerik.WinControls.UI.RadButtonElement NewButton()

{

Telerik.WinControls.UI.

RadButtonElement ret = new Telerik.WinControls.UI.RadButtonElement();

(ret.Children[

0] as Telerik.WinControls.Primitives.FillPrimitive).BackColor = System.Drawing.Color.Transparent;

(ret.Children[

0] as Telerik.WinControls.Primitives.FillPrimitive).BackColor2 = System.Drawing.Color.Transparent;

(ret.Children[

0] as Telerik.WinControls.Primitives.FillPrimitive).BackColor3 = System.Drawing.Color.Transparent;

(ret.Children[

2] as Telerik.WinControls.Primitives.BorderPrimitive).Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

ret.MaxSize =

new System.Drawing.Size(16,16);

ret.Text =

"X";

ret.ForeColor = System.Drawing.

Color.Red;

ret.DisplayStyle = Telerik.WinControls.

DisplayStyle.Text;

ret.Alignment = System.Drawing.

ContentAlignment.MiddleRight;

return ret;

}

Then, I add a click handler and increase the ImageTextLayoutPanel's margin to make room for my button and finally add the buttonElement to the children:

Telerik.WinControls.UI.

TabItem tab = pane.DockableTab as Telerik.WinControls.UI.TabItem;

Telerik.WinControls.Layouts.

ImageAndTextLayoutPanel layout = tab.Children[2] as Telerik.WinControls.Layouts.ImageAndTextLayoutPanel;

layout.Margin =

new Padding(0, 0, 20, 0);

Telerik.WinControls.UI.

RadButtonElement button = NewButton();

button.Tag = pane;

button.Click +=

new EventHandler(tab_Close);

button.MouseEnter +=

new EventHandler(closeButton_MouseEnter);

button.MouseLeave +=

new EventHandler(closeButton_MouseLeave);

tab.Children.Add(button);

What I am seeing whenever I add the button element to the tab is the border on the left of the tab is not painted. I've played around with a lot of margin/padding and layout settings but can't seem to get the border to show up correctly. Any suggestions?

Thanks in advance!
