Is it possible to open a windows form in an already existing tab? I have predefined tabs in a DocumentTabStip and I want to open a windows form inside of the tab when the tab is selected.

Doing the following will fill the existing tab and create a new blank tab, but I just want to fill the existing tab. I'm sure I'm missing something simple here, but have been struggling for some time. If I eliminate the second line, I get an error.

Dim myForm As New Form1()

Me.DocumentWindow1.DockManager.DockControl(myForm, DocumentWindow1, DockPosition.Fill)

DocumentWindow1.Controls.Add(myForm)

Dock

Change theme in your Winforms Demo

Hi,

I recently installed RadControls for WinForms, Q2 2013 SP1, 13.2.725.0. When I ran the demo to see what was new, the demos all follow the Metro theme. In some past demos, there was a run-time link or control to re-style the demo to use another theme, but I did not see one is this demo. Hopefully it's there and I just missed it.

Frankly I'm not a fan of Metro's blocky, crayon-like primary-colored, squared-off appearance.

Is there any way to change the theme during the demo's run? Or would i have to go change the Demo's source code and rebuild it to do that?

Thanks!
-Bob

GridTimePickerEditor popup clock size

Hi!

I would like to resize my gridtimepicker clock. Main issue is that by default its size hides minutes to choose. I have to resize the clock manually every time to show these options which is irritating. Default view in attachment. How can I solve this problem?

And in addition. How to change color of the hand of the clock? Eg. in Style Builder?

Thanks in advance,
Szymon.

RadAutoCompleteBox IE10 Entry Auto Populated

I am employing many client-side events to show/hide two different AutoCompleteBoxes (RACB) based on certain conditions. I also target the entry added event to display some textboxes on the fly. Mostly everything is working well, however, IE10 is presenting some issues. Upon typing in a letter on the initial load of the control, the next matching record is automatically input into the RACB without actually selecting anything. Once it is removed, the RACB works as designed. It is only on the initial load of the control.

Removing Row and setting previous row as active.

What is the proper way to remove a row and set the previous row as active(if # of rows > 0) on a sorted and/or filtered and/or grouped radGridView?
I populate my radGridView manually with a stored procedure.
The first column in the rGV is a button column when the user presses the button the row should be removed and the previous row set as active/current.
I had this working perfectly when using the DataGridView included with VS2012 but now I'm getting an IndexOutOfRangeException thrown.

Private Sub DataGridView4_CellContentClick(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles DataGridView4.CellClick

If e.ColumnIndex = 0 Then

intDataGridSelectedIndexRenewalC = DataGridView4.CurrentRow.Index

If sps_EIPHasBeenBilled(DataGridView4.CurrentRow.Cells("Policy_no").Value.ToString) Then

RenewalsCommercialMarkComplete()

Else

MsgBox("Unable to Mark This Policy as Complete! " & DataGridView4.CurrentRow.Cells("Policy_no").Value.ToString & " Has Not been Billed Yet.", vbOKOnly)

End If

End Sub

Private Sub RenewalsCommercialMarkComplete()

Dim UpdateStatus As Boolean

Dim SQLQuery As String = "exec " & strDefaultDatabase & ".dbo.spu_EIPRenewalMarkCompleteByRenewalID '" & DataGridView4.CurrentRow.Cells("RenewalsID").Value & "', '" & strLoggedInUserFullName & "'"

If MsgBox("Do you wish to mark this record: " & DataGridView4.CurrentRow.Cells("Customer").Value.ToString & ": " & DataGridView4.CurrentRow.Cells("Policy_no").Value.ToString & " as complete?", vbYesNo + vbQuestion, "Renewal Mark Complete") = vbYes Then

UpdateStatus = WriteSQL_Data(SQLQuery)

If UpdateStatus Then

MsgBox("Record: " & DataGridView4.CurrentRow.Cells("Policy_no").Value.ToString & " Marked As Complete!", MsgBoxStyle.OkOnly)

DataGridView4.ChildRows(intDataGridSelectedIndexRenewalC).Delete()

If (intDataGridSelectedIndexRenewalC - 1) > 0 Then

DataGridView4.ChildRows(intDataGridSelectedIndexRenewalC - 1).IsSelected = True

DataGridView4.ChildRows(intDataGridSelectedIndexRenewalC - 1).IsCurrent = True

End If

Else

MsgBox("Unable to Connect to Database Please see your System Administrator with Error: Summary - ButtonOk_Click: ", vbOK)

End If

Else

MsgBox("The Operation was Cancelled", vbOKOnly)

End If

End Sub

Formatting numeric input

I have a problem with formatting numbers with Telerik controls (version Q3 2012).

Requirements are
- formatting similar to ###,###,##0.00## (limiting number of decimals and also number of digits on the left of decimal point) must be supported.
- formatting mask must be invisible so with mask ###,###,##0.00## text should be only 0.00 and not ___,___,__0.00__.

I have tried to implement this scenario with MaskedEditBox and Textbox but
- in MaskedEditBox i could not hide the mask
- TextBox does not have any formatting options

Is such scenario supported with Telerik controls?

[Solved] Update SelectedNode.DataBoundItem

Hi,

i am trying to build an editable TreeView:

if selectedNade change the current selected value goes to a radtextbox:

private void radTreeView1_SelectedNodeChanged(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)

{

TestItem item = radTreeView1.SelectedNode.DataBoundItem as TestItem;

if (item != null)

{

radTextBox1.Text = item.Name;

radTextBox1.Enabled = true;

}

on KeyUp Event i store the value back:

private void radTextBox1_KeyUp(object sender, KeyEventArgs e)

{

if (radTreeView1.SelectedNode != null)

{

TestItem item = radTreeView1.SelectedNode.DataBoundItem as TestItem;

if (item != null)

{

item.Name = radTextBox1.Text;

}

this doesn't work immediately, but if i click on another node then the last node updates correctly. i tried refresh(), update() and implementing INotifyPropertyChanged, but nothing worked

is live updateing possible?

greetings

Auto Tooltips on DropDownButton

I noticed that even though you set the Auto tooltips to True on the RadDropDownButton it has no effect - no tooltip gets displayed - and yes the Text value is set :)
