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 :)

[Solved] Date Format in DetailView

Hi,

I need help with one problem. I got databound ListView on windows form.
One of the columns in bound data is of DateTime type.
How do I display it in format dd/MM/yyyy (without time).
I can return date from database as already formated string but then sorting on this column
works on string value not DateTime.
I can't find way around it. Any help would be greatly appreciated.

Thanks
Chris

Populate GridViewComboBox values from separate database table

Two tables in my database are: Regions and Carriers.
In the Carriers table, there is a field called "Regions".

That 'regions' field will be a GridViewComboBox that should get it's values from a "name" field in the Carriers table.

How would I do this?

Only allowing tabbed documents to be dragged within the tabstrip has cursor issues

If I take a tab strip (like the one in Examples/TabbedDocument) and add the following code in order to only allow dragging the documents within the tab strip they are a part of:

radDock1.GetService<DragDropService>().Starting += (sender, args) =>

{

if ((sender as DragDropService).DragDropContext == DragDropContext.DocumentWindow)

{

args.Cancel = true;

}

};

Then when dragging the cursor does weird things. If I start dragging, it shows the red circle (because I can't drop the document on itself). And if the cursor stays within the tab strip, everything is fine. But if I drag down so I'm hovering over one of the documents themselves, the cursor reverts to a simple pointer, even though I'm still dragging. Ideally, it would remain as a red circle, or if I had first hovered over a different tab, changing the cursor to the valid drop cursor, it should switch back to a red circle.

If I then return to the document tab strip (still dragging), the cursor will come back when I hover over the original document tab being dragged, but not any of the others.
