[Solved] Keyboard input change from Year-Month-Day automatically

Hi Support,

We use a RadDateTimePicker with yyyy/MM/dd format.

Is it possible that the user enter only 20120502 and not 2012 + right arrow + 05 + right arrow + 02?

Best regards,
Dagana

How to upgrade from Q3 2009 SP1 to latest controls

We recently purchased the Telerik Premium Collection for .Net and I need to upgrade a winforms app with the newest controls. The old controls were just trail controls. I don't want to make any mistakes and cause my app to stop working so I need advice on how to get the latest controls. I did submit a ticket and i'm waiting but I need to start this right away so I figure I would post the question in the forum as well. Should I just install the new controls or uninstall the old controls first? I'm running out of time so any help would be greatly appreciated.

[Solved] Apply shadow to html formatted label

Is it possible to apply a shadow to text that you have adjusted using html. It seems that I can apply a shadow to text that has not been changed via html. But, If I make size, color, etc changes to text in a label, I cannot successfully apply a label. Here is what I have tried, without success.

lblDateTime.Text = "<html>" & Format(CStr(DateTime.Now), "Long Date") & "<br><font=Arial Black><size=34><color=" & darkNight.ToArgb & ">" & Format(CStr(DateTime.Now), "Short time")

Dim primitive As TextPrimitive = DirectCast(Me.lblDateTime.RootElement.Children(0).Children(2).Children(1), TextPrimitive)

primitive.Shadow = New Telerik.WinControls.Paint.ShadowSettings(New Point(2, 2), Color.Red)

Any help would be appreciated.

Load Childs on collapsing Row in RadGridView

Hi

I'm new to the Telerik Libs.
I rewriting a program to use the Telerik Libs.

The Program should show the strucure of a CAD Structure as a "TreeListView". My Problem is that NOT the complete structure is loaded on startup. So it's only the first level loaded. The other data are laoded, when the tree is collapsed.

So I'm using the GridView as a SelfReference to have the Tree View.

The Problem is how can I show the "+" Icon even if I only loaded the first level. On loading the first level I know if there a sub Items or not.
I have tried it with Me.RadGridView1.Rows(rownum).HasChildRows = True but thats readonly.

And the next thing is, how can I react on collapsing the tree, and reload the sub items

Thanks
Br Flo

PS: I'm using VB.net ad VS2010

[Solved] How to change dropdown backcolor?

We have several raddropdown controls on a form, and they are set to use Windows 7 theme.
Some of these need to have a different background color to indicate that they are required.

We have tried
1. setting the BackColor property in the Properties window - does not change the color.
2. setting it in the code (rddVendor.BackColor=color.yellow)....does not change the color.

I'm sure we are missing something rather simple....can anyone point us in the right direction?
Other info....VS 2010, vb.net, framework 4.03xxxx, Telerik Q1 2012 SP1

Thanks.

UPDATE.....using the following lines of code, we can get a fully colored background.....but if there is a way to fully color the background with only one line, that would be preferrable. Since BackColor is a property of the control, I would expect that to do it....

rddVendor.DropDownListElement.TextBox.BackColor = Color.Yellow
rddVendor.DropDownListElement.TextBox.Fill.BackColor = Color.Yello

Slow performance on large db?

Hi,

Using RadScheduler binding via schedulerBindingDataSource with an appointment table of an access.mdb with over 22000 appointments takes an enormous long time. When I filter to just one month in the Select statement of the TableAdapter resulting to about 200 appointments it takes about 4 seconds. If I also use the field Description it takes about 7 secs. Surely I'm doing something wrong. Could you give me some ideas of possible causes of slow performance?

Thank you
Karl

TreeView in Combobox

Hello,
I would like to have a TreeView element as a selection in a combobox.
And this control should be embedded in a RadCommandbar.

Such an example, I've already found at the following link:

"http://www.telerik.com/community/forums/aspnet/combobox/placing-single-treeview-inside-combobox-dropdown.aspx"

Is there such a thing even for c#.net 2010 Windows Form ?
Thanks for any tip
