I am attempting to use the CellValidating event. I am encountering two problems. First e.RowIndex is coming back as a -1 on the a new first row. The row has been added using data binding. Question, how can I find what row I am working with. Second, I attempt to update the value (e.Row.Cells(1).value = "99213" in a cell to the default, and the data does not show in e.Value.

Respectfully,
Dave

Is it possible to have a grid as shown in the attachment?

Hi,

I need to have a grid which can simulate the pivoting behavior of a pivot grid. I know Telerik does not have a pivot grid in Winforms, but would like to know if such a thing can be implemented somehow.

In the snapshot attached, pivoting has been done on 2 columns "Designation" and "Age". The remaining columns can either show the count of values or the sum of values.

Hoping for your help,

Thanks and regards,

Nihar.

[Solved] TimeZoneInfo class information required

Hi there,

I have been looking at the RadScheduler for WinForms (Q3 2010), and noticed that there is a TimeZoneInfo class inside Telerik.WinControls.UI.

Using this class it appears I can convert between Time Zones used in the .NET Framework, which is very helpful.

However, the target framework for my project is .NET 2.0 - which normally does not have this functionality (Microsoft only introduced the ability to convert between time zones in the TimeZoneInfo class of .NET 3.5).

So, have Telerik completely re-implemented the TimeZoneInfo class of .NET 3.5 so it can be used in .NET 2.0?

Is this class as accurate as the one in .NET 3.5? I would just like a bit more information about it.

Regards,
Eddie

Shortcuts problem inconsistent behaviour

Hello guys,

I am having a problem with the shortcut control. I want to assign a shortcut key for a radbutton within a radform

so i added a radbutton and a shortcut control in the radform.

In the shortcut control i add input bindings for the radbutton

- Chord == CTRL+N

- Command == ActionCommand

- Context == radbutton1

so its suppose to fire the click event for the radbutton. but sadly im not getting any response.

So i tried another control which is the radtextbox doing all the same procedure as i did for the radbutton. the only difference is the

input binding command == FocusCommand. Surprisingly when i press the shortcut for focus which is (CTRL+F) the textbox was focused successfully?

Am i missing something? What are the possible solutions/workaround for this problem. i attached the source code.

BTW i am using Winforms Q3 2009

Here is my source code

[Solved] Only dock form once

How can I ensure that a Form that has been docked to an MDIForm doesn't get docked a 2nd time? That is, I need a Form to only be visible once. I tried making it a singleton class, but calling the DockControl of the RadDock still added a same form , though one was an empty shell.

Data disappears from unbound grid(first time only) when creating on-demand hierarchical grid/child

Hi,
I have an unbound radgridview and i am trying to add some on-demand (unbound) hierarchical child/grid to it. It seems i have to "load data in the grid" twice to see data. The first time around, i get to see the columns in the master grid but no data. When i "load data in grid" again, i then get the data.

It seems that when the Master Gird is bound and then i create the on-demand child grid, i can see the data. I must be missing some step in the unbound mode and cannot figure out what. Please could you help?

My code (VS2008) is shown below. The issue is i have to click the Button1 twice to get data .
Thanks

Number of child elements in GridExpanderItem

Hey at Telerik

I subscibe to the event below and would like to show in the GridExpanderItem next to the plussign/minussign the number of child elements that exists in child GridViewTemplate.

All i can do is change the SignStyle, but there is no option for adding text.
I have tried to change the Text property, the size property and setting DrawTet to true, but with no luck.

Is there any way to add the text for instance "17" next to the plussign in GridExpanderItem ?

Perhaps it should be a setting that the number of child elements is shown near the expander.

I hope you can help me it's very important that the number is shown here to help people save time from expanding the element.

The tooltip just doesn't get the job done.
