Hi,

I've just started evaluating the RadControls for use in one of our products, to replace the standard .Net controls we currently use.  I'm attempting to replicate some functionality we have in one of our existing forms.  This takes the form of a general data entry form, where the make-up of the grids are based upon a configuration stored in a database.  As such, each grid is built programmatically and is not bound to any objects or data.

My questions are:

1. Is there a way to show a blank row for data entry as a default, rather than the "Click here to add a new row" option?  Our users' primary input method is keyboard, so I would rather everything was driven from there without any need for using the mouse.
2. When using a GridViewDateTimeColumn, can the time be completely hidden from view?  I wish to show the date only in dd/MM/yyyy format, and I have been changing the Format, FormatString, and DataEditFormatString properties of the column to try to get this in place with no luck.  Either the time is visible when in view mode, or the full (long) format for the date is used when in edit mode.
3. Also date related, most of our users will be in Australia, where the standard date format is dd/MM/yyyy.  However, the datetime control in the grid seems to be limiting what dates can be entered based on the current month.  As an example: I want to enter the date 31/08/2010, but the current month is september, so when I type 31, it first changes the date to 3/09/2010 (as I would expect) then to 01/09/2010 (as September only has 30 days).  I understand this wouldn't be an issue in the US, where the month is usually entered first, but it could cause a major issue for our users.  Is there a way to get round this, either by amending some properties on the object or by intercepting some events of the control and customising the response?
4. What is the best way to determine when a new row is added to the grid?  On the standard control there is a UserAddedRow event.  Is there an equivalent in the RadGridView?
5. Can I specifically focus on a particular cell in a grid?  i.e., is there an equivalent of the DataGridView.CurrentCell property?
6. Can I hide columns from view while still maintaining the values?  I need to be able to specify a default value for some fields that cannot be changed by the user, and previously this was done by setting the column visibility flag to False.  I can't seem to find a similar property on the columns in the RadGridView.
7. Lastly, do you have a guide for people migrating from the standard .Net WinForms controls to the RadControls?  Something that maps the properties and events from one to the other would be a fantastic reference document.

Hi

I want to remove the Minimize and Maximize buttons on a ribbonbar and the normal properties do not seem to work either on the actual form or ribbonbar control.

Any help would be appreciated.

Hi All,

Our application contains a grid that allows grouping and multi select. Upon entering the screen the groups are collapsed. Our client wants to be able to select on or more groups and all it's child records by clicking on the group(s) without expanding them.

I achieved this behaviour via the following event handlers:

The first event is used to change the row color of a group in case one of its child records is selected:

the second event i use to select all child rows in case a group was selected (this currently works only in case of on level of grouping) and i always invalidate all rows to make sure that the formatting event is triggered for all groups (for instance a child row is selected i want the color of the group to change aswell)

The problem however with this approach is that the shift option for multi select is not supported. A user can now select multiple groups with the ctrl button but not with the shift button. Somebody any idea? Other ideas to implement such a behaviour?

Many thanks!

Maarten

Hello all,
Recently for a project i needed to install the Telerik component package because the project which was handed over to me for further development process were heavily based on Telerik components ( such as themes,Gridviews,Buttons ,ComboBoxes,etc) i tried installing RadControls_WinForms_2010_1_10_308_dev that i already had on my Visual Studio 2010Sp1 .
after installing that and running the project for the first time , i noticed an extreme lag in using Visual Studios . even renaming a buttons name would take more than a minutes , let alone navigating through toolbox , dragging new item and start working on them! (another example is when i click on the run project in visual studio , the application takes from say 30 seconds to sometimes 2~5 minutes to execute!!, i get multiple designer time exceptions as well ! which is bad , very bad!)
the lag is so extreme that a process which would take me only 30 minutes in a normal form application , takes more than 3 hours and so on ! which is extremely bad . 
now i want to know if this is normal with teleriks components , since if it is that heavy and resource intensive , we should definitely put it aside and start using sth else . if it is not what would be the cause  ?
(please note that in the current project , there are 17 RadGridViews plus other Teleriks Components such as RadTextBoxes and RadLabels and so on - i said it because i thought it might be better told )
Ok , now what is the problem in case there is a problem ?

Hi, 
I want to restrict access, or be able to remove the edit function to the Textbox in the DateTimePicker.
I tried to hook into the  TextChanging Event of th radDateTimePicker1.DateTimePickerElement.TextBoxElement and set the e.cancel = true. No visible changes was made when trying to edit the text, but it seems like it set some date in behind anyway.

I could do Enabled = false on the TextBoxElement, but then the control seems locked and I want the user to be able to push the dropdown button and select the date from the calendar. 

Is there any good way to restrict this access?

Hi,
i have the following two questions:

1. Is there an option to disable the "snap to grid" behaviour for appointments to show it at the real y-position.
   In the attachement you see an sample of a snapped appointment.
2. How can I cutomize the appearance of an appointment in the view
   For example showing only the begin time, showing an additional picture or text.

Best regards
Friedhelm
