Selection grid

Hello,

Due to some problems implementing radcombobox to select from a list of records, I'm trying to create a radwindow with a radgrid inside to allow the selection of one record from it.

I was reviewing a lot of examples and the example more similar is "Window / Using the URL for Server Arguments". This example only show a radwindow with a grid inside but not return any values to parent form.

For my purposes, just change the parent grid for a data entry form and in a field with a button I want to open a radwindow with the grid and when the user select a record, return the id and description of the record to the parent form to fill the current field.

From this example I'm trying to reduce the overload of getting a lot of data from several tables into the same data entry form.

Could you give provide me with an example of return values selected in a radgrid to a parent form?
Thanks a lot in advanced
Jose

AppointmentCommand is not firing properly

Hi,
Please find below as my requirment.
(Schedular - DayView)

Each appointment is associated with status (like created, confirmed, completed etc) and appointment should have color schema based on appointment status.
For example, all created appointments should disply in Red, confirmed appointments should display in Yellow etc.
Also, buttons should be displayed with each appointments, when user clicks on any button, appointment status should changed accordingly. i.e, when user clicks on Yellow Button, appointment status should be changed to confirmed.

To achieve above requirement, am making use of Appointment Template, AppointmentCreated event, AppointmentCommand events of Schedular control.

Am using AppointmentCreated event for background color logic and AppointmentCommad event for updating appointment status logic.

When I clicks on button, which is in appointment template, order of events which are fired are AppointmentCreated, AppointmentCommand.

Everything working fine so far which satisfies my requirement. But the problem is, some times (randomly), buttons requires multiple clicks to fire “AppointmentCommand” event. In other words, when I click on button, it is only fires “AppointmentCreated” and not firing “AppointmentCommand”.

Any one, could you please help me in this issue. Thanks in advance.

Thanks,

Sumanth

Sorting: NullReferenceException

Hi,

my grid displays - for example - organization units: OrgUnit objects. The OrgUnit class has a property "Manager" which contains an instance of the class "Person". This class has, in turn, a property named "FullName".
I want to display names of managers in one of the grid's columns. I bind this column with: "Manager.FullName". And it works perfectly - event for units with no manager.
Then, I want to sort my grid by this column. I put SortExpression="Manager.FullName". It works - but fails (NullReferenceException) when any of displayed units has no manager.
I understand that "Manager.FullName" can raise this exception when "Manager" is null but when displaying data it doesn't.
Can I solve this problem any way?
The workaround: define a special property "ManagerFullName" (return Manager == null ? "" : Manager.FullName) is not acceptable.

Tomasz

Rad Grid printing losing data

Ok, I am working with a web part that is used in multiple place in our code for reports. The web part has a RadGrid on it. The grid itself is set to take up to 100% of the container it is in. The issue I am having is that for some reason on one of the reports when we print it out or do a print preview, the grid headers and about 10 to 15 rows of data are missing. The first page of the print out has the content above the grid printing and the second page starts between row 11 and 15. Now, when I go into the print preview funtion and change the Zoom percentage to 150% or a custom 200%, I can see more or even all the rows that are missing as well as part of the header rows. The other reports that are using this web part all work fine. The report is also missing about half of a column of data. There is one of the other reports that is missing 1 and a half columns of data, but the the headers and all the data print.

Has anyone else seen an issue like this?
