Using a GridViewCommandColumn to populate other cells

Hi,

I have a gridview with most of the data being read only as it depends on a key column. I'd like to have a GridViewCommandColumn that the user can click on, go to another winform and get back a number of values. These values should then be inserted into the new/edited row.

For example, the button might pop up a product search where I search for a product and when found, return the product name (read only) and product code (editable) to the gridview.

Have you any guidance on this? I tried searching the forums but the search falls over on 'GridViewCommandColumn'.

Edit: I've got the CommandCellClick event working and this works well within the grid if I used the code below, however, it does not work for new rows being added using the 'click here to add a new row' mechanism. The CommandCellClick event still fires and the value assignment does not cause an error, but it does not take effect either.

cell.RowInfo.Cells("MyProductDescription").Value = "abcdef"
cell.Value = Now.ToString() ' This also works, except when the row is a 'new' row added by the UI.

Thanks in advance

Selected row after sorting on initial databind

When I add a sort expression the grid appears to behave as follows during the initial databind:

First row is selected
Grid data is sorted
GridView scrolls it's content down to the row that was selected (which used to be the first row, but after sorting, is now at the bottom of the grid)

The desired behavior is to have the first row selected after sorting (instead of scrolling down to the previously selected row). Does anyone know how to do this?

radComboBox and Null values.

I am displaying list of customers in a radComboBox. its value customerID should be saved into a FK_CustomerID column.
It does this propoerly.

Now when i retrieve the same record , i would like to de-select the customer so that i can set FK_CustomerID to null in database.
but i see that there is no way to deselect the customer to reset FK_CustomerID back to null.

How do i solve this ?

[Solved] gridview validating

Hi !

I have a hierarchical grid view. In the Child grid I press add new row . When I try to validate that row in Validating event I cannot read any of this row fields values. All are null.
Do you have any example regarding new rows validating and how to read valued from the new rows. Because the values are on the screen but cannot be read through the code. I can read the values for already in grid rows but for this new row I can't .
The video example in Support web page with grid validation is working only when edit already in database rows, if you try the same example for a new row is not working !

Regards,
Mihai

[Solved] Keeping the Original Style

When I drag a date time picker onto a form with the normal control background, it looks one way compared to if I drag the control onto panel with a different color background.

Is there a way that I can keep the original style as it looks like on the control background (see attached screenshot)? Or would I have to modify the style somehow to make sure it never changes?

Thanks

[Solved] Errords In Implemening Appointment Factory

Hi Guys

I am working the example on the following link
http://www.telerik.com/help/winforms/binding_to_custom_fields.html

and when I added the following code

    
Imports
 
 Telerik.WinControls.UI.IAppointmentFactory
            
            Public Class CustomAppointmentFactory  
        
             Implements IAppointmentFactory 
        
             #region IAppointmentFactory Members  
        
             Public Function CreateNewAppointment() As IEvent  
        
              Return New AppointmentWithEmail()  
        
             End Function
        
            #End Region  
        
            End Class

On my import statement I am getting the following error
Error 1 'IAppointmentFactory' for the Imports 'Telerik.WinControls.UI.IAppointmentFactory' does not refer to a Namespace, Class, Structure, Enum or Module.

The following error message is on the line Implements IAppointmentFactory
Error 2 Class 'CustomAppointmentFactory' must implement 'Function CreateNewAppointment() As IEvent' for interface 'Telerik.WinControls.UI.IAppointmentFactory'.

And thrid error is String constant expected on the line #region IAppointmentFactory Member

I have referenced the necassary dlls. I am using VS2005.
Thanks
JJ
