Set value to RadDropdownList

Hi Team,
I am new to winform development.
I have bound the RadDropdownList with values from database with DisplayMember and ValueMember properties set properly.
I can see the items in dropdown with no problem.
But when I want to assign the value to RadDropdownList, it sets always to 0 (zero).

Please take a look at my code to bind dropdown :

public void FillInvoiceTypeCombo(int EventTypeID)

{

object businessObject = null;

if (EventTypeID == GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_AP_INVOICE)

businessObject = VoucherDocumentTypeNameValue.GetVoucherTypeNameValue(GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_AP_INVOICE);

else

businessObject = VoucherDocumentTypeNameValue.GetVoucherTypeNameValue(GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_PO_WO_SERVICING);

cmbInvoiceType.DataSource = (VoucherDocumentTypeNameValue)businessObject;

cmbInvoiceType.DisplayMember = "Value";

cmbInvoiceType.ValueMember = "Key";

}

And in another method, I am setting the value of dropdown :

pub void SetControls()

{

// Fill DataSet ds with values from db

FillInvoiceTypeCombo(int.Parse(ds.Tables[0].Rows[0]["AccountJournalEventTypeID"].ToString()));

cmbInvoiceType.SelectedValue = int.Parse(ds.Tables[0].Rows[0]["InvoiceTypeID"].ToString());

}

But every time I get SelectedValue as 0 (zero).

Can you please tell me how can I set the value of the RadDropdownList?

Exceptions in a recurrence rule

I was wondering how exactly exceptions are stored. In the master event's recurrence rule?

For example, if I had deleted an occurrence of a recurring appointment, how would that be stored in a database? Maybe something like DELETEDDATES=ddMMyyyy in the recurrence rule?

Thanks!

Why CurrentRowChanged fires twice?

Hi everybody.

I have a problem with CurrentRowChanged event of GridView. My problem is next.

At form's load event I do this: (rgvClientes is the GridView)

this.rgvClientes.CurrentRow = null;
this.rgvClientes.CurrentRowChanged += new CurrentRowChangedEventHandler(this.rgvClientes_CurrentRowChanged);

Can't Sort Days Order of Appoinments in Monthview

Hello,

I use RadScheduler in my project and my appointments have custom colors, icons etc.

I add appointments to RadScheduler manually in the following way:

foreach (var app in appointments)

radScheduler1.Appointments.Add(app);

I have a problem with RadScheduler MonthView. I want to add appointments to MonthView and I want them to be shown sorted by time (IEvent.Start.TimeOfDay), so if app1.Start.TimeOfDay > app2.Start.TimeOfDay and app1.Start.Date == app2.Start.Date then app1 should appear under app2.

I tried to solve this problem by ordering my appointments collection:

var appointments = src.OrderBy(a => a.Start.TimeOfDay);

foreach (var app in appointments)

radScheduler1.Appointments.Add(app);

But this did not help, so is there a way to solve this problem? Actually I need a way for sorting appointments by time in MonthView.

I am sending you an image of the MonthView, where you can see that appointments are ordered in an inccorrect way. Take a look at Dec 20 and you will see the appointment, that appears at the bottom has its Start.TimeOfDay 09:15, so it should appear as the second starting from the top. Why does it behave in such a strange way?

Thank you for your support.

Expression Based Conditional Formatting on Child Rows

Hi,

I have conditional formatting rules on a parent grid that are defined as expression types

New ExpressionFormattingObject ("COL1",Expression:="COL2 = 1", etc.)

The compare data is in a different column than the formatting. This works OK for the Grid.MasterTemplate.Columns.

I also have identical rules defined for Grid.MasterTemplate.Templates(0).Columns, however the styling does not get applied for these rows on the child grid. If I change the child rules to be ConditionalFormattingObject type as:

New ConditionalFormattingObject ("COL1", Equals, Value:="1", etc.)

the styles are applied correctly. I can't do this though as the data item is in a different column than the formatting. (test against COL1, style COL2)

Is there something I need to do to get the expression rules to format correctly?

Many thanks,

Mark.
