Remove Blank selection from radcombobox in Edit mode

[David]

I have added some custom fields and bound them to  datasources.

<AdvancedForm Modal="true" Width="400" MaximumHeight="400" />

<ResourceTypes>

<telerik:ResourceType KeyField="AccountNumber" Name="AccountNumber" TextField="AccountName" ForeignKeyField="AccountNumber"

DataSourceID="sdsAccounts" />

<telerik:ResourceType KeyField="ContactNumber" Name="ContactNumber" TextField="ContactName" ForeignKeyField="ContactNumber"

DataSourceID="sdsContacts" />

<telerik:ResourceType KeyField="TaskType" Name="Type" TextField="TaskType" ForeignKeyField="TaskType"

DataSourceID="sdsTaskTypes" />

<telerik:ResourceType KeyField="TaskAction" Name="Action" TextField="TaskAction" ForeignKeyField="TaskAction"

DataSourceID="sdsTaskActions" />

<telerik:ResourceType KeyField="RepNumber" Name="For" TextField="RepName" ForeignKeyField="For"

DataSourceID="sdsReps" />

<telerik:ResourceType KeyField="RepNumber" Name="By" TextField="RepName" ForeignKeyField="By"

DataSourceID="sdsReps" />

<telerik:ResourceType KeyField="PriorityText" Name="Priority" TextField="PriorityText" ForeignKeyField="PriorityText"

DataSourceID="sdsPriority" />

</ResourceTypes>

This is working but when the form loads each datasource has a blank value by default.  This blank value will mess up my SQL.
They are integer fields ich would need a value of   zero

I just want to get rid of the blank so only items in the datasource can be selected.

So i added:

    Protected Sub RadScheduler1_FormCreated(ByVal sender As Object, ByVal e As SchedulerFormCreatedEventArgs)


        If e.Container.Mode = SchedulerFormMode.AdvancedEdit Then
            Dim ddlContactNumber As RadComboBox = DirectCast(e.Container.FindControl("ContactNumber"), RadComboBox)
            ddlContactNumber.Items.Remove(0)


            Dim ddlAccountnumber As RadComboBox = DirectCast(e.Container.FindControl("Accountnumber"), RadComboBox)
            ddlAccountnumber.Items.Remove(0)


        End If
    End Sub

This tells me that it can not find the control by those names.  Am i referencing the names wrong ?


I can cause problems on your sample page as well.

If I edit one of the items and choose "" blank for the Calendar - that item goes into oblivion.

To access the drop-down controls, you need to prefix them with "Res", so for your first one it would be ResContactNumber.

I just want to note, from my experience, even though you remove the first item from the list it will still return a null value for the first item for some odd reason, a bug most likely where it ignores the first item in the drop-down by default.

I hope that helps.
