[CLOSED] Combobox with autoload migration from 1.0 to 2.0

[blueworld]

Hello,

I have a 1.0 implementation of a ComboBox that uses an autoload-store

store:

    <ext:Store ID="ReportNameStore" runat="server" AutoLoad="true">
        <Proxy>
            <ext:PageProxy />
        </Proxy>
            <Model>
                <ext:Model runat="server">
                <Fields>
                    <ext:ModelField Name="Name" />
                </Fields>
                </ext:Model>
            </Model>
    </ext:Store>

Combobox:

                    <ext:ComboBox ID="ReportName" runat="server" Editable="true" TypeAhead="true" QueryMode="Local"
                        StoreID="ReportNameStore" TriggerAction="All" SelectOnFocus="true" DisplayField="Name"
                        AllowBlank="true" ValueField="Name" EmptyText="Bericht" AnchorHorizontal="100%"
                        FieldLabel="Bericht">
                        <Triggers>
                            <ext:FieldTrigger Icon="Clear" HideTrigger="true" />
                        </Triggers>
                        <Listeners>
                            <Select Handler="this.getTrigger[0].show();" />
                            <BeforeQuery Handler="this.getTrigger[0][ this.getRawValue().toString().length == 0 ? 'hide' : 'show']();" />
                            <TriggerClick Handler="if (index == 0) { this.clearValue(); this.getTrigger[0].hide(); }" />
                        </Listeners>

Serverside signature:

Protected Sub ReportNameStore_RefreshData(ByVal sender As Object, ByVal e As Ext.Net.StoreReadDataEventArgs) Handles ReportNameStore.ReadData
 
        * Query * ....
        Dim store As Store = sender
        store.DataSource = queryResult
        store.DataBind()
    End Sub

Well, this combobox does not get filled, and if I try to open the combobox the browser debugger tells me

Uncaught TypeError: Cannot call method 'hide' of undefined

Hi @blueworld,

Well, this combobox does not get filled, and if I try to open the combobox the browser debugger tells me

Please use

getTrigger(0)

instead of

getTrigger[0]

I.e. round brackets instead of square ones.

As it is in this example.
https://examples2.ext.net/#/Form/Com...riggerButtons/

I think the ComboBox should be populated well. Sure, if the "queryResult" is correct.

By the way, AutoLoad is true by default.

Hi Daniiil,

thank you, this fixed the javascript exception but the combobox is still empty. QueryResult delievers 5 objects and the readdata function gets executed if I reload the page so this cant be the problem.

The response after the page has loaded is:

{serviceResponse:{success:true,data:{data:[], total: 0}}}

What is the queryResult?

[blueworld]

What is the queryResult?

    Private Class SingleName
        Private _name As String

        Public Sub New(ByVal name As String)
            _name = name
        End Sub

        Public Property Name() As String
            Get
                Return _name
            End Get
            Set(ByVal value As String)
                _name = value
            End Set
        End Property
    End Class

    Protected Sub ReportNameStore_RefreshData(ByVal sender As Object, ByVal e As Ext.Net.StoreReadDataEventArgs) Handles ReportNameStore.ReadData

        Dim reportNames As ArrayList = **NhibernateQuery**

        Dim l As New Generic.List(Of SingleName)
        For Each s As String In reportNames
            l.Add(New SingleName(s))
        Next

        Dim store As Store = sender
        Me.ReportNameStore.DataSource = l
        Me.ReportNameStore.DataBind()
    End Sub

Is PageProxy correct inside the store? In 1.0 the handler has been OnRefreshData, I have changed this to ReadData, is this correct?

Is PageProxy correct inside the store? In 1.0 the handler has been OnRefreshData, I have changed this to ReadData, is this correct?

Yes, the both statements are correct.

I checked your code removing this

 Dim reportNames As ArrayList = **NhibernateQuery**

and populating the ArrayList with just Guids. It appears to be working well.

Please double ensure an object that you apply for DataSource is a collection of objects with the Name property (according the Store Model).

If the issue persists, please provide a full test case that we could run without any changes from our side.

By the way, do you use the latest sources for SVN?

Hi Daniil,

I have just updated to 2.1 and it is working now. Thank you. This can be closed.
