Helo, I'm with a problem when i try to load a combobox, the datasource of the store is correct,
i saw by watch that the data is on the datasource, but the combo do not show the itens correctly.

Store

<ext:Store ID="strCboTipoCurso" runat="server">
        <Reader>
            <ext:JsonReader ReaderID="tipoCurso">
                <Fields>
                    <ext:RecordField Name="id">
                    </ext:RecordField>
                    <ext:RecordField Name="nome">
                    </ext:RecordField>
                </Fields>
            </ext:JsonReader>
        </Reader>
    </ext:Store>

ASP

<ext:ComboBox ID="cboTipoCurso" StoreID="strCboTipoCurso" LabelCls="lbl100" FieldLabel="Tipo de curso"
Cls="cbo200" runat="server" MinChars="1" MsgTarget="Side" BlankText="Campo obrigatório"
AllowBlank="false">                                
</ext:ComboBox>

C#

        Curso curso = new Curso();
        strCboTipoCurso.DataSource = curso.consultarTipoCursoPorUnidade(cboUnidadesCad.SelectedItem.Value);
        strCboTipoCurso.DataBind();
        cboTipoCurso.DataBind();

Thanks.

Put the properties: ValueField and DisplayField

<ext:ComboBox ID="cboTipoCurso" 
         StoreID="strCboTipoCurso" 
        LabelCls="lbl100" 
      FieldLabel="Tipo de curso"
             Cls="cbo200" 
           runat="server" 
        MinChars="1" 
       MsgTarget="Side" 
       BlankText="Campo obrigatório"
      AllowBlank="false" 

      ValueField="id"  
     DisplayField="nome" >                                
</ext:ComboBox>
