a Store question

[Adam]

Hi All,

How can i bind a Dictionary<int,string> collection to a Store object ?


I try like that :

    <ext:Store ID="stFirms" runat="server" AutoLoad="true">
    <Reader>
        <ext:JsonReader>
            <Fields>
                <ext:RecordField Name="id" Type="Int" />
                <ext:RecordField Name="firm" Type="String" />
            </Fields>
        </ext:JsonReader>
    </Reader>
</ext:Store>

and than at code behind:

this.stFirms.DataSource = SqlLibrary.RegisteredFirms();// it returns a Dictionary<int,string> collection
this.stFirms.DataBind();

I use that Stoe for a ComboBox, it loads number of the collection but nothing seen in ComboBox..
And the here is the combo :

<ext:ComboBox 
ID="cmbFirm"
runat="server" Editable="false"
StoreID="stFirms"
FieldLabel="Firm" 
DisplayField="firm"
ValueField="id"
Mode="Local"
ForceSelection="true"
TriggerAction="All"
EmptyText="Choose your firm..."
Width="250">
</ext:ComboBox>

Please check the screen capture for the comboBox..


Thanks..

Have you tried a List of Dictionaries? The dictionary key needs to match the RecordField names... So you would need to return a collection of dictionary<string, string>

Edit: Found out that Coolite (v0.82) does not support binding to a dictionary. You can use the other solution provided at this link:

You would have to specify each fields here.
