[infonext]

Hi all,

i need if is possible a sample of CustomAttributeBinding syntax with Razor view.

Thanks.

[Vladimir]

Can you provide more details about what is CustomAttributeBinding?
Where we can read about it?

Thanks

Hi Vladimir,

i tried to convert a piece of webform view to razor view.

  <ext:TreePanel
                          ID="TreePanel1"
                          runat="server"
                          Width="350"
                          Height="450"
                          AutoScroll="true">
                          <Store>
                            <ext:TreeStore ID="TreeStore1" runat="server" DataSourceID="MnuXmlDataSource">
                              <DataBindings>
                                <ext:NodeBinding DataMember="Funzioni" Text="Funzioni" ExpandedField="Expanded">
                                </ext:NodeBinding>
                                <ext:NodeBinding DataMember="Procedura" TextField="Text">
                                </ext:NodeBinding>
                                <ext:NodeBinding DataMember="Raggruppamento" TextField="Text" NodeIDField="NodeID">
                                  <CustomAttributeBindings>
                                    <ext:CustomAttributeBinding AttributeField="Security" />
                                  </CustomAttributeBindings>
                                </ext:NodeBinding>
                                <ext:NodeBinding DataMember="Funzione" TextField="Text" ExpandedField="Expanded" NodeIDField="NodeID">
                                  <CustomAttributeBindings>
                                    <ext:CustomAttributeBinding AttributeField="Security" />
                                  </CustomAttributeBindings>
                                </ext:NodeBinding>
                                <ext:NodeBinding DataMember="Gestione" TextField="Text" ExpandedField="Expanded" NodeIDField="NodeID" LeafField="IsLeaf" HrefField="Href" IconField="Icon">
                                  <CustomAttributeBindings>
                                    <ext:CustomAttributeBinding AttributeField="Security" />
                                    <ext:CustomAttributeBinding AttributeField="CodiceProcedura" />
                                  </CustomAttributeBindings>
                                </ext:NodeBinding>
                              </DataBindings>
                            </ext:TreeStore>
                          </Store>

My razor view code is

Html.X().TreePanel().ID("TreePanel1").Width(350).Height(450).AutoScroll(true)
          .Store(
        
            Html.X().ExtendedTreeStore().ID("TreeStore1").DataSourceID("MnuXmlDataSource")
            .DataBindings(
            
            new Ext.Net.NodeBinding {DataMember="Funzioni",Text="Funzioni",ExpandedField ="Expanded" },
            new Ext.Net.NodeBinding {DataMember="Procedura",TextField="Text" },
              new Ext.Net.NodeBinding {DataMember="Raggruppamento",TextField="Text",NodeIDField="NodeID"}
              .CustomAttributeBindings.Add(
                  new Ext.Net.CustomAttributeBinding { AttributeField="Security" })
                  
                ));

I get two errors

1) on .Databindings :Error 1 The best overloaded method match for 'Ext.Net.TreeStoreBase.Builder<Ext.Net.TreeStore,E xt.Net.TreeStore.Builder>.DataBindings(params Ext.Net.NodeBinding[])' has some invalid arguments

2) on .CustomAttributeBindings.Add : Error 2 Argument 3: cannot convert from 'void' to 'Ext.Net.NodeBinding'

I tried also with this code:

Html.X().TreePanel().ID("TreePanel1").Width(350).Height(450).AutoScroll(true)
          .Store(
        
            Html.X().ExtendedTreeStore().ID("TreeStore1").DataSourceID("MnuXmlDataSource")
            .DataBindings(
            
            new Ext.Net.NodeBinding {DataMember="Funzioni",Text="Funzioni",ExpandedField ="Expanded" },
            new Ext.Net.NodeBinding {DataMember="Procedura",TextField="Text" },
              new Ext.Net.NodeBinding {DataMember="Raggruppamento",TextField="Text",NodeIDField="NodeID"}
              .CustomAttributeBindings.Add(
                  new Ext.Net.CustomAttributeBinding { AttributeField="Security" })
                  
                ));

and i get only one error: Error 1 Non-invocable member 'Ext.Net.NodeBinding.CustomAttributeBindings' cannot be used like a method.

Surely my syntax is wrong.
Can you help me?

Thanks

Hello!

It should look like this:

@(Html.X().TreePanel().ID("TreePanel1").Width(350).Height(450).AutoScroll(true)
    .Store(
         Html.X().TreeStore()
            .ID("TreeStore1")
            .DataSourceID("MnuXmlDataSource")
            .DataBindings(db =>
            {
                db.Add(new Ext.Net.NodeBinding {DataMember = "Funzioni", Text = "Funzioni", ExpandedField = "Expanded"});
            })
    )
)

Also, I don't quite understand what is ExtendedTreeStore?

Hi Baidaly!

Thanks for your answer.
Sorry, "ExtendedTreeStore" is a write error during the transcription of the code.

But my problem about "CustomAttributeBindings" remained.
I am not able to add a "CustomAttributeBindings" to a NodeBinding in razor view.

Any suggestion?

Thanks!

[Daniil]

Regarding @Baidaly's sample:

db.Add(new Ext.Net.NodeBinding
{
    DataMember = "Funzioni",
    Text = "Funzioni",
    ExpandedField = "Expanded",
    CustomAttributeBindings =
    {
        new CustomAttributeBinding() { ... },
        new CustomAttributeBinding() { ... }
    }
});

Hi Daniil,

your sample work fine!

Many thanks, you can close the thread.
