[CLOSED] Ext.net Build Scripts with 3rd Party Controls

[pgodwin]

I'm looking at porting the Sencha wrappper for HighCharts (https://github.com/JoeKuan/Highcharts_Sencha) for use as Ext.Net controls.

Before I start writing one by hand, I am curious if the Ext.Net build scripts could be leveraged to do some of this for me? From a quick look it would seem it can parse out the ExtJS code into C# code (among other things), but am curious how flexible that is or if it's been utilised in a such a manner before?

Regards

Hi Peter,

That is an interesting project you are going to deal with!

From a quick look it would seem it can parse out the ExtJS code into C# code

At some point we considered such a possibility, but it has never been implemented. Ext.NET controls are written by hand. Though, there is the Builder, Config and ConfigOptions classes within the Factory folder which are mostly generated automatically parsing Ext.NET controls.

Thanks for the reply Deniil.

I have the following collection:

        
         private HighChartSeriesCollection series;

        [ConfigOption("series", JsonMode.AlwaysArray)]
        [Category("HighChart")]
        [PersistenceMode(PersistenceMode.InnerProperty)]
        [Meta]
        public HighChartSeriesCollection Series
        {
            get
            {
                if (this.series == null)
                {
                    this.series = new HighChartSeriesCollection();
                    this.series.AfterItemAdd += this.AfterItemAdd;
                    this.series.AfterItemRemove += this.AfterItemRemove;
                    
                }
                return this.series;
            }
        }

I configure it as follows:

<a:HighChart runat="server" ID="Test" StoreID="storeTest">
                    <Series>
                        <a:ColumnSerie runat="server" ID="testItem" DataIndex="Value" />
                    </Series>
            </a:HighChart>

However I get the following exception when the page loads:

[Exception: ItemTag validation (_tkn_5): Reference token (testItem_ClientInit) was not found.]
   Transformer.NET.ItemTag.Validate() +215
   Transformer.NET.TextTransformer.Handle() +283

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69

I've gone through the Ext.Net code but can't find a reason for this not to work. Any pointers would be appreciated.

Worked it out. Had to change [ConfigOption("series", JsonMode.AlwaysArray)] to [ConfigOption("series", typeof(ItemCollectionJsonConverter))] and a corresponding change in the ConfigOptions.

Seems obvious in hindsight.
