How to use Odata proxy

[PetrSnobelt]

Hello, I found Odata proxy project
http://www.sencha.com/forum/showthre...-for-ExtJS-4.1

But I don't know how to use it.

Should I create my own proxy, or there is simpler way?

Thank you

You have to implement it as server side class and use in the store
You can investigate Ext.Net Proxy classes to understand how to implement own Proxy

Thank you, I solve it using following code. It works fantastic with webapi :-)

public class OdataProxy : Ext.Net.AjaxProxy
{
        [Ext.Net.ConfigOption]
        [System.ComponentModel.DefaultValue("odata")]
        protected override string Type { get {return "odata"; } }        
}

I add suport for GridFilters, if anyone is interested.

Markup

                     <ext:GridFilters runat="server" ParamPrefix="$filter">
                        <Filters>
                            <ext:NumericFilter DataIndex="Id" />
                            <ext:StringFilter DataIndex="Name"  />
                            <ext:StringFilter DataIndex="Category"  />
                            <ext:NumericFilter DataIndex="Price" />                            
                        </Filters>
                        <CustomConfig>
                            <ext:ConfigItem Name="buildQuery" Mode="Raw" Value="buildQueryOdata" />
                        </CustomConfig>
                    </ext:GridFilters>

And Javascript function:

 //http://docs.sencha.com/ext-js/4-1/source/FiltersFeature.html#Ext-ux-grid-FiltersFeature-method-buildQuery
//http://www.odata.org/documentation/uri-conventions
        function buildQueryOdata(filters) {
            var p = {}, i, f, dataPrefix,
                len = filters.length,
                odata = "",
                value;

            for (i = 0; i < len; i++) {
                f = filters[i];

                if (odata != "") odata += " and ";
                value = f.data.type == "string" ? "'" + f.data.value + "'" : f.data.value;

                if (f.data.comparison != null) {
                    odata += f.field + " " + f.data.comparison + " " + value;
                } else {
                    //substringof('Alfreds', CompanyName) eq true
                    odata += "substringof(" + value + "," + f.field + ") eq true";
                }                
            }

            var p = {};
            if (odata != "") p[this.paramPrefix] = odata;
            return p;            
        }

Good news...

We're going to add full OData Proxy support to Ext.NET 2.2. With some luck this functionality should be committed to SVN this week.
