[CLOSED] RemoteValidation ExtraParams are ignored

[daneel]

Looking at the HTTP trace, I see that the extra params aren't included in the request at all:

submitDirectEventConfig={"config":{"serviceParams":"{\"id\":\"Registration\",\"value\":510}"}}
&__EVENTTARGET=ResourceManager1
&__EVENTARGUMENT=Registration|postback|remotevalidation
&Registration_Value=510
&Registration=Euronext
&Registration_SelIndex=9

Here's the form markup:

    <form id="form1" runat="server">
    <ext:ResourceManager ID="ResourceManager1" runat="server">
    </ext:ResourceManager>
<ext:Store runat="server" ID="StoreRegistration">
  <Reader>
    <ext:JsonReader>
      <Fields>
        <ext:RecordField Name="RegistrationId" Type="Int" />
        <ext:RecordField Name="RegistrationName" />
      </Fields>
    </ext:JsonReader>
  </Reader>
</ext:Store>
<ext:FormPanel ID="FormPanel1" 
            runat="server" 
            Title="Remote Validation Form" 
            Padding="5"
            Frame="true"
            LabelWidth="250"
            Width="500"             
            DefaultAnchor="-20">
            <Items>
                            <ext:ComboBox runat="server" ID="Registration" DataIndex="RegistrationId" FieldLabel="Registration name" StoreID="StoreRegistration"
              ValueField="RegistrationId" DisplayField="RegistrationName" Editable="false" AllowBlank="false" IsRemoteValidation="true">
                    <Listeners>
                      <Select Handler="this.remoteValidate();"/>
                      <AfterRender Handler="this.rvConfig.remoteValidated = true;this.rvConfig.remoteValid = true;" />
                    </Listeners>
                      <RemoteValidation OnValidation="CheckDuplicateRegistration">
                          <ExtraParams>
                            <ext:Parameter Name="PersonRegId" Value="400" />
                            <ext:Parameter Name="PersonId" Value="4164" />
                          </ExtraParams>
                      </RemoteValidation>
            </ext:ComboBox>
     </ext:FormPanel>
</form>

And the code for the event handler:

        protected void CheckDuplicateRegistration(object sender, RemoteValidationEventArgs e)
        {
            if (e.Value != null)
            {
                if (e.ExtraParams.Count > 0)
                {
.
.
.
.
                }
            }
       }

I can see from the page source that the extraparams are included in the combo's config:

{
   id:"Registration",
   xtype:"combo",
   fieldLabel:"Registration name",
   dataIndex:"RegistrationId",
   isRemoteValidation:true,
   remoteValidationOptions:{
      extraParams:{
         "PersonRegId":"400",
         "PersonId":"4164"
      }
   },
   allowBlank:false,
   editable:false,
   displayField:"RegistrationName",
   hiddenName:"Registration_Value",
   triggerAction:"all",
   valueField:"RegistrationId",
   store:StoreRegistration,
   submitValue:true,
   listeners:{
      select:{
         fn:function(item,
         record,
         index)         {
            this.remoteValidate();
         }
      }
   }
}

But for some strange reason they don't get included in the request.

Is this a bug or am I missing something?

Hi,

I have tried to reproduce the issue using the code you provided with no success, the extraParams are passed.

I used the following code:

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.ComboBox1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { 1, "item1" },
                new object[] { 2, "item2" },
                new object[] { 3, "item3" }
            };
            store.DataBind();
        }
    }

    protected void CheckDuplicateRegistration(object sender, RemoteValidationEventArgs e)
    {
        e.ErrorMessage = "No ExtraParams";
        if (e.Value != null)
        {
            if (e.ExtraParams.Count > 0)
            {
                X.Msg.Alert("ExtraParams", e.ExtraParams.Count).Show();
                e.Success = true;
            }
        }
    }
</script>

I used your code and modified it to use code-behind and it still doesn't work.
Can you try it with the attached VS2008 project?

Btw, my version of the Ext.Net assembly is 1.0.3960.36328 according to the reference properties

[Daniil]

Yes, it works fine with the latest code, but doesn't work with RC1.

There are two options:

1. Updating from the SVN
2. Waiting RC1. It should come soon.

Okay, not a problem, I've worked around the issue by saving the parameter values (they're only set once) in Viewstate and then reading from that in the remote validation method.

Thanks
