    [CLOSED] Adding RemoteValidation ExtraParams in server side but when RemoteValidation fired, the ExtraParams are ignored

    Hello:

    I have a user control which has a textField and textField is enable RemoteValidation. I add the ExtraParams to RemoteValidation on the server side, on "OnPreRender" but when the validation fired, I track the HTTP trace and found only "id" and "value" has send to server. The ExtraParams which I added on server side are totally missing.
    here is the example for how I add the ExtraParames in RemoteValidataion in server side.
    textFieldName.RemoteValidation.ExtraParams.Add(new Parameter("planID", "this.PlanId", ParameterMode.Raw));
    Could you tell me what's the problem it is? Thank you

    Tom

    Hi,

    ExtraParams should not be ignored.

    Pleas provide your test case to reproduce the problem.

    Here is my test case which works fine.

    Example

    <%@ Page Language="C#" %>
    
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    
    <script runat="server">
        protected void TextField_Validation(object sender, RemoteValidationEventArgs e)
        {
            X.Msg.Alert("Test", e.ExtraParams["test"]).Show();
            e.Success = true;
        }
    </script>

            <ext:FormPanel runat="server">
                <Items>
                    <ext:TextField runat="server" FieldLabel="TextField" IsRemoteValidation="true">
                        <RemoteValidation OnValidation="TextField_Validation">
                            <ExtraParams>
                                <ext:Parameter Name="test" Value="test" Mode="Value" />
                            </ExtraParams>
                        </RemoteValidation>
                    </ext:TextField>
                </Items>
            </ext:FormPanel>
        </form>
    </body>
    </html>

    Hi Daniil:

    Thank you for the reply. My case is not add the ExtraParams in the page or view.
    Actually I create a user control which is inherit from Ext.Net.Panel. In the user control, I create a TextField which enabled RemoteValidation.
    In the RemoteValidation, I add a Ext.Net.Parametr in ExtraParams. But when the validation fired, the ExtraParams didn't send to server.
    Here is my simplify code.

    UserControlPanel.cs
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using Ext.Net;
    using WBS.Workware.Resources;
    
    namespace WBS.Workware.Web.Controls
    {
        public class PlanDetails : Panel
        {
    
             public string Name
            {
                get
                {
                    return (string)ViewState["Name"];
                }
                set
                {
                    ViewState["Name"] = value;
                }
            }
    
            public int ContainerId
            {
                get
                {
                    return (int) ViewState["ContainerId"];
                }
                set
                {
                    ViewState["ContainerId"] = value;
                }
            }
    
            protected override void OnPreRender(EventArgs e)
            {
                base.OnPreRender(e);
                
                var textFieldName = new TextField()
                                        {
                                            ID = "textName",
                                            Width = 270,
                                            AllowBlank = false,
                                            MaxLength = 50,
                                            MinLength = 4,
                                            FieldLabel = "Name",
                                            ValidateOnBlur = false,
                                            MsgTarget = MessageTarget.Side,
                                            Text = Name,
                                            BlankText = "You must input the name.",
                                            IsRemoteValidation = true,
                                        };
                textFieldName.RemoteValidation.Url = "~/UserControll/CheckName";
                textFieldName.RemoteValidation.Json = true;
                textFieldName.RemoteValidation.Delay = 300;
                textFieldName.RemoteValidation.ExtraParams.Add(new Parameter("containerID", "this.containerId", ParameterMode.Raw));
                textFieldName.Listeners.BeforeRemoteValidation.Handler = "return this.originalIsValid(true);";
                textFieldName.SelectOnFocus = true;
                textFieldName.Focus();
                    this.LayoutConfig.Add(new VBoxLayoutConfig() { Align = VBoxAlign.Stretch, DefaultMargins = "10 25 10 10" });
                    this.Items.Add(textFieldName);
                    this.Items.Add(textAreaDescription);
                    this.Items.Add(textAreaComment);
                base.OnInit(e);
            }
    
            protected override void PreRenderAction()
            {
                this.CustomConfig.Add(new ConfigItem() { Name = "Name", Value = "'" + this.Name + "'", Mode = ParameterMode.Raw });
                this.CustomConfig.Add(new ConfigItem() { Name = "ContainerId", Value = "'" + this.ContainerId + "'", Mode = ParameterMode.Raw });
                base.PreRenderAction();
            }
        }
    }

    Please remove
    textFieldName.RemoteValidation.Json = true;
    Also, I think, this parameter
    new Parameter("containerID", "this.containerId", ParameterMode.Raw)
    will consists "undefined" value, because the TextField ('this' reference) have no "containerId" property.

    I can suggest you to make this parameter within the BeforeRemoteValidation listener:
    textFieldName.Listeners.BeforeRemoteValidation.Handler = @" options.params.containerID = this.ownerCt.containerId;
                                                                return this.originalIsValid(true);";
    A one note more that it looks strange:
    protected override void OnPreRender(EventArgs e)
    {
        base.OnPreRender(e);
    
        ...
    
        base.OnInit(e);
    }
    And, I think, you can use OnInit event instead of OnPreRender.

    HI Daniil:

    I modified the code as you suggested but I got the error message as follow
    This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.

    Use Method parameter oа RemoteValidation
    textFieldName.RemoteValidation.Method = HttpMethod.POST;
    or set attribute [HttpGet] on method CheckName in UserControllController
