Binding

For correct operation of control AjaxGroupEdit, it must implement the interface IAjaxGroupEditCompatible:

namespace ICSSoft.STORMNET.Web.AjaxControls
{
    /// <summary> 
    /// Controls that implement this interface can be embedded in AjaxGroupEdit 
    /// </summary> 
    public interface IAjaxGroupEditCompatible : IGroupEditCompatible
    {
        /// <summary> 
        /// The property to which bendida the value in the column AjaxGroupEdit. 
        /// Put down by AjaxGroupEdit, control only uses the value. 
        /// </summary> 
        string BindingPropertyName { get; set; }

        /// <summary> 
        /// Indicator that is set to true if the control is inside in AjaxGroupEdit. 
        /// Put down by AjaxGroupEdit. 
        /// </summary> 
        bool IsInsideEditor { get; set; }

        /// <summary> 
        /// Generate or not the standard structure for the client binding. 
        /// Simplifies the development of controls with a simple bindinga. 
        /// </summary> 
        bool GenerateDefaultStructForBinding { get; }

        /// <summary> 
        /// The list of external scripts to attach. 
        /// All these scripts in AjaxGroupEdit will connect through the ContextHelper. 
        /// For Example "AjaxDataService.js" 
        /// </summary> 
        List<string> ExternalScriptPaths { get; }

        /// <summary> 
        /// The text of the scripts which will be executed on document ready AjaxGroupEdit 
        /// </summary> 
        List<string> DocumentReadyScripts { get; }
    }
}

An important aspect of working AGE is the client binding that is triggered in javascript.

It works as follows:

  1. Close control should be a json structure containing properties Property - property of the DataObject and ID - ID of the control on the client
  2. By clicking on the button сохранить the value from the control on the client using js will create a new json structure, which will go with the postback to handle server-side WebBinder;

If you enable GenerateDefaultStructForBinding=true, will generate a structure like

{"Property":"Dataromance", "ID" : "ctrl306940bb5b9e4bb98d7c93989c6ae9ed_ctrlдатарождения_ctrl"}

If you create a custom control with a complex client bindinga, to generate this structure will need themselves, checking the value GenerateDefaultStructForBinding == false.

Example:

protected override void Render(HtmlTextWriter writer)
{
    if (IsInsideEditor)
    {
        string valJson = string.Format("`\"Property\":\"{0}\", \"ID\" : \"{1}\"`", BindingPropertyName, ID + "_ctrl");
        writer.AddAttribute("class", "binding");
        writer.AddAttribute("type", "hidden");
        writer.AddAttribute("value", valJson);
        writer.RenderBeginTag(HtmlTextWriterTag.Input);
        writer.RenderEndTag();
    }
}

Important: if you use the standard structure for binding in the value of the ID field of the json structure will be placed ControlToEditClientID.

customize the display of DatePicker in AGE

The easiest way to display a DatePicker for all groupedit application to create the method producing the necessary actions on an instance of the control (which is passed to it as parameters), and assign it a static property InitSettings class DatePicker.

Embedding MasterEditorAjaxLookUp

In AjaxGroupEdit you can use MasterEditorAjaxLookUp. To do this, set WebControlProvider.

An example of a piece of the file WebControlProvider.xml:

  <propertytype name="Tiplady">
    <control typename="" property="" codefile=""/>
    <editcontrol typename="ICSSoft.STORMNET.Web.AjaxControls.MasterEditorAjaxLookUp" property="SelectedMasterPK" codefile=""/>
  </propertytype>

It will look as follows:

Controls for editing

There is a need to define custom controls for viewing and editing properties of objects in AjaxGroupEdit. The controls for viewing are defined in the usual way WebControlProvider. In order to specify the control that will be created to edit the properties, then you need to WebControlProvider add Directive <editcontrol /> with similar properties <control />.

For example, to view the date used ICSSoft.STORMNET.Web.Controls.DateTimeFormattedControl, and to edit ICSSoft.STORMNET.Web.Controls.DatePicker.

It looks as follows:

  <propertytype name="NullableDateTime">
    <control typename="ICSSoft.STORMNET.Web.Controls.DateTimeFormattedControl" property="Text" codefile="DateTimeFormattedControl.ascx"/>
    <editcontrol typename="ICSSoft.STORMNET.Web.Controls.DatePicker" property="Text" codefile="The DatePicker.ascx"/>
  </propertytype>

Read more about WebControlProvider and embedding controls.

Scripts

If the application control interface scripts (on page load), then all the scripts need to connect via ContextHelper and the scripts will automatically be added. If control is necessary connection of external scripts, you need to use a property ExternalScriptPaths interface IAjaxGroupEditCompatible.
