LookUp

appearance, multiple choice, overriding methods, it is possible to use problems and their solutions

LookUp (action) - select a craftsman of the object (putting links to the workman the object).

LookUp (control) - control for selection of artisan object that returns a reference to it.

Return multiple objects

There is a possibility to get all the objects selected on the list for Lookup.

It is used in the constraint editor, where for the limit Среди значений returns all selected on list lucapa objects.

All selected objects can be obtained by contacting DynamicProperties standard of the returned object. Namely:

o.DynamicProperties["retFromObjectListView"] as List<DataObject>

The resulting list will not contain the first selected object o.

Note: for forms with multiple ObjectListView or ObjectHierarchicalView, you need to remove the overload prv_EditData and a subscription to OLV.ReturnData.

Override method Edited

The example shows how you can override the Edited to use the information received from the LookUp data.

public override void Edited(ICSSoft.STORMNET.DataObject dataobject, string contpath, string propertyname)
    {
        base.Edited (dataobject, contpath, propertyname);

        if (propertyname == "Employee")
        {
            Объекты.ДвижениеГруппыОтказнМатер Э = (Объекты.ДвижениеГруппыОтказнМатер)EditManager.DataObject;
            Объекты.Сотрудник р = (Объекты.Сотрудник)Э.Сотрудник;

            Э.ФИОСотрудника = Э.Сотрудник.ОпрПолноеФИО();
            if (р.Должность != null)
            {
                DataServiceProvider.DataService.LoadObject(р.Должность);
                Э.Должность = р.Должность.Наименование;
            }
            else Э.Должность = "";

            EditManager.Change("Posotrudnichat");
            EditManager.Change(Title);
        }

        if (propertyname == "Employee")
        {
            Объекты.ДвижениеГруппыОтказнМатер Э = (Объекты.ДвижениеГруппыОтказнМатер)EditManager.DataObject;
            Объекты.ОтвЗаРешение р = (Объекты.ОтвЗаРешение)Э.УКогоНаходится;

            if (р != null)
            {
                extTextControl1.Text = р.Наименование;
            }
            else extTextControl1.Text = "";
        }
    }

Button display a list of

To add a button to display artisan list to a Lookup, you need to:

To create flat control button
Add icon from ImageList.
At the push of a button to add a call the following functions:

public void ПоказатьСписок()
    {
        SQLWhereLanguageDef langdef = SQLWhereLanguageDef.LanguageDef;
        Function lf = null;

        // generated lf 
        LoadingCustomizationStruct lcs = LoadingCustomizationStruct.GetSimpleStruct(typeof(Лицо), "ЛицоL");
        lcs.LimitFunction = lf;

        ICSSoft.STORMNET.DataObject[] objs = DataServiceProvider.DataService.LoadObjects(lcs);

        if (objs.Length == 0)
        {
            Tools.ShowInformation("Not one person with the specified parameters");
            return;
        }
        else // at least someone found 
        {
            string contpath = "STORMCASE.STORMNET.Generator.SerializeNewEditForm/EditPanel(Panel)/TabControl(Tab" + "Control)/panel(TabPage)/panel(GroupBox)/ctrlЛицо(LookUp)";
            base.OnEdit("Person", EditManager.DataObject, contpath, lf);
        }
    }

The change in appearance

There are two ways to change the images on the buttons LookUp.

1.If you want to change the image within the application, you must initialize staticheskie ImageList_ when the application starts. This list must be present if the image name “LookUp”, “Clear” and “Edit”.

Example:

LookUp.UserImageList.Images.Add("LookUp", Properties.Resources.LookUpImage);
LookUp.UserImageList.Images.Add("Clear", Properties.Resources.ClearImage);
LookUp.UserImageList.Images.Add("Edit", Properties.Resources.EditImage);

2.For a specific instance LookUp using the properties UserImageList you can assign polzovateli ImageList_, which also needs to be images with names “LookUp”, “Clear” and “Edit”.

The size and borders of the buttons

The size of the buttons is set using the properties ButtonSize, changing this property should be complete recalculation of the size of the entire control.

For the display of the buttons property ButtonBorder.

Prohibition of changes in BeforeChangeProperty

Ustanovka trait Cancel in a method BeforeChangeProperty if you change artisan field is not blocking Lookup, and then change the properties.

Change handler look_LookUpEvent

To replace the processor on your look_LookUpEvent, you need to:

create a container-runner
to subscribe to events preserve (to keep),
ask your actions when events occur.

private void look_LookUpEvent1(object sender, System.EventArgs e)
{
    Посетитель oПосетитель = (Посетитель)this.EditManager.DataObject;
    
    Function lf = FunctionBuilder.BuildTrue();

    //create a container-runner 
    ICSSoft.АдресноеБюро.ЛичностьL FormЛичностьL = (ICSSoft.АдресноеБюро.ЛичностьL)      ICSSoft.STORMNET.UI.ContRunner.RunForm(typeof(ICSSoft.АдресноеБюро.ЛичностьL));
    FormЛичностьL.Edit(oПосетитель, "Personality", "Personality",lf);

    //subscribe to events 
    FormЛичностьL.SaveEvent+=new ICSSoft.STORMNET.UI.SaveEventArgsHandler(FormЛичностьL_SaveEvent);FormЛичностьL.CancelEvent+=new ICSSoft.STORMNET.UI.CancelEventArgsHandler(FormЛичностьL_CancelEvent);
}

private void FormЛичностьL_SaveEvent(object sender, ICSSoft.STORMNET.UI.SaveEventArgs e)
{
    //our action 
}

private void FormЛичностьL_CancelEvent(object sender, ICSSoft.STORMNET.UI.CancelEventArgs e)
{
    //our action 
}

Possible problems of using

Standard generated lookup

On the form

If not triggered, the event handler look_LookUpEvent (in the dependent form).

Correctly specify the path on the form before Lookup in the method prv_TuneLookupInformations (in the dependent form).
Specify the form of the call in the method GetEditor independent.
The button LookUp (for example, for Citizenship it will be ctrlГражданство) to hang the handler events LookUp.

this.ctrlГражданство.LookUpEvent += look_LookUpEvent

In GroupEdit

Snap GropEdit to form EditManager
Presence of the handler this.gr_SetupEditorEventHandler type OnSetupEditorEventHandler for the event SetupEditor
Mention GroupEdit in the method prv_TuneLookupInformations (in the dependent form), naprimer:

m_arrGroupEditInformations.Add(
               new ICSSoft.STORMNET.UI.GroupEditInformation(this.ПредметыИзъятия,
               "Imageshare.Predmestie",
               "STORMCASE.STORMNET.Generator.SerializeNewEditForm/EditPanel(Panel)/TabControl(TabControl)/panel(TabPage)/Predmestie(GroupEditBase)"));

Non-standard use cases Lookup

Does not raise a form on Lookup

It is necessary to consider features of the control:

If there is no property whose name is passed as PropertyName, it is best to specify an empty string, otherwise the method Save will not be called.
Nahranie objects that are raised on Lookup scriptizer handled outside the box and the event needs to be written manually.

You should also check:

If the object is stored, from which rises a LookUp.
What forms are raised and with what shape.
Rises with the form on the button LookUp. If Yes, then rises with forms LookUp. If Yes, specify nepravilno parametry. If not raised, neither the button nor from the method, that is, the error most likely is systemic.

Not the message about the preservation of the object when the form is closed

You need to check:

Object has the status Altered
The object has changed its properties from the moment of manual forms for Lookup. When picked up by the Lookup form is the initiator in the method PrepareDataObjectForEdit creates a copy of the data, and at the close compared this copy with the current on the close object. Conservation will only occur if there is a difference between an object and its copy.
Form properly raised in the Lookup:
passes the form object-initiator of the LookUp, not the one that should be edited
indicated the existing property or the empty string

Change the list name to Lookup

Change the name of the list for Lookup at different forms of editing, you can define conditions on the edit form and list form, add a handler for this event. For example, on the edit form when opening a Lookup in a data object add the desired title in the DynamicProperties, and in list form to read.
