插件中在调用动态表单时，通过DynamicFormShowParameter的CustomParams，增加自定义的参数。

/// 
        /// 库存查询        /// 
        private void ShowMaterialStock()        {            object useOrgId = (this.View.Model.GetValue("FUseOrgId") as DynamicObject)["Id"];            object materialId = this.View.Model.GetPKValue();            List
    
      orgIds = PermissionServiceHelper.GetPermissionOrg(this.Context, new BusinessObject() { Id = K3.Core.SCM.SCMFormIdConst.STK_Inventory }, PermissionConst.View);            DynamicFormShowParameter ShowPara = new DynamicFormShowParameter();            ShowPara.ParentPageId = this.View.PageId;            ShowPara.MultiSelect = false;            ShowPara.FormId = K3.Core.SCM.SCMFormIdConst.STK_InventoryQuery;            ShowPara.Height = 600;            ShowPara.Width = 1000;            string filter = string.Format(" FStockOrgId = {0} And FMaterialId = {1} And FOwnerTypeId='BD_OwnerOrg' And FOwnerId={2} ", useOrgId, materialId, useOrgId);            ShowPara.CustomParams.Add("QueryFilter", filter);            ShowPara.CustomParams.Add("QueryOrgId", (this.View.Model.GetValue("FUseOrgId") as DynamicObject)["Id"].ToString());            this.View.ShowForm(ShowPara);        }
    

目标单据的插件中，通过View.OpenParameter.GetCustomParameter("xxx")获取传递的自定义参数：

/// 
    /// 即时库存查询界面插件    /// 
    public class InventoryQuery : AbstractDynamicFormPlugIn    {        public override void OnInitialize(InitializeEventArgs e)        {            base.OnInitialize(e);            object paraQueryFilter = this.View.OpenParameter.GetCustomParameter("QueryFilter");            object paraOrgId = this.View.OpenParameter.GetCustomParameter("QueryOrgId");                    }    }
